大粒径沥青排水层施工控制

Construction control of Large Size Porous asphalt Mixture permeable course

从LSPM施工前的准备工作入手,详细介绍了大粒径沥青排水层施工工艺,具体包括沥青混合料的运输、摊铺、压实及接缝处理等,提出了减少沥青混合料离析的措施,从而加快工程进度,保证工程质量。

Stating from the preparation work of Large Size Porous asphalt Mixture （LSPM） the construction technology of permeable course with large stone porous asphalt mixture is introduced in detail, which includes the transportation, spreading, rolling, joint treatment and other aspects of asphalt mixture. At the same time measures are proposed to prevent the segregation of asphalt mixture in order to speed up progress and ensure engineering quality.
