1、49沥青砼路面机械摊铺编制日期:2004年5月10日编制单位:目录第一卷 沥青砼路面机械摊铺2第一卷 沥青砼路面机械摊铺 1特点 l1施工速度快、社会效益好 机械化摊铺沥青类道面施工速度、效益较人工摊铺大为提高,在一般施工条件下,每台班单机摊铺量可达近千吨混合料,尤其在工期短、社会影响大的工程施工中更能体现优点。 12材料施工中各种温度得以保证 由于在摊铺中混合料的施工温度得到了保证,对保证质量所必须控制的摊铺温度,初、复、终压温度都能实行有效控制。 13施工质量高 使用摊铺机施工,利用摊铺机的振捣机构及自动找平系统,道面的整体质量得以保证,尤其在道面的压实度、平整度和厚度这三个主要质量指标上
2、更比人工摊铺易于控制。 14保证了混合料的均匀 沥青混合料在拌和厂内拌和后,经过卸料、运输、卸料,造成材料离析,这种不均匀的材料经摊铺机螺旋式分布器在分配材料时的搅拌可得到第二次拌和,以弥补材料本身的缺陷。 2适用范围 21运用于各种宽度大于3.0m的沥青类道路、广场、机场跑道。 22尤其适用于工期紧、质量要求高的大面积沥青混合料摊铺。 3施工工艺(见下页) 4施工要求 41施工前准备 411根据设计横断面,合理布置摊铺机排列宽度。 412根据质量要求验收基层标高、平整度,避免因底、基层的标高、平整度不良影响面层。413根据对底、基层的验收情况和沥青面层的设计要求计算各控制点的放样数据,选定合
3、适的抛高系数(抛高系数的确定必须综合考虑摊铺厚度、材料级配、摊铺机振捣行程、摊铺速度)。道路基层测量清扫放基准线摊铺机定位预热及安装自动找平仪检查料温度启动送料装置均匀分布材料料车至摊铺机卸料摊铺机起步及检查各仪表情况人工修整缺陷及边接缝测量温度压路机进行初压、复压、终压清理工地及机械内余料复验各项质量指标 414根据测量数据及现场施工条件,决定放样工具和放样基准线,注意城市道路的锯齿型街沟。 415 根据材料级配和施工厚度确定摊铺机和压路机的振捣(动)频率和振幅。 42摊铺机准备及摊铺 421摊铺机定位后要预热熨平装置,避免拉毛施工面。 422安装自动找平装置后要检查其完好性能及操作灵活性,
4、避免因仪器的失灵造成动作失误。 423在冷横缝处起步时,根据不同松方系数,熨平装置底部垫好所需厚度木板。 4,24混合料温度符合摊铺温度时,倒料至摊铺机料斗,摊铺机起步摊铺阶段速度不宜过快,一般控制在23mmin为佳。 425检查摊铺机各部分协调情况,摊出混合料的情况是否正常,并及时给予调整。一般调整工作在摊铺机起步后10m内完成。 426转入正常摊铺,按需要调整摊铺速度,经常检查传感器与基准线的情况,以保证摊铺厚度。 43压路机碾压 431压路机使用前先检查所有喷水装置是否完好,机械是否有漏油现象。432压路机碾压顺序先轻后重,先边后中。碾压温度及速度见表。433压路机碾压轮宽为1/3,初压
5、用轻型压路机,复、终压用重型压路机,碾压次数见表。 434压路机碾压遇纵缝为热拼时,压路机碾压要离边缘20cm,避免压塌边缘影响整体平整度。 44其他注意事项及操作方法441纵横接缝的处理轮子半轮相叠向外移动2米碾压成型沿横缝方向振动一遍指挥压路机碾压专人测温控制纵横缝碾压温度碾压阶段摊铺阶段人工找平筛细骨料 填补空隙专人检查纵缝、轮子30cm在新摊铺面层上振动碾压一遍横缝、沿摊铺方向前进510cm人工找平纵缝注意抛高系数及搭接宽度摊 铺横缝掌握摊铺机起步段控制方法喷粘层油清扫深度56cm铣刨边口成直角横缝用1米直尺寻找切点定位划直线纵缝去处松散部分准备阶段 442摊铺时若发现有明显高低影响平
6、整时需耙松缺陷处的混合料,经人工修补,检测后再压实。 443城市道路施工遇窨井时需采取以下措施,底层沥青混合料施工前要移去井座采取保护措施后摊铺,摊铺后立刻人工挖出原井基,恢复井座;摊铺面层混合料后及时用人工修正井座边后碾压,碾压时遇井座要避免振动。 444机械摊铺沥青混合料应尽量避免过多的停顿,要求送料均匀到达施工现场,当发生意外情况,材料到现场间隔较长时,在温度许可的前提下,适当压车是必要的。 445已铺筑的沥青料未碾压时,操作人员不得踏立上去。 5质量标准 采用本工法后施工质量应达到中华人民共和国建设部标准CJJI90市政道路工程质量检验评定标准。 6机具设备7施工安全71操作人员应穿工
7、作皮鞋及工作服。72施工区域要有明显标志和封闭护栏。73机械起步时要有专人注意周围环境。74材料车进场要有专人指挥。75交通繁忙地段要设专职纠察。8劳动组织9经济效益沥青混合料路面采用机械化施工后,班摊铺量为手工摊铺的45倍,缩短了施工周期,提高了劳 动生产率,并且由于路面平整好,碾压密实,延长了道路的实际使用寿命。(英文版 ) Two regulations promulgated for implementation is in the party in power for a long time and the rule of law conditions, the implementa
