摘　　要：该文介绍了在原材料各项指标合格的前提下,特别是沥青的动力粘度有较高的要求时,对排水沥青混合料进行设计,其空隙率、连通空隙率等指标应满足要求。各项准备工作完成后进行排水路面试铺工作,并对两种碾压方案作了对比。然后对试验路进行了检测,各项指标满足行车要求。Under the premise of various indexes of raw material being checked out, especially the dynamic viscosity of asphalt being higher required, the drainage asphalt mixture can be designed. Its indexes of voidage, connected voidage and so on must meet the requirements. After all preparation works are done well, the test paving work of the drainage pavement are started. And two schemes of rolling are compared, and then the test road is inspected. All indexes meet the driving demands.
