影响沥青路面平整度的因素很多,现以盐通高速公路的施工实践为例分析说明。路面摊铺机械及施工工艺的影响摊铺机构参数不稳定、行走装置打滑、机械突然起步和紧急制动以及供料系统速度忽快忽慢等都会造成面层的不平整和局部离析。装有自动找平装置的摊铺机施工时,若以控制高度为主,则采用基准钢丝绳法,若以控制厚度为主,则采用浮动基梁法。一般情况下底面层采用基准钢丝绳
Affect the smoothness of asphalt pavement many factors, now Yantong Expressway construction practice as an example to illustrate. Road paving machinery and construction of the impact of paving instability mechanism parameters, running gear skidding, mechanical sudden start and emergency braking, as well as sudden slow feed system will result in uneven surface and local segregation. Paver equipped with automatic leveling device construction, if the control of the main height, the use of the standard wire rope law, if the control of the thickness of the main, the use of floating beam method. Under normal circumstances the base layer of wire rope
