沥青混凝土路面施工是高等级公路工程施工中的一道主要程序,也是直接反映沥青混凝土路面工程质量成果并使其具备长久使用年限的最后一道工序。实际施工中,离析不仅是沥青混凝土路面最常见的近期病害,也是沥青混凝土路面在今后使用年限内引发诸如裂缝、麻面、脱皮、坑槽等远期病害的根源。为了提高施工水平、提高产品质量,从沥青混凝土路面施工的生产流程出发,探究离析的成因,提出施工中前场和后场的工艺控制及质量管理的各个环节要点,对现场施工具有一定的指导作用。
Asphalt concrete pavement construction is a high-grade highway construction in a major program, but also directly reflect the asphalt concrete pavement engineering quality results and make it with the long-term service life of the last process. In actual construction, segregation is not only the most common recent disease in asphalt concrete pavement, but also the root cause of long-term diseases such as cracks, pockmarks, peeling and pit in asphalt concrete pavement in the future service life. In order to improve the construction level and improve the quality of products, starting from the production process of asphalt concrete pavement construction, explore the causes of segregation, put forward the key points of process control and quality management of front and back yard during construction, and have some guidance to on-site construction effect.
