| 摘 要： | 在沥青路面结构层内设置多孔隙沥青稳定碎石排水层，可以迅速排出渗入结构层内部的自由水。但排水层本身可能较长时间处于水浸湿状态下，在水的浸泡及车辆荷载的作用下可能会发生水损坏。所以，排水性沥青稳定碎石应具有水稳定性。本文经对三种开级配的沥青稳定碎石进行了试验研究，得出ATPB的沥青用量应在2．5％以上，空隙率在18％以上的结论。

| Abstract: | Setting asphalt treated permeable base material structure in the asphalt pavement layer may discharge the free water in the interior mad structure rapidly. But the internal drainage layer may be under the moist condition for a long time. It could possibly cause water damage to the roads. Therefore, the asphalt treated permeable base should have the property of water stabihty. Based on the experiment results on three kinds of open graded ATPB, it is concluded that asphalt content should be above 2.5% and porosity should be above 18%. |
