旧沥青路面材料回收的试验分析

Test and analysis of reclaimed mixture for old asphalt pavement

对回收沥青混合料与回收沥青进行了试验分析,并且采用马歇尔试验方法确定了再生沥青混合料的最佳用油量。大量室内试验结果表明通过添加再生剂、原材料,旧沥青路面材料可以再生利用。

The reclaimed asphalt mixture and reclaimed asphalt are tested and analyzed. The optimum as- phalt content of recycled asphalt mixture by Marshall is obtainted. The test results show that the mixture for old asphalt pavement may be recycled by adding recycling agent and raw material.
