内容摘要
根据滑县2009年乡道建设项目第六标段Y026枣村乡东姜庄—枣村乡S101公路,结合业主汇编施工招标第六合同段主要技术资料、公路工程施工技术规范要求、检验评定标准、标准的质量管理体系、公司目前的施工队伍及技术和设备状况、并现场考察所了解到的实际情况。统筹考虑了全合同段的施工工艺,现场布置及施工进度计划。合理组织冷再生施工新工艺,做到旧沥青路合理利用,减少劳动强度,节约土地资源、节省工程施工时间、提高自然环境保护。

引言
沥青路面就地冷再生,适用于一、二、三、四级公路沥青路面的冷再生利用,沥青路面就地冷再生分为沥青层就地冷再生和全深式就地冷再生两种方式。对于一、二级公路,再生层可作为下面层、基层;对于三、四级公路,再生层可作为面层、基层,用作上面层时应采用稀浆封层、碎石封层、微表处等做上封层。沥青层就地冷再生应使用乳化沥青、泡沫沥青作为再生结合料;全深式就地冷再生既可使用乳化沥青、泡沫沥青等沥青类的再生结合料,也可以使用水泥、石灰等到无机结合料作为结合料。当使用水泥、石灰等作为再生结合料时,再生层只可作为基层。本论文就
是农村公路四级乡道旧沥青路改造就地冷再生作为基层进行施工的。
目前农村公路改造工程的全面实施,为公路工程新技术、新工艺的推广应用提供了广阔天地,公路冷再生技术中农村公路旧沥青路改造工程取得初步成功的一种新型施工工艺。施工工艺采用公路冷再生机械施工,对沥青路面进行现场冷铣刨,破碎,掺入一定数量的新集料、活性填料(水泥、石灰等)水,经过常温拌和、摊铺、碾压等工序,一次性实现旧沥青路面再生的技术。旧沥青层连同旧石灰稳定土一起拌和,作为路面基层的一种新型工艺。它具有原料易得,整体性好,刚度和承载力大,水稳性及抗冻性好,且随着时间的延伸其强度也不断增长的特点。
