摘要
以AC-13型再生沥青混合料为研究对象,采用马歇尔设计方法确定出热拌再生沥青混合料级配与新沥青掺量,其中RAP料掺量为30%、最佳油石比为3.7%;再以成型试件的空隙率基本相等为原则,确定出表面活性类温拌再生沥青混合料的拌和与成型温度依次为135℃与130℃。
AC- 13 recycled asphalt mixture was studied in the paper. The gradation and new asphalt content of hot recycled asphalt mixture were determined by Marshall mix design method, and the content of RAP material is 30%, the optimum asphalt ratio is 3.7%; Then the mixing and molding temperature of warm recycled asphalt mix with surfactants category were set out based on the principles of the porosity of molded specimens funda - mentally equal, they were 135 ℃ and 130 ℃.
