11、线改建工程第十一合同段。东起义居村东口，西至离石南关口，起讫桩号为K725+200K738+071.321主线全长12.6公里。采用二级公路标准：设计年限15年，设计时速40公里/小时，路面设计荷载BZZ-100。下面层设计为4.0cm厚沥青碎石。二、施工组织机构1、组织机构：施工负责人：杜建亮技术负责人：刘金旺 现场负责人：岳明亮试验负责人：刘新平质检负责人：张亚军料场负责人：高林顺机械负责人：冯文斌专职安全员：雷双马2、机械组合2000型沥青拌和设备套、洒水车2台、20T自卸汽车8辆、50装载机3台、WPD750型摊铺机、26T胶轮压路机12T双光轮压路机各1台三、施工工艺1、施工准备（1
12、）在试验段开工前，由监理工程师认可的试验室根据规范和设计要求，对拟采用的各种集料、填料和沥青进行原材料试验并进行混合料组成设计，根据试验室配合比在拌合站试拌，以确保混合料级配组成、结合料含量、拌合温度、马歇尔稳定度、流值、密实度、空隙率等技术指标符合规范要求。同时对用于本工程的全部的试验仪器进行调试，配备足够的熟练的试验人员后，以上试验数据及集料类型、集料来源、沥青来源、种类等一并呈报监理工程师审批。根据试验段总结的数据确定混合料的稳定性及拌和、运输、摊铺、碾压和各机械设备的配合和组合，并选定各层的摊铺速度、松铺厚度、摊铺机与压路机组合及碾压方式和遍数等。（2）据计划安排，准备足够数量施工用的
13、粗集料、细集料、填料、沥青，各种材料进场前对其质量进行严格检查，质量不合格不得使用。面层施工前对下承层按质量标准进行验收，质量合格后方可进行该层施工。（3）对工程用的各种施工机具进行检查维修，确保路面工程施工连续均衡顺利进行。（4）沥青混合料配比试验原材料准备：准备好符合要求的道路石油沥青、碎石料、砂及矿粉，计算出各种材料的用量比例，使混合料级配组成符合要求，初步选定各种材料的用量比例。马歇尔试验：以推荐的沥青含量的中值为中值，按0.5%的沥青含量间隔，用已初步选定的各种矿料比例作马歇尔试件，测定试件的密度，计算空隙率、沥青饱和度、矿料间隙率等物理指标；进行马歇尔试验，测定稳定度、流值等物理力
14、学指标。绘制密度、稳定度、流值、空隙率、饱和度同沥青含量的关系图，综合选定满足各项指标要求的最佳沥青含量。 水稳定性检验：按选定的最佳沥青含量制作马歇尔试件，进行浸水马歇尔试验，检验是否符合规范要求，如水稳定性检验不合格，则需重新调整沥青含量及配比，必要时增加抗剥离剂措施等重新进行试验，直到符合要求为止。最后确定各种矿料(及抗剥离剂)的比例及沥青含量。2、沥青碎石下面层施工程序：测量放样挂线沥青混合料拌和运输摊铺碾压养生3、施工方案：沥青混合料采用2000型拌和站拌制。4.5m沥青混凝土摊铺机摊铺。4、施工工艺：(1)透层沥青施工材料要求： 沥青透油层：透层沥青采用慢裂洒布型乳化沥青PC-2。
15、石屑：石屑采用石灰岩石屑，粒径在23mm之间，石屑干净无泥土等杂物。施工：施工前对基层进行全面检查，先施工放样，放出洒布边线，用鼓风机认真清扫，使基层表面无浮土，干燥、洁净。洒布沥青时，对结构物予以覆盖保护，以免造成污染。按试验段确定用量定好车速，一次喷洒成功。对未洒布到的地方用人工补洒，对局部未渗入基层的多余沥青及时清除。沥青洒布24小时后，撒布一层石屑，用量约23m31000m2，匀铺一层，然后用6-8t钢筒式压路机稳压两遍。在基层未验收合格或气温低于10或降雨时，不进行施工，施工后，及时封闭交通。透层沥青在沥青碎石下面层施工前至3天洒布，让透层沥青充分渗入基层。(2)热拌沥青混合料面层施
16、工材料准备：各种材料的料场及沥青生产厂经监理工程师认可后，开始进料。拌和站严格控制各种用料的质量并备足够数量的材料，以满足施工进度要求。 沥青混合料的拌和： 根据试验选定并经监理工程师批准的原材料沥青配合比，进行沥青混合料拌和施工，并严格地按照操作工艺操作，以满足本合同段的沥青混合料质量要求。在拌和过程中，按要求进行各种检测工作，实验室至少每天上、下午各做一次沥青砼的马歇尔试验，以监测稳定度、流值、空隙率、密度、级配及油石比的指标波动是否满足规范要求，以便及时予以调整，同时检测每批进场沥青针入度、稳定度、软化点及抽验进场骨料的规格和材质等。沥青混合料的拌合设备拟采用60连续型和500间歇式拌制
17、设备，该设备生产过程全部自动控制，其步骤如下：向总控制室电脑输入沥青混合料的级配资料，然后由输送带将各集料装进相应的冷料仓，经初步计量后进入加热滚筒加热，自动控制加热温度，再筛分各热料仓，由控制室发出指令自动计量后进入拌合缸，同时自动加入经计量的沥青，充分拌合后进入储料仓，等待汽车装运。对于沥青采用导热油加热，加热油温度控制在150170范围内，矿料加热温度比沥青加热温度高1020，混合料出厂温度控制在140165，当沥青混合料出厂温度过高(超出高限30时)，已影响沥青与集料的粘结力，混合料不再使用。沥青混合料的运输： 沥青混合料运输用8T以上自卸汽车，运输车的数量根据拌和站生产能力、运输车速
18、、运距等情况综合考虑，合理配置。运输车装料前彻底清洗干净，车箱底板及周壁涂一层油水混合液(柴油：水分为1：3)，但不在底板留存余液。自卸车箱后挡板卡扣每日保持清洁，易于卡紧、开启，以防汽车在行进过程中漏料，造成材料浪费和路面污染。为了防止下雨对工程造成不良影响，各运输车均备蓬布，一旦遇雨就及时覆盖，以免造成材料浪费和温度散失。沥青混合料的摊铺： 采用摊铺机施工。摊铺前，先对基层面进行调整，透层沥青提前3天喷洒，与其他构造物的接触面上，均匀地刷一薄层沥青，然后放出中线及摊铺边线，并挂标高线以控制各层标高和厚度。摊铺机就位，调整，检测各部位参数及性能，然后按试验路段获得的数据进行作业。 摊铺时，摊
19、铺机始终处于连续工作状态和匀速前进，尽可能避免停机待料现象发生，以确保沥青砼的摊铺质量均匀、平整、连续。摊铺时，混合料的温度控制在110一130的范围内，低温施工时控制在120一140。对外型不规则、路面厚度不同、空间受到限制以及人工构造物接头等摊铺机不能到达的和无法工作的地方，采用人工摊铺。在摊铺过程中，随时检查其宽度、厚度、平整度、路拱及温度，对不合格之处及时予以调整。沥青混合料的碾压：压的机械设备根据拌和站的日产量、摊铺速度及所取得的碾压数据进行组合、配备，双钢轮压路机一台，胶轮压路机一台。碾压时合理掌握碾压温度，压实分初压、复压和终压三个步骤进行，各作业段保持连续进行，各种压路机的碾压
20、次序，碾压遍数通过实验确定，同时各压路机严格按操作规程操作。初压：用双钢轮压路机静压2遍，速度15kmh，初压温度为110130。复压：用三轮压路机碾压1遍，速度为3.5km/h,轮胎压路机碾压2遍，速度为4.0km/h,复压温度控制在90一110之间。终压：用双钢轮压路机静压1遍，速度为3.5km/h,终压温度控制在7090之间。特殊部位碾压：（1）横向接缝碾压：横向接缝的碾压应先用双轮压路机进行横向碾压，碾压带的外侧放置供压路机行驶的垫木，碾压时，压路机位于已压实的混合料层上，碾压新铺层的宽度为15cm。然后每压一遍向新铺混合料移动15-20cm，直至全部压在新铺层上为止，再改为纵向碾压。
21、 （2）弯道或交叉口的碾压：先从弯道内侧或弯道较低一边开始碾压(以利于形成支承边)。对急弯应尽可能采取直线式碾压(即缺角式碾压)，并一转换压道，对缺角处用小型机具压实。压实中应注意，转向同速度要相吻合，尽可能用振动碾压，以减少剪切力。 （3）陡坡碾压：无论是上坡还是下坡，压路机的从动轮始终朝着摊铺方向，即从动轮在前，驱动轮在后(与一般路段碾压时相反)。陡坡碾压时，压路机的起动、停止、变速要平稳，避免速度过高或过低，同时，要求沥青混合料的温度也不宜过高(取压实时温度范围的下限为宜)。 接缝： 在基层的强度达到90以上，就可以进行沥青碎石下面层的施工，施工时，采用半幅施工，首先进行右半幅的摊铺，然
22、后进行碾压，当右半幅摊铺碾压100m时，进行另半幅的施工，调整好熨平板高度，预留压实量，以便压实到相同厚度，趁热用钢轮压路机沿缝碾压最后进行常规碾压。横向接缝施工工艺和纵向接缝相同，在施工过程中，沥青碎石下面层、沥青混凝土上面层的纵向接缝相互错开，形成台阶型，绝对避免上下面层的纵向接缝在同一位置。详见各层接缝位置示意图： 路面各层接缝示意图 沥青砼上面层 沥青砼面层纵向接缝 沥青砼下面层 沥青碎石层纵向接缝 15cm 路中线 气候条件a、在阴雨的天气和未预见的气候突然变化，造成路面滞水时，沥青混合料的摊铺立刻停止。如未经压实即遭雨淋，沥青混合料全部清除，更换新料。b、施工气温低于10时，停止摊
23、铺；当气温下降到15以下时，控制混合料的最大运距，保证碾压温度在规定的范围以内。四、施工进度计划施工工序开工日期完工日期所用天数施工准备6.156.238铺筑6.237.1523五、质量保证措施工程质量是工程之本，为确保工程质量达到优良标准，我们在施工中，将严格执行施工技术规范和操作规程，用健全的质量保证体系，严肃认真的工作态度，力争创造一流的精品工程。1、严格按照设计图纸和技术规范施工，不准偷工减料，弄虚作假，一经发现，立即重处。2、建立以驻地监理、项目部质检科、施工队质检员三级质量检查体系，发现问题及时解决。3、开展劳动竞赛活动，不仅比进度，更要比质量，制定具体的实施细则，加强对每个工序的
24、检测，奖优罚劣。对不合格的工程，坚决返工。4、严把原材料进场关，凡进场材料必须具有有效的产品合格证，必须经中心试验室检测合格方准使用。5、建立“工序质量记录制”每道工序从始至终都要有详细的记录，隐蔽工程要有图像资料，完善技术资料。6、深刻领会设计意图，技术人员对施工人员技术交底，并深入工地，随时解决技术方面存在的问题。7、每天召开一次碰头会，每月召开一次质量分析会，研究解决施工中存在的问题，布置下一步工作目标。8、强化质量意识，加强宣传教育，把工程质量保证意识做到人人皆知，个个自觉把好质量关。七、安全保证措施a) 建立安全体系。项目经理部成立了工地安全组，设专职安全员1名，各个分项负责人负责安
25、全监督，逐级明确安全责任制，责任到人。b) 建立各项安全制度，制定机械、车辆等技术操作规程，开展职工安全教育，奖罚分明，严格执行安全监督，防患于未然，杜绝事故发生。c) 施工现场采用标准化作业。根据指挥部施工中不中断交通的要求，我们采取挂牌施工，在施工地段设警示牌，尽量注意交通安全。以安全为第一，合理组织生产。 the direct punishment 0.5-10,000 yuan, responsible for the direct responsibility for the accident and the responsibility of leadership, such as
