摘　　要：文中以某高速公路工程为例,通过车辙试验、小梁弯曲试验等方法,评价PAC-10和PAC-16双层排水沥青路面的路用性能。试验结果表明,双层排水沥青路面的高温稳定性能、低温抗裂性能以及水稳定性良好,PAC-10和PAC-16试件的动稳定度均达到规范标准,相比之下,PAC-16的路用性能更好,更符合工程施工要求。Taking an expressway project as an example,the road performance of PAC-10 and PAC-16 double-layer drainage asphalt pavement was evaluated by rut test and trabecular bending test.The test results show that the high temperature stability,low temperature crack resistance and water stability of the double-layer drainage asphalt pavement are good,and the dynamic stability of the PAC-10 and PAC-16 specimens can meet the standard.In contrast,the road performance of PAC-16 is better,and can meet the engineering construction requirements.
