四川省南部至成都高速公路项目LM4标段施工组织设计c、配合比检验。按以上生产配合比,用室内小型拌和机拌制沥青混合料,做浸水48小时马歇尔试验,检验残留稳定度,必须满足设计规定。沥青混合料的动稳定度和冻融劈裂强度也必须满足设计要求。②生产配合比设计:a、确定各热料仓矿料和矿粉的用量。必须从二次筛分后进入各热料仓的矿料取样进行筛分,根据筛分结果,通过计算,使矿质混合料的级配接近目标配合比并符合设计规定,以确定各热料仓矿料和矿粉的用料比例,供拌和机控制室使用。同时反复调整冷料仓进料比例,以达到供料均衡。b、确定最佳油石比。取目标配合比设计的最佳油石比OAC和OAC±0.3%、OAC±0.6%五个油石比,取以上计算的矿质混合料,用试验室的小型拌和机拌制沥青混合料进行马歇尔试验,按目标配合比设计方法绘图分析,得出OAC1和OAC2后综合确定生产配合比的最佳油石比OAC。按以上方法确定的OAC可能与目标配合比的OAC不一致,如相差不超过0.2个百分点,应按生产配合比确定的OAC进行试件拌和试铺,或分析确定试拌试铺用油石比;如相差超过0.2个百分点,应找出原因,进一步试验分析后确定试拌试铺用油石比。c、配合比检验。按以上生产配合比,用室内小型拌和机拌制沥青混合料,做浸水48小时马歇尔试验,检验残留稳定度,必须满足设计规定。沥青混合料的动稳定度和冻融劈裂强度也必须设计要求。③生产配合比验证:用生产配合比进行试拌,沥青混合料的技术指标合格后铺筑试铺段。取试铺用的沥青混合料进行马歇尔试验检验和沥青含量、筛分试验,检验标准配合比矿料合成级配中,至少应包括0.075mm、2.36mm、4.75mm及公称最大粒径筛孔的通过率接近生产配合比级配值,并避免在0.3mm~0.6mm处出现驼峰。由此确定正常生产用的标准配合比。关于沥青混合料马歇尔室内试验中几点注意事项:a.进行目标配合比设计和生产配合比设计时,制备试件的混合料,需采用小型沥青混合料拌和机拌和,以模拟生产实际情况。b.每组试件个数一律用6个。c.试件成型温度:对于普通道路石油沥青,应根据粘温曲线确定。在缺乏沥青粘度条件时,参照以下温度成型:开始击实温度不低于140~145℃(改性沥青不低于160~165℃),试模应按规定预热。d.沥青混合料试件密度试验方法:面层沥青混合料统一用表干法的毛体积相对密度。nthemainterminal,andthetelephoneOfficeisresponsibleforprovidingtheappropriatesizeadapterpatchpanelsandelectricalprotectionunit.(Shuttlebus)wiring(IDF)setupintheworkshoponthesecondfloorofthebuilding,locatedintheDistrictofweakelectricalcabinets(well).EngineroomplacedinsidetheCabinet,IDFplacedastandard40Ucabinetsforinstallationofnetworkandwiringdevices,managementcomputerandtelephoneinformation.CabinetdistributionframearemadeofSuperfiveRJ45patchpanelhorizontaltwistedpairconnections.Computerinformationmanagement,adminareausingthejumpers,whichusesprivateRJ45-RJ45softjumpersfornetworkdeviceswithjumpershoppingbetweenallswitches,changes,expansionandmaintenanceweredonequicklyinthewiringcloset.TwistedlengthCentreroomislocatedonthesecondfloor,outwardradiationofeachline(exceptsomepointsmayexceed)doesnotexceed100metresinlength,allinformationforthevariousfloorsallrooms(distributionCabinet)unifiedmanagement.Districtworkshopbuildingdistributionlines(IDF)viafiberopticcablesconnectedtothetotalroomcabinets.Fiberlengthwere:workshopstwoIDF:totalmorethan1200squaremeters,doublethenumberofstrandscanbecalculatedbymultiplyingtheaveragelengthofthenumberofinformationpointsare.Averagelevelofeachlengthofcable:L=[(S1+S2)/2]+L1+L2l:averagelengthofcable;L1:MDFcableallowance;L2:otherallowancesS1:minimumhorizontalcablelength;S2:maximumhorizontallengthofcable;Officebuildingofinformation:aminimumof26meters,thelongestwas92meters,L=[(28+92)/2]+2.5+1=62.5m;Totallengthof62.5mx792=49500-meterineachbox(KFT)by300meterspercarton;Thetwisted-paircableboxyouwant=49500÷300=165(KFT);lossesnotincluded,eachabout15meters.Metallineslot,andmetallinetubeof-95-

四川省南部至成都高速公路项目LM4标段施工组织设计F40-2004《公路沥青路面施工技术规范》规定操作。在试铺路面的铺筑过程中,监理工程师应一起参加,检查施工工艺、技术措施是否符合要求,测温、观色、取样,并记录试验与检测结果,检查各种技术指标情况,对出现的问题提出改进意见。各层试铺,必须力争一次铺筑成功,使试铺面层成为正式路面的组成部分。否则应予铲除。试铺路面的质量检查频率应根据需要比正常施工时适当增加(一般增加一倍)。试铺结束后,试铺路面应基本上无离析和石料压碎现象,经检测各项技术指标均符合规定,施工单位应立即提出试铺总结报告,由监理工程师审查确认后,即可作为申报正式开工的依据。(6)沥青路面施工工艺厂拌沥青路面其施工过程可分为沥青混合料的拌制与运输、现场铺筑碾压两个阶段,下面将分别对各工艺叙述如下:①沥青混合料的拌和与运输我部投入该项工程一座DG-4000型大型沥青砼拌和楼,产量320吨/小时,为间歇式,而其特有的计量方式不仅能保证较准确的配合比,而且其环保功能也比较先进,它的计量精度:骨料为±0.5%,矿粉±0.3%,沥青:±0.3%,烟尘浓度≤15mg/Nm3。为了保证拌制的沥青混合料能满足施工规范的要求,在开机前必须对拌和设备进行一次全面细致的检查,注意联接的紧固情况,检查搅拌器内有无积存余料,冷料运输器是否运转正常和有无跑偏现象,仔细检查沥青管道各个接头,尤其是沥青计量设备计量是否准确,严禁吸沥青管有漏气现象,检查电气系统,对于机械运转部分,还要检查传动链的张紧度等情况。以确保设备运转正常,拌制的沥青混合料符合规范要求。在拌制沥青混合料和摊铺沥青混合料之前,根据确定的配合比进行试拌。试拌时对所有的各种矿料和沥青应严格计量,通过试拌和抽样检验确定每盘热料的配合比及其重量,适宜的沥青用量,拌和时间,矿料和沥青加热温度,以及沥青混合料出厂的温度。对试拌的沥青混合料进行试验之后,即可选定最佳的施工的配合比。为使沥青混合料拌和均匀,在拌制时我部将严格按照各类沥青混合料的拌制温度控制沥青和所用石料的加热温度与拌和温度。保证经过拌和后的混合料均匀一致,无花白、结块现象。石油沥青材料的拌制温度:种类沥青材料加热温度矿料加热温度混合料出场温度石油沥青材料150~160℃165~185℃150~165℃SBS改性沥青165~175℃180~200℃175~185℃nthemainterminal,andthetelephoneOfficeisresponsibleforprovidingtheappropriatesizeadapterpatchpanelsandelectricalprotectionunit.(Shuttlebus)wiring(IDF)setupintheworkshoponthesecondfloorofthebuilding,locatedintheDistrictofweakelectricalcabinets(well).EngineroomplacedinsidetheCabinet,IDFplacedastandard40Ucabinetsforinstallationofnetworkandwiringdevices,managementcomputerandtelephoneinformation.CabinetdistributionframearemadeofSuperfiveRJ45patchpanelhorizontaltwistedpairconnections.Computerinformationmanagement,adminareausingthejumpers,whichusesprivateRJ45-RJ45softjumpersfornetworkdeviceswithjumpershoppingbetweenallswitches,changes,expansionandmaintenanceweredonequicklyinthewiringcloset.TwistedlengthCentreroomislocatedonthesecondfloor,outwardradiationofeachline(exceptsomepointsmayexceed)doesnotexceed100metresinlength,allinformationforthevariousfloorsallrooms(distributionCabinet)unifiedmanagement.Districtworkshopbuildingdistributionlines(IDF)viafiberopticcablesconnectedtothetotalroomcabinets.Fiberlengthwere:workshopstwoIDF:totalmorethan1200squaremeters,doublethenumberofstrandscanbecalculatedbymultiplyingtheaveragelengthofthenumberofinformationpointsare.Averagelevelofeachlengthofcable:L=[(S1+S2)/2]+L1+L2l:averagelengthofcable;L1:MDFcableallowance;L2:otherallowancesS1:minimumhorizontalcablelength;S2:maximumhorizontallengthofcable;Officebuildingofinformation:aminimumof26meters,thelongestwas92meters,L=[(28+92)/2]+2.5+1=62.5m;Totallengthof62.5mx792=49500-meterineachbox(KFT)by300meterspercarton;Thetwisted-paircableboxyouwant=49500÷300=165(KFT);lossesnotincluded,eachabout15meters.Metallineslot,andmetallinetubeof-95- 四川省南部至成都高速公路项目LM4标段施工组织设计生产的沥青混合料成品应及时运往施工现场。根据施工的具体位置和现场的实际情况,以及我部的拌合能力、摊铺能力、混合料运距,所需混合料的种类和数量等,我部以30T以上的自倾卸汽车运送沥青混合料。对沥青混合料检测其出厂温度和运到现场温度。运料车在运料前底板上均匀地涂上一层1:3的油水隔离剂,防止混合料粘到运输车辆底板上,拌合机向运料车放料时,运料车应前后移动,分几堆装料,以减少粗集料的离析现象,同时运料车的运输能力比拌和能力和摊铺能力略有富余。运输车都必须用篷布覆盖,气温较低时采用双层篷布夹棉被的方式进行覆盖,用以对混合料进行保温、防雨和避免混合料受污染,对运到施工现场的混合料若已发生冷却离析、结块或被雨淋湿以及在运料车辆卸料时滞留在车上的混合料都应废弃。连续摊铺过程中,运料车应在摊铺机前10~30cm处停住,不得撞击摊铺机,卸料过程中运料车应挂空档,由摊铺机推动前进。对运至铺筑现场的沥青混合料的每车均要进行温度检测,并满足温度控制要求。①沥青混凝土路面摊铺1、施工准备:沥青层铺筑前,应对基层或下封层的厚度,密实度,平整度,路拱等进行检查。若有松散、坑槽、软弹或表面浮尘等,必须在面层铺筑之前整修完毕,并应清扫干净。特别对桥头及隧道两端基层发现的沉陷,则应在两端全宽范围内进行挖填处理,将两端缺陷处理干净,并经监理工程师检验合格,分项工程开工报告批准后,方可进行施工。2、施工放样:施工放样应在下承层准备好后进行,包括标高测定与平面控制两项内容。标高测定的目的是确定下承层表面高程与原设计高程相差的误差值,针对ABG型沥青摊铺机具有自动找平装置的特点,在高程控制上采用基准线钢丝法。在边侧专门设置符合设计纵坡的参考弦线钢丝,让传感器的触件沿着弦线移动。如下图所示:细钢丝→立杆→标桩→张拉器两立杆间距一般为5~10m,在弯道处的间距要短些。标桩是用来测定拉线的标高,敷设基准线时将基一端固定,另一端接于张拉器上。除按规定的纵坡保证各支点都有正确的标高位置外,还要注意其纵向走向的正确性,最好使每根立杆与路中线的距离相等,这样就兼作导向线。对敷设好的基准线必须复核其标高的正确性。nthemainterminal,andthetelephoneOfficeisresponsibleforprovidingtheappropriatesizeadapterpatchpanelsandelectricalprotectionunit.(Shuttlebus)wiring(IDF)setupintheworkshoponthesecondfloorofthebuilding,locatedintheDistrictofweakelectricalcabinets(well).EngineroomplacedinsidetheCabinet,IDFplacedastandard40Ucabinetsforinstallationofnetworkandwiringdevices,managementcomputerandtelephoneinformation.CabinetdistributionframearemadeofSuperfiveRJ45patchpanelhorizontaltwistedpairconnections.Computerinformationmanagement,adminareausingthejumpers,whichusesprivateRJ45-RJ45softjumpersfornetworkdeviceswithjumpershoppingbetweenallswitches,changes,expansionandmaintenanceweredonequicklyinthewiringcloset.TwistedlengthCentreroomislocatedonthesecondfloor,outwardradiationofeachline(exceptsomepointsmayexceed)doesnotexceed100metresinlength,allinformationforthevariousfloorsallrooms(distributionCabinet)unifiedmanagement.Districtworkshopbuildingdistributionlines(IDF)viafiberopticcablesconnectedtothetotalroomcabinets.Fiberlengthwere:workshopstwoIDF:totalmorethan1200squaremeters,doublethenumberofstrandscanbecalculatedbymultiplyingtheaveragelengthofthenumberofinformationpointsare.Averagelevelofeachlengthofcable:L=[(S1+S2)/2]+L1+L2l:averagelengthofcable;L1:MDFcableallowance;L2:otherallowancesS1:minimumhorizontalcablelength;S2:maximumhorizontallengthofcable;Officebuildingofinformation:aminimumof26meters,thelongestwas92meters,L=[(28+92)/2]+2.5+1=62.5m;Totallengthof62.5mx792=49500-meterineachbox(KFT)by300meterspercarton;Thetwisted-paircableboxyouwant=49500÷300=165(KFT);lossesnotincluded,eachabout15meters.Metallineslot,andmetallinetubeof-95- 四川省南部至成都高速公路项目LM4标段施工组织设计3、气候条件:沥青混合料的摊铺应避免在雨天进行。当路面滞水或潮湿时,应暂停施工。施工气温低于10℃或大风时,应停止摊铺,对于未经压实即遭受雨淋的沥青混合料全部清除。4、机械摊铺沥青混合科:采用两台210kw以上沥青摊铺机梯队摊铺,纵横向距离、重叠按规范要求。沥青中面层施工时应采用配备浮动基准梁或非接触式平衡装置的摊铺设备。首次摊铺时,先准备一块标准木板,宽为20cm,长为摊铺机熨平板的长度,厚度为混合料的松铺厚度。将摊铺机熨平板坐在标准木板上,并调整料位器,使厚薄指示灯熄灭,然后上料摊铺。每次摊铺结束时,应先关闭仰角。下次摊铺前应将前次摊铺的端部切掉,并在接缝处刷涂一层粘层沥青,然后将熨平板坐在清理好的端部,垫上松铺厚度的木块,然后调整料位器进行摊铺。沥青混合料应缓慢均匀连续地摊铺。在摊铺过程中不得随意变换速度或中途停顿,摊铺机螺旋送料器要不停地转动,两侧应保持不少于送料器高度2/3的混合料,并保证在摊铺机全宽断面上不发生离析。沥青混合料的摊铺温度应控制在145~165℃的范围内,不超过165℃,摊铺避免在雨天进行,路面有积水时应暂停施工。沥青混合料的摊铺速度一般控制在2~3m/min为宜,以使其摊铺用料量和拌和机的产量相适应,同时为保证连续摊铺,摊铺机前至少保证有足够的料车在等候卸料。其它构造物的接触面上,应均匀地刷上粘层沥青,然后才能紧靠这些接触摊铺沥青混合料。人工找补或更换混合料应在主管人员指导下进行。缺陷较严重时,应予以铲除,并调整摊铺机或改进摊铺工艺。当属机械原因引起严重缺陷时,应立即停止摊铺。人工修补时,工人不宜站在热混合料层面上操作。③沥青凝土路面碾压沥青混合料摊铺整平之后,由专人负责测量混合料温度以决定是否压实。开始碾压的温度,沥青混合料正常温度宜控制在145~160℃;碾压终了温度,改性沥青混合料不低于120℃。碾压分初压、复压和终压三个阶段进行。初压时压路机的驱动轮朝向摊铺方向进行碾压,最好使每次往返的轮迹完全重叠,待压路机退到已压实的路段后,再转向侧移,与相邻轮迹重叠1/3轮宽。复压作业应本着“先边后中,先慢后快”的原则进行,碾压到无轮迹为止。终压应nthemainterminal,andthetelephoneOfficeisresponsibleforprovidingtheappropriatesizeadapterpatchpanelsandelectricalprotectionunit.(Shuttlebus)wiring(IDF)setupintheworkshoponthesecondfloorofthebuilding,locatedintheDistrictofweakelectricalcabinets(well).EngineroomplacedinsidetheCabinet,IDFplacedastandard40Ucabinetsforinstallationofnetworkandwiringdevices,managementcomputerandtelephoneinformation.CabinetdistributionframearemadeofSuperfiveRJ45patchpanelhorizontaltwistedpairconnections.Computerinformationmanagement,adminareausingthejumpers,whichusesprivateRJ45-RJ45softjumpersfornetworkdeviceswithjumpershoppingbetweenallswitches,changes,expansionandmaintenanceweredonequicklyinthewiringcloset.TwistedlengthCentreroomislocatedonthesecondfloor,outwardradiationofeachline(exceptsomepointsmayexceed)doesnotexceed100metresinlength,allinformationforthevariousfloorsallrooms(distributionCabinet)unifiedmanagement.Districtworkshopbuildingdistributionlines(IDF)viafiberopticcablesconnectedtothetotalroomcabinets.Fiberlengthwere:workshopstwoIDF:totalmorethan1200squaremeters,doublethenumberofstrandscanbecalculatedbymultiplyingtheaveragelengthofthenumberofinformationpointsare.Averagelevelofeachlengthofcable:L=[(S1+S2)/2]+L1+L2l:averagelengthofcable;L1:MDFcableallowance;L2:otherallowancesS1:minimumhorizontalcablelength;S2:maximumhorizontallengthofcable;Officebuildingofinformation:aminimumof26meters,thelongestwas92meters,L=[(28+92)/2]+2.5+1=62.5m;Totallengthof62.5mx792=49500-meterineachbox(KFT)by300meterspercarton;Thetwisted-paircableboxyouwant=49500÷300=165(KFT);lossesnotincluded,eachabout15meters.Metallineslot,andmetallinetubeof-95- 四川省南部至成都高速公路项目LM4标段施工组织设计消除路面表面的碾压轮迹和提高表层的密实度和平整度。碾压时压路机开进的方向应平行于路中心线,并由一侧路缘压向路中心。双轮压路机每次重叠30cm,轮胎式压路机亦应重叠碾压。碾压中保持均匀速度行驶,不得在新铺混合料上停留,转弯。④特殊路段的碾压1、弯道或交叉口碾压:先从弯道内侧或弯道较低一边开始碾压。对急弯应尽可能采取直线碾压,并逐一转换车道,对缺角处用小型压路机压实,压实中转向与速度相吻合,尽可能用振动碾压,以减少剪切力。2、路边碾压:压路机在没有支承边的面层上碾压时,可在离边缘30~10cm处开始碾压,使之形成一条支承侧面,以减少沥青混合料碾压时铺层塌边。碾压未压部分时,压路机每次只能向边缘推进10cm。3、陡坡碾压:在陡坡上碾压时,压路机的很大部分作用力将向下坡方向,因而增加了混合料顺坡下移的趋势。在压实时先用轻型压路机预压。无论上坡,下坡,从动轮始终朝着摊铺方向,即从动轮在前,驱动轮在后。这样从动轮起到了预压作用,从而使沥青混合料能够承受驱动轮所产生的剪切力。陡坡碾压中,压路机的起动、停止、变速要平稳,避免速度过高或过低,混合料温度不宜过高。特别要注意的是在当天碾压的尚未冷却的沥青混合料面层上,不得停放任何机械设备或车辆,不得散落矿料、油料等杂物。(6)沥青混凝土路面接缝施工①横接缝施工横缝应与路中线垂直。从接缝处起继续摊铺混合料前应用3m直尺检查端部平整度,当不符合要求时应予清除。摊铺时应调好预留高度,接缝处摊铺层施工结束后再用三米直尺检查平整度,当符合要求时,应趁混合料尚未冷却时立即处理。接缝时应先用切缝机切齐,铺筑前必须将切缝边缘清扫干净,沿已切齐的缝边用热沥青混合料覆盖预热,覆盖层厚15cm,待接缝处变软之后,将所覆盖的沥青混合料清除,并涂洒少量粘层沥青,使压路机轮宽的10~20cm置于新铺的沥青混合料上碾压,然后逐渐横移直到整个滚轮进入新铺层碾压,相邻两幅及上下层的接缝应错开1m以上,中下层的接缝可采用斜接缝,在铺筑面层时应采用垂直的平接缝。为保证压实质量应先静压,后振动碾压,充分将接缝压实紧密。②纵缝施工nthemainterminal,andthetelephoneOfficeisresponsibleforprovidingtheappropriatesizeadapterpatchpanelsandelectricalprotectionunit.(Shuttlebus)wiring(IDF)setupintheworkshoponthesecondfloorofthebuilding,locatedintheDistrictofweakelectricalcabinets(well).EngineroomplacedinsidetheCabinet,IDFplacedastandard40Ucabinetsforinstallationofnetworkandwiringdevices,managementcomputerandtelephoneinformation.CabinetdistributionframearemadeofSuperfiveRJ45patchpanelhorizontaltwistedpairconnections.Computerinformationmanagement,adminareausingthejumpers,whichusesprivateRJ45-RJ45softjumpersfornetworkdeviceswithjumpershoppingbetweenallswitches,changes,expansionandmaintenanceweredonequicklyinthewiringcloset.TwistedlengthCentreroomislocatedonthesecondfloor,outwardradiationofeachline(exceptsomepointsmayexceed)doesnotexceed100metresinlength,allinformationforthevariousfloorsallrooms(distributionCabinet)unifiedmanagement.Districtworkshopbuildingdistributionlines(IDF)viafiberopticcablesconnectedtothetotalroomcabinets.Fiberlengthwere:workshopstwoIDF:totalmorethan1200squaremeters,doublethenumberofstrandscanbecalculatedbymultiplyingtheaveragelengthofthenumberofinformationpointsare.Averagelevelofeachlengthofcable:L=[(S1+S2)/2]+L1+L2l:averagelengthofcable;L1:MDFcableallowance;L2:otherallowancesS1:minimumhorizontalcablelength;S2:maximumhorizontallengthofcable;Officebuildingofinformation:aminimumof26meters,thelongestwas92meters,L=[(28+92)/2]+2.5+1=62.5m;Totallengthof62.5mx792=49500-meterineachbox(KFT)by300meterspercarton;Thetwisted-paircableboxyouwant=49500÷300=165(KFT);lossesnotincluded,eachabout15meters.Metallineslot,andmetallinetubeof-95- 四川省南部至成都高速公路项目LM4标段施工组织设计表层的纵缝应顺直,且宜留在车道区划线的位置上,如当日摊铺时采用梯队作业的纵缝应采用热接缝,施工应将已铺的混合料留下10~20cm宽暂不碾压,作为后摊铺部分的高程基准面,再后作跨缝碾压以消除缝迹,当日先后修筑的两个车道,摊铺宽度应与已铺车道重叠3~5cm。不在同一天铺筑的相邻车道,在摊铺新料之前,就对原路面边缘加以修理,要求边缘切齐,缝边保持垂直,并涂刷一层粘层沥青后方可摊铺新料。纵缝在摊铺之后立即碾压,让压路机大部分压在已铺好的路面上,仅让10~15cm的宽度压在新铺的车道上,然后,逐渐移动跨过纵缝,从层式沥青路面上下层的接缝相互错开20~30cm,做成台阶式衔接。(7)沥青砼路面检查质量管理与检查验收:①质量检查与控制措施:沥青混合料的生产,每日应作抽提试验(包括马歇尔稳定试试验);严格控制各种矿料的拌和质量,拌和后的沥青混合料应均匀一致,无花白,无粗细料分离和结团成块现象;摊铺时应严格掌握摊铺厚度和平整度,避免矿料离析,要注意摊铺和碾压温度。沥青混合料生产过程中,应满足规范和设计的检查项目与频度,对各种原材料进行抽样试验,其质量应符合规范规定的技术要求。每个检查项目的平行试验次数或一次试验的试样数必须按相关试验规程的规定执行,并按规范要求进行综合评定,其评定结果应符合规范要求,否则必须返工。②质量目标:要求合格率达到100%。外观要求沥青砼表面平整密实,不应有泛油、松散、裂缝、粗细料明显分离现象,搭接处紧密、平顺、烫缝不应枯焦。保证所施工的沥青砼路面压实度、平整度、纵断高程、宽度、厚度、横坡、等各项指标全部符合规范要求。(9)开放交通待摊铺层完全自然冷却,混合料表面温度低于50度后,方可开放交通。(10)沥青路面面层施工工艺框图nthemainterminal,andthetelephoneOfficeisresponsibleforprovidingtheappropriatesizeadapterpatchpanelsandelectricalprotectionunit.(Shuttlebus)wiring(IDF)setupintheworkshoponthesecondfloorofthebuilding,locatedintheDistrictofweakelectricalcabinets(well).EngineroomplacedinsidetheCabinet,IDFplacedastandard40Ucabinetsforinstallationofnetworkandwiringdevices,managementcomputerandtelephoneinformation.CabinetdistributionframearemadeofSuperfiveRJ45patchpanelhorizontaltwistedpairconnections.Computerinformationmanagement,adminareausingthejumpers,whichusesprivateRJ45-RJ45softjumpersfornetworkdeviceswithjumpershoppingbetweenallswitches,changes,expansionandmaintenanceweredonequicklyinthewiringcloset.TwistedlengthCentreroomislocatedonthesecondfloor,outwardradiationofeachline(exceptsomepointsmayexceed)doesnotexceed100metresinlength,allinformationforthevariousfloorsallrooms(distributionCabinet)unifiedmanagement.Districtworkshopbuildingdistributionlines(IDF)viafiberopticcablesconnectedtothetotalroomcabinets.Fiberlengthwere:workshopstwoIDF:totalmorethan1200squaremeters,doublethenumberofstrandscanbecalculatedbymultiplyingtheaveragelengthofthenumberofinformationpointsare.Averagelevelofeachlengthofcable:L=[(S1+S2)/2]+L1+L2l:averagelengthofcable;L1:MDFcableallowance;L2:otherallowancesS1:minimumhorizontalcablelength;S2:maximumhorizontallengthofcable;Officebuildingofinformation:aminimumof26meters,thelongestwas92meters,L=[(28+92)/2]+2.5+1=62.5m;Totallengthof62.5mx792=49500-meterineachbox(KFT)by300meterspercarton;Thetwisted-paircableboxyouwant=49500÷300=165(KFT);lossesnotincluded,eachabout15meters.Metallineslot,andmetallinetubeof-95-

四川省南部至成都高速公路项目LM4标段施工组织设计第1章重点(关键)和难点工程的施工方案、方法及措施一、改性沥青砼施工1、改性沥青砼面层施工工艺改性沥青面层的施工与普通沥青面层的施工基本相同。改性沥青的施工其控制的技术关键是沥青及沥青混合料温度的控制。改性沥青路面施工主要分为三大部分,即室内原材料的检测、改性沥青混凝土的拌和、改性沥青混凝土的铺筑及碾压成型。(1)沥青沥青采用优质SBS改性石油沥青,在使用前严格按下表所列技术要求进行检验。确认无明显分离、凝聚现象,且各项性能指标符合要求,报监理工程师批准方可使用。(2)粗集料混合料类型石料压碎值(%)洛杉矶磨耗损失表面相对密实吸水率(%)坚固性(%)针片状颗粒含量水洗法<0.075mm软石含量磨光值(PSV)与沥青粘附性上面层≤26≤28≥2.6≤2.0≤12≤10%≤1%≤3%≥425级(3)细集料表现相对密度坚固性(>0.3mm)部分砂当量亚甲蓝值棱角性≥2.6≥12%≥60%≤25g/kg≥30S(4)矿粉质量符合设计要求,(具体要求见矿粉技术质量要求)(5)沥青抗剥落剂改性沥青面层应根据使用集料的实际情况,掺入适当比例的沥青抗剥落剂,掺加量一般为沥青含量的3-4‰,用于改善上面层集料玄武岩粘附性差的缺点。使其粘附性达5级。2、沥青混合料的日常检验沥青混合料的日常检验主要做马歇尔试验和抽提筛分试验,用于检验混合料的油石比、矿料级配和沥青砼的物理力学性质。油石比设计值的允许误差为±0.2%。对沥青用量的检验采用两种方法:nthemainterminal,andthetelephoneOfficeisresponsibleforprovidingtheappropriatesizeadapterpatchpanelsandelectricalprotectionunit.(Shuttlebus)wiring(IDF)setupintheworkshoponthesecondfloorofthebuilding,locatedintheDistrictofweakelectricalcabinets(well).EngineroomplacedinsidetheCabinet,IDFplacedastandard40Ucabinetsforinstallationofnetworkandwiringdevices,managementcomputerandtelephoneinformation.CabinetdistributionframearemadeofSuperfiveRJ45patchpanelhorizontaltwistedpairconnections.Computerinformationmanagement,adminareausingthejumpers,whichusesprivateRJ45-RJ45softjumpersfornetworkdeviceswithjumpershoppingbetweenallswitches,changes,expansionandmaintenanceweredonequicklyinthewiringcloset.TwistedlengthCentreroomislocatedonthesecondfloor,outwardradiationofeachline(exceptsomepointsmayexceed)doesnotexceed100metresinlength,allinformationforthevariousfloorsallrooms(distributionCabinet)unifiedmanagement.Districtworkshopbuildingdistributionlines(IDF)viafiberopticcablesconnectedtothetotalroomcabinets.Fiberlengthwere:workshopstwoIDF:totalmorethan1200squaremeters,doublethenumberofstrandscanbecalculatedbymultiplyingtheaveragelengthofthenumberofinformationpointsare.Averagelevelofeachlengthofcable:L=[(S1+S2)/2]+L1+L2l:averagelengthofcable;L1:MDFcableallowance;L2:otherallowancesS1:minimumhorizontalcablelength;S2:maximumhorizontallengthofcable;Officebuildingofinformation:aminimumof26meters,thelongestwas92meters,L=[(28+92)/2]+2.5+1=62.5m;Totallengthof62.5mx792=49500-meterineachbox(KFT)by300meterspercarton;Thetwisted-paircableboxyouwant=49500÷300=165(KFT);lossesnotincluded,eachabout15meters.Metallineslot,andmetallinetubeof-95- 四川省南部至成都高速公路项目LM4标段施工组织设计(1)、检查每天的沥青用量及生产的混合料总量进行校核。(2)、测定实验室拌制沥青混合料中实用油石比与抽提法得出的油石比的差值,建立试验室抽提法测得的油石比修正系数。3、沥青砼配合比设计配合比设计采用马歇尔配合比设计方法,其试验技术标准同下面层。在配合比的基础上,在规定的试验条件下进行车辙试验、浸水马歇尔试验和冻融劈裂试验,并符合规范和设计要求。改性沥青混合料矿料级配中0.075mm、2.36mm、4.75mm三挡筛的通过率应尽量接近规定的级配范围中值。4、施工现场的有关检验施工现场的检验为厚度、压实度、平整度(采用钻孔取芯和连续式平整度仪)、摩擦系数、构造深度和弯沉。高程、横坡、宽度(采用水准仪检测和皮尺量测)。5、沥青混合料的拌和在拌制混合料的过程中必须严格掌握沥青的集料的加热温度,改性沥青混合料的拌和温度应通过直接测定改性沥青粘度—温度曲线中的沥青粘度值为0.17±0.02Pa.s时所对应的温度作为拌和温度,或通过试验路段的实验结果调整,同时考虑运输距离、摊铺与压实能力的因素。改性沥青混合料面层的压实温度应通过改性沥青粘度—温度曲线中的沥青粘度值为0.28±0.03Pa.s时所对应的温度作为压实温度,或通过试验路段的试验结果调整。根据我们以往成功经验,沥青的加热温度控制在165℃-175℃,矿料的加热温度控制在180℃-200℃,混合料出厂温度175℃-185℃。在拌制混合料的过程中,拌和楼逐盘打印沥青及各种矿料的用量以便及时发现混合料的级配是否发生变化,并定期对拌和楼的计量和测温进行校核。在上面层混合料的过程中拌和时间为干拌5S湿拌35S(此时整盘混合料的拌合时间为55-60秒)便能使所有集料颗料全部裹复沥青结合料,保证经过拌和混合料均匀,无花白结块现象。混合料的贮存时间不宜超过24h。在拌制过程中注意检查混合料的均匀性,及时分析异常情况,如混合料有无花白料(原因:料温偏低、拌和时间偏短、粉尘含量偏大)、枯料(原因:细集料含量水量大、拌和温度高)和没有色泽(原因:沥青加热温度过高)等,如确任是质量问题,作废料处理并急时纠正。每天上、下午各取组样式做马歇尔试验。检验油石比、矿料级配和沥青混凝土的物理力学性。nthemainterminal,andthetelephoneOfficeisresponsibleforprovidingtheappropriatesizeadapterpatchpanelsandelectricalprotectionunit.(Shuttlebus)wiring(IDF)setupintheworkshoponthesecondfloorofthebuilding,locatedintheDistrictofweakelectricalcabinets(well).EngineroomplacedinsidetheCabinet,IDFplacedastandard40Ucabinetsforinstallationofnetworkandwiringdevices,managementcomputerandtelephoneinformation.CabinetdistributionframearemadeofSuperfiveRJ45patchpanelhorizontaltwistedpairconnections.Computerinformationmanagement,adminareausingthejumpers,whichusesprivateRJ45-RJ45softjumpersfornetworkdeviceswithjumpershoppingbetweenallswitches,changes,expansionandmaintenanceweredonequicklyinthewiringcloset.TwistedlengthCentreroomislocatedonthesecondfloor,outwardradiationofeachline(exceptsomepointsmayexceed)doesnotexceed100metresinlength,allinformationforthevariousfloorsallrooms(distributionCabinet)unifiedmanagement.Districtworkshopbuildingdistributionlines(IDF)viafiberopticcablesconnectedtothetotalroomcabinets.Fiberlengthwere:workshopstwoIDF:totalmorethan1200squaremeters,doublethenumberofstrandscanbecalculatedbymultiplyingtheaveragelengthofthenumberofinformationpointsare.Averagelevelofeachlengthofcable:L=[(S1+S2)/2]+L1+L2l:averagelengthofcable;L1:MDFcableallowance;L2:otherallowancesS1:minimumhorizontalcablelength;S2:maximumhorizontallengthofcable;Officebuildingofinformation:aminimumof26meters,thelongestwas92meters,L=[(28+92)/2]+2.5+1=62.5m;Totallengthof62.5mx792=49500-meterineachbox(KFT)by300meterspercarton;Thetwisted-paircableboxyouwant=49500÷300=165(KFT);lossesnotincluded,eachabout15meters.Metallineslot,andmetallinetubeof-95- 四川省南部至成都高速公路项目LM4标段施工组织设计6、沥青混合料的运输沥青混合料的运输与普通沥青砼的运输要求相类似,但改性由于温度要求较高,故可视摊铺现场拌和楼之间的实际距离确定运料车车辆数量,一般较普通沥青多2-5辆。混合料加盖双层苫布夹绵被保温。7、改性沥青表面层的摊铺SBS改性沥青混合料的摊铺温度控制在160-170℃的范围内,开机前应提前0.5~1h预热熨平板至不低于100℃,铺筑过程中选择熨平板的振捣或夯锤压实装置,提高初始压实度,沥青混合料的摊铺速度控制在2~4m/min,以使其摊铺用料量和拌合机的产量相适应,同时为保证连续摊铺,摊铺机前至少应保证有3辆以上料车在等候卸料。8、改性沥青面层碾压改性沥青的压实必须在摊铺后紧接着进行,碾压长度控制在20-30m。采用高温碾压,不得等混合料稍冷以后碾压。在初压和复压的过程中,宜采用同类压路机并列成梯对压实。压实的目的是提高沥青混合料的强度和稳定行。沥青混合料摊铺整平之后,由专人负责测量混合料温度以决定是否开始碾压。碾压分初压,复压和终压三个阶段进行。压路机在碾压过程中每次停机位置不能在同一断面上,而应该成45度角停放。每次碾压转向时应在已压实的路面上进行。二、SMA-13沥青砼上面层施工(控制要点)1、施工准备(1)、检查调试各种施工设备,使其处于性能良好状态。(2)、对下承层进行清扫,污染严重的地方要根据规范要求进行特殊处理。下承层表面清扫干净处理后喷洒粘层油,根据摊铺能力确定喷洒段落,若喷洒面积太大、摊铺跟不上时间长了容易造成粘层油污染,层间结合不好,影响油层质量。2、混合料的拌和(1)、拌和前将各种集料包括矿粉充分的烘干,沥青加热到180℃,集料加热温度控制在180℃以上,拌和时间一般控制在50~60秒之间,根据出料情况拌和时间可适当延长,混合料的出厂温度不低于180℃。混合料只限当天使用。nthemainterminal,andthetelephoneOfficeisresponsibleforprovidingtheappropriatesizeadapterpatchpanelsandelectricalprotectionunit.(Shuttlebus)wiring(IDF)setupintheworkshoponthesecondfloorofthebuilding,locatedintheDistrictofweakelectricalcabinets(well).EngineroomplacedinsidetheCabinet,IDFplacedastandard40Ucabinetsforinstallationofnetworkandwiringdevices,managementcomputerandtelephoneinformation.CabinetdistributionframearemadeofSuperfiveRJ45patchpanelhorizontaltwistedpairconnections.Computerinformationmanagement,adminareausingthejumpers,whichusesprivateRJ45-RJ45softjumpersfornetworkdeviceswithjumpershoppingbetweenallswitches,changes,expansionandmaintenanceweredonequicklyinthewiringcloset.TwistedlengthCentreroomislocatedonthesecondfloor,outwardradiationofeachline(exceptsomepointsmayexceed)doesnotexceed100metresinlength,allinformationforthevariousfloorsallrooms(distributionCabinet)unifiedmanagement.Districtworkshopbuildingdistributionlines(IDF)viafiberopticcablesconnectedtothetotalroomcabinets.Fiberlengthwere:workshopstwoIDF:totalmorethan1200squaremeters,doublethenumberofstrandscanbecalculatedbymultiplyingtheaveragelengthofthenumberofinformationpointsare.Averagelevelofeachlengthofcable:L=[(S1+S2)/2]+L1+L2l:averagelengthofcable;L1:MDFcableallowance;L2:otherallowancesS1:minimumhorizontalcablelength;S2:maximumhorizontallengthofcable;Officebuildingofinformation:aminimumof26meters,thelongestwas92meters,L=[(28+92)/2]+2.5+1=62.5m;Totallengthof62.5mx792=49500-meterineachbox(KFT)by300meterspercarton;Thetwisted-paircableboxyouwant=49500÷300=165(KFT);lossesnotincluded,eachabout15meters.Metallineslot,andmetallinetubeof-95-

四川省南部至成都高速公路项目LM4标段施工组织设计(1)、压实分为初压、复压和终压三个环节,SMA混合料的初压温度不低于170℃,复压温度不低于160℃,终压温度不低于125℃,须采用钢轮压路机,不能用胶轮压路机,因为SMA混合料的粘性大,易粘轮,轮胎揉搓碾压会使马蹄脂上浮,造成构造深度降低,甚至泛油。(2)、混合料摊铺后,应紧跟着在尽可能高的温度下碾压,不得在低温状态下反复碾压SMA,以防止磨掉石料棱角或压碎石料、破坏石料嵌挤。(3)、初压采用刚性碾静压,长度一段不大于20m,采用两台压路机同时进行。初压遍数为一遍,复压紧跟在初压后进行,采用重型振动压路机,碾压应遵循“高温压实、紧跟慢压、高频低幅”的原则,碾压遍数不少于3~4遍,终压采用刚性静压,紧接在复压后进行以消除轮迹。防止过度碾压,过度碾压会出现弹簧现象,混合料无法稳定,当发现构造深度小,马蹄脂有上浮现象时,应立即停止。在不产生严重摊移和裂缝前提下,初压、复压、终压都尽可能在高温前提下进行,(4)、为防止混合料粘附在轮子上,应适当洒水使轮子保持湿润,严格控制水量,以不粘轮为度。碾压应纵向进行,并由摊铺路幅的低边向高边进行,相邻碾压段重叠至少50cm,初压时始终让从动轮在后,避免由于温度高轮前易留下波浪影响平整度。碾压应均衡地进行,碾压速度不得超过3.5km/h,倒退时要关闭振动,端部方向要渐渐地改变,严禁急转弯。严禁在新铺的混合料上转向、调头、突然刹车或停机休息,不得在当天铺筑的路面上长时间停留或过夜;防止矿料、油料和杂物散落在面层上,造成对面层污染。6、接缝(1)、SMA抗滑表层严禁纵向接缝,横向施工采用平接缝,平接缝切缝在混合料尚未在空气中冷却结硬之前进行,切缝后用水冲洗干净,待干燥后,途刷粘层油,方可铺筑新混合料。(2)、为保证横向接缝处的平整度,应用钢轮压路机进行横向碾压,从先铺路面上跨缝逐渐移向新铺面层,初压后用人工找平,用3m直尺检测控制。直到平整度满足要求为止,并注意上、下层横向接缝要错开1m以上。nthemainterminal,andthetelephoneOfficeisresponsibleforprovidingtheappropriatesizeadapterpatchpanelsandelectricalprotectionunit.(Shuttlebus)wiring(IDF)setupintheworkshoponthesecondfloorofthebuilding,locatedintheDistrictofweakelectricalcabinets(well).EngineroomplacedinsidetheCabinet,IDFplacedastandard40Ucabinetsforinstallationofnetworkandwiringdevices,managementcomputerandtelephoneinformation.CabinetdistributionframearemadeofSuperfiveRJ45patchpanelhorizontaltwistedpairconnections.Computerinformationmanagement,adminareausingthejumpers,whichusesprivateRJ45-RJ45softjumpersfornetworkdeviceswithjumpershoppingbetweenallswitches,changes,expansionandmaintenanceweredonequicklyinthewiringcloset.TwistedlengthCentreroomislocatedonthesecondfloor,outwardradiationofeachline(exceptsomepointsmayexceed)doesnotexceed100metresinlength,allinformationforthevariousfloorsallrooms(distributionCabinet)unifiedmanagement.Districtworkshopbuildingdistributionlines(IDF)viafiberopticcablesconnectedtothetotalroomcabinets.Fiberlengthwere:workshopstwoIDF:totalmorethan1200squaremeters,doublethenumberofstrandscanbecalculatedbymultiplyingtheaveragelengthofthenumberofinformationpointsare.Averagelevelofeachlengthofcable:L=[(S1+S2)/2]+L1+L2l:averagelengthofcable;L1:MDFcableallowance;L2:otherallowancesS1:minimumhorizontalcablelength;S2:maximumhorizontallengthofcable;Officebuildingofinformation:aminimumof26meters,thelongestwas92meters,L=[(28+92)/2]+2.5+1=62.5m;Totallengthof62.5mx792=49500-meterineachbox(KFT)by300meterspercarton;Thetwisted-paircableboxyouwant=49500÷300=165(KFT);lossesnotincluded,eachabout15meters.Metallineslot,andmetallinetubeof-95- 四川省南部至成都高速公路项目LM4标段施工组织设计三、长大纵坡路段沥青混合料施工(控制要点)1、长大纵坡沥青路面的破坏形式沥青路面的破坏形式主要有:车辙、裂缝以及由水损坏引起的松散剥落、翻浆、唧浆等。在长大纵坡路段,沥青路面出现的最主要的破坏形式为车辙破坏,且陡坡的上坡一侧的车辙比下坡要严重,超、重载车多的方向车辙严重。在长大纵坡路段,由于纵坡大、重载车多、荷载作用时间长,路面结构受到水平剪应力会较水平路段增大3—5倍,这将造成沥青层出现剪切破坏,易出现结构性车辙。而在高温时,长大纵坡路段由于车辆的频繁变重,使得沥青层产生永久变形和塑性流动,从而形成沥青混凝土的侧向流动变形,出现失稳性车辙。同时,汽车在雨雪天行驶于长大纵坡路段时,由于防滑链、防滑钉的使用,使得轮迹处出现磨损性车辙。再者,长大纵坡路段在混合料施工时,不易压实,路面残留空隙率过大,而在气候的行车作用下,混合料进一步地压密,面层会出现压密性车辙。2、混合料施工前准备长大纵坡路段施工前与其他路段基本相同,应加强材料控制并保持下承层的清洁、干燥、坚实,无松散石料、尘土与杂质,不容许有油污,表面平整。3、施工过程中混合料离析的防治(1)纵向离析的防治实际摊铺过程中主要通过摊铺机的机械控制来防止沥青混合料产生离析。主要通过选用高性能的摊铺机,调整超声波料位器及随机适度调整螺旋前导料板并在螺旋分料器两端改装反向叶片等途径来防治。(2)横向离析的控制解决横向离析的采取以下几种措施:①混合料应采用大吨位卡车运输;②自卸卡车在装料时移动装料,并按车厢前后中的装料顺序;③从储料仓卸料时,不要每次都将卸料舱里的料卸光,应留适量的余料,以防止形成同心圆形的离析。在施工中运料车的数量根据运距的远近适当增减。到达指定位置或运输车辆缓慢接近摊铺机,并在距离摊铺机l0~20cm的范围内停下,摊铺机接触上车辆后轮时,方可起升料斗,使混合料缓慢地喂入摊铺机。(3)温度离析的控制目前主要采取以下两种方式来控制温度离析:①nthemainterminal,andthetelephoneOfficeisresponsibleforprovidingtheappropriatesizeadapterpatchpanelsandelectricalprotectionunit.(Shuttlebus)wiring(IDF)setupintheworkshoponthesecondfloorofthebuilding,locatedintheDistrictofweakelectricalcabinets(well).EngineroomplacedinsidetheCabinet,IDFplacedastandard40Ucabinetsforinstallationofnetworkandwiringdevices,managementcomputerandtelephoneinformation.CabinetdistributionframearemadeofSuperfiveRJ45patchpanelhorizontaltwistedpairconnections.Computerinformationmanagement,adminareausingthejumpers,whichusesprivateRJ45-RJ45softjumpersfornetworkdeviceswithjumpershoppingbetweenallswitches,changes,expansionandmaintenanceweredonequicklyinthewiringcloset.TwistedlengthCentreroomislocatedonthesecondfloor,outwardradiationofeachline(exceptsomepointsmayexceed)doesnotexceed100metresinlength,allinformationforthevariousfloorsallrooms(distributionCabinet)unifiedmanagement.Districtworkshopbuildingdistributionlines(IDF)viafiberopticcablesconnectedtothetotalroomcabinets.Fiberlengthwere:workshopstwoIDF:totalmorethan1200squaremeters,doublethenumberofstrandscanbecalculatedbymultiplyingtheaveragelengthofthenumberofinformationpointsare.Averagelevelofeachlengthofcable:L=[(S1+S2)/2]+L1+L2l:averagelengthofcable;L1:MDFcableallowance;L2:otherallowancesS1:minimumhorizontalcablelength;S2:maximumhorizontallengthofcable;Officebuildingofinformation:aminimumof26meters,thelongestwas92meters,L=[(28+92)/2]+2.5+1=62.5m;Totallengthof62.5mx792=49500-meterineachbox(KFT)by300meterspercarton;Thetwisted-paircableboxyouwant=49500÷300=165(KFT);lossesnotincluded,eachabout15meters.Metallineslot,andmetallinetubeof-95- 四川省南部至成都高速公路项目LM4标段施工组织设计使用重搅拌螺旋机构来减轻或消除温度离析,使用变径变螺旋输送器,仅当宽螺距时混合料才能进入摊铺;窄螺距时混合料重新搅拌,该过程将冷粗料和热料彻底重新拌合,消除了运输过程中产生的温度离析和级配离析.(4)纵坡路段混合料施工离析的控制施工中控制混合料的摊铺宽度和速度。摊铺速度的变化会导致摊铺厚度的变化,从而产生粗细集料出现离析。在施工中把摊铺机的摊铺速度控制在2.5~3m/min.采用两台摊铺机并机梯形作业的方式;分路幅多次摊铺时,注意纵向接缝处两侧粗料较多,难以压实,平整度不好控制。4、沥青混合料施工质量控制为了保证修筑出高质量的沥青路面,施工过程中应从以下方面对混合料生产、摊铺、碾压进行控制:(1)经过目标配合比设计、生产配合比设计、生产配合比验证阶段,确定的标准配合比在施工过程中不得随意变更。稳定合理的配合比是长大纵坡路段沥青混凝土质量保证的重要前提。为保证混合料配合比不出现较大的偏差,严格控制冷料仓的进料比例与速度。通过雨季对细集料的遮盖,以及根据材料的变化和热料仓中不同规格热料的充盈量,及时合理调整冷料仓的进出料比例,尽量稳定混合料的产量。(2)加强对成品料的检测和控制。在生产加工过程中,应随机进行抽提试验,检查沥青混合料的级配,取料位置为料车。检测成品料时,应严格执行成品料秤质量的例行监控测试要求。改善成品料组成分析实验的技术,定期检查沥青抽提仪的误差是否走出允许范围,仔细、正确地进行混合料采样并分析料样的代表性,纠正可能出现的偏差细节,以精确的试验数据为依据来指导日常生产。(3)碾压过程中合理提高沥青混凝土的压实度,适当减少空隙率。沥青混凝土的压实度控制标准上面层按98%,中、下面层按97%,同时为降低实测空隙率,马歇尔设计目标空隙率的范围控制在3.0%~5.0%,路面的实测空隙率不超过7%,一般在6%左右。沥青混凝土路面施工过程中实际空隙率测定时,采用实测密度与相对理论密度双控的方法,保证沥青上面层相对理论密度不低于最大理论相对密度的94%,中、下面层相对理论密度不低于最大理论相对密度的93%.(4)碾压过程中加强沥青混凝土施工温度及碾压方式的控制,严格按照“紧跟、慢压、高频、低幅”的压实方针,即压路机必须紧跟在摊铺机后面将压路机驱动轮从低处向高处,高振、低静的原则进行nthemainterminal,andthetelephoneOfficeisresponsibleforprovidingtheappropriatesizeadapterpatchpanelsandelectricalprotectionunit.(Shuttlebus)wiring(IDF)setupintheworkshoponthesecondfloorofthebuilding,locatedintheDistrictofweakelectricalcabinets(well).EngineroomplacedinsidetheCabinet,IDFplacedastandard40Ucabinetsforinstallationofnetworkandwiringdevices,managementcomputerandtelephoneinformation.CabinetdistributionframearemadeofSuperfiveRJ45patchpanelhorizontaltwistedpairconnections.Computerinformationmanagement,adminareausingthejumpers,whichusesprivateRJ45-RJ45softjumpersfornetworkdeviceswithjumpershoppingbetweenallswitches,changes,expansionandmaintenanceweredonequicklyinthewiringcloset.TwistedlengthCentreroomislocatedonthesecondfloor,outwardradiationofeachline(exceptsomepointsmayexceed)doesnotexceed100metresinlength,allinformationforthevariousfloorsallrooms(distributionCabinet)unifiedmanagement.Districtworkshopbuildingdistributionlines(IDF)viafiberopticcablesconnectedtothetotalroomcabinets.Fiberlengthwere:workshopstwoIDF:totalmorethan1200squaremeters,doublethenumberofstrandscanbecalculatedbymultiplyingtheaveragelengthofthenumberofinformationpointsare.Averagelevelofeachlengthofcable:L=[(S1+S2)/2]+L1+L2l:averagelengthofcable;L1:MDFcableallowance;L2:otherallowancesS1:minimumhorizontalcablelength;S2:maximumhorizontallengthofcable;Officebuildingofinformation:aminimumof26meters,thelongestwas92meters,L=[(28+92)/2]+2.5+1=62.5m;Totallengthof62.5mx792=49500-meterineachbox(KFT)by300meterspercarton;Thetwisted-paircableboxyouwant=49500÷300=165(KFT);lossesnotincluded,eachabout15meters.Metallineslot,andmetallinetubeof-95- 四川省南部至成都高速公路项目LM4标段施工组织设计碾压,确保在高温条件下碾压,以求取得良好效果。同时高频和低幅的碾压对提高沥青混凝土的压实度,防止石料损伤,保持石料良好的棱角性和嵌挤作用很重要。另摊铺混合料尽量采取从低处往高处进行。四、路面工程质量通病防治。(一)如何预防水泥混凝土路面与沥青混凝土路面结合部位的病害1、在水泥混凝土路面与沥青混凝土路面相接施工时,严格控制两种路面的施工质量。首先在路基挖填时保证按设计要求施工,选用水稳性较好的土,严格控制这一“特殊”段的压实质量。由于这一段是采用压路机压,对于不容易压实到位的端部,可以采用气夯夯实。夯时应严格分层,每10cm左右加达夯实。水泥混凝土路面施工和沥青混凝土路面施工时,施工操作人员要把好铺筑材料质量关。2、应充分认识到水泥混凝土路面与沥青混凝土路面相接处虽然工程量小,但其技术要求和难度比一般路段路面的要求要高。因为它是整个路面质量较薄弱的部分,受汽车荷载冲击最大,容易出现质量问题,而且修复起来也较困难,所以在思想上要高度重视这段的路面质量。施工时,要加大现场的管理力度,现场严格监控质量,做好原始记录。必要时可拍照(隐蔽部位),为日后出现质量问题时的修复工作提供准确的依据,以便于查找病害原因,采取补救措施。(二)碎石轧制中采用的机械设备(颚式机、锤式机)的组合及料场筛孔级对碎石成品质量有所影响,如何从源头抓起,保证材料的生产质量1、选择碎石供料场时,应尽量选择生产稳定的大型碎石场。2、最好的办法是施工单位自采或联营生产碎石。3、用于生产沥青混凝土路面表面层的抗滑规格料和粒径偏小的规格料宜用颚、锤式机组合的联合碎石机生产,一破用颚式机,二破用锤式机,这样生产的石料,针片状较少。4、震动筛要采用多级筛分、分级越多,生产的石料级配越好。5、集料的常规性试验应在碎石场进行,一旦发现偏差,可随时调整碎石机口或更换筛网。6、在第一级碎石机的进料口处,设人剔除风化石及泥块,(三)反射裂缝的防治严格控制基层材料中粉料的含量及塑性指数,小于0.075MM的颗粒含量不应超过规范要求。nthemainterminal,andthetelephoneOfficeisresponsibleforprovidingtheappropriatesizeadapterpatchpanelsandelectricalprotectionunit.(Shuttlebus)wiring(IDF)setupintheworkshoponthesecondfloorofthebuilding,locatedintheDistrictofweakelectricalcabinets(well).EngineroomplacedinsidetheCabinet,IDFplacedastandard40Ucabinetsforinstallationofnetworkandwiringdevices,managementcomputerandtelephoneinformation.CabinetdistributionframearemadeofSuperfiveRJ45patchpanelhorizontaltwistedpairconnections.Computerinformationmanagement,adminareausingthejumpers,whichusesprivateRJ45-RJ45softjumpersfornetworkdeviceswithjumpershoppingbetweenallswitches,changes,expansionandmaintenanceweredonequicklyinthewiringcloset.TwistedlengthCentreroomislocatedonthesecondfloor,outwardradiationofeachline(exceptsomepointsmayexceed)doesnotexceed100metresinlength,allinformationforthevariousfloorsallrooms(distributionCabinet)unifiedmanagement.Districtworkshopbuildingdistributionlines(IDF)viafiberopticcablesconnectedtothetotalroomcabinets.Fiberlengthwere:workshopstwoIDF:totalmorethan1200squaremeters,doublethenumberofstrandscanbecalculatedbymultiplyingtheaveragelengthofthenumberofinformationpointsare.Averagelevelofeachlengthofcable:L=[(S1+S2)/2]+L1+L2l:averagelengthofcable;L1:MDFcableallowance;L2:otherallowancesS1:minimumhorizontalcablelength;S2:maximumhorizontallengthofcable;Officebuildingofinformation:aminimumof26meters,thelongestwas92meters,L=[(28+92)/2]+2.5+1=62.5m;Totallengthof62.5mx792=49500-meterineachbox(KFT)by300meterspercarton;Thetwisted-paircableboxyouwant=49500÷300=165(KFT);lossesnotincluded,eachabout15meters.Metallineslot,andmetallinetubeof-95-
