辉绿岩在高速公路沥青路面表面层的应用

Application of Diabase Aggregates Asphalt Mixture on Highway Asphalt Pavement Surface Layer

进行了粗、细集料不同类型组合、不同成型压力、不同旋转压实次数比较等试验,研究了辉绿岩作为高速公路沥青表面层的可行性。

The design and application of diabase asphalt mixture were investigated by different combination of course and fine aggregates, different compaction strength and different gyratory numbers in this paper. Experimental results show that aliabase aggregates can be used for highway pavement surface layer if half diabase fine aggregates can be adopted by lime fine aggregates.
