为降低SMA造价,采用石灰岩与基质沥青配制SMA沥青混合料,并通过对玄武岩、石灰岩、基质沥青、改性沥青进行不同组合配置SMA沥青混合料,采用马歇尔成型方式进行沥青混合料的成型,并采用车辙试验、浸水马歇尔试验对不同组合SMA沥青混合料的高温性能和水稳定性进行对比,在室内试验基础上,进行试验段铺筑。室内试验以及试验路段检测表明,石灰岩与基质沥青配制的SMA沥青混合料的路用性能完全可以满足现行规范要求,具有较好的路用性能及经济性。 In order to reduce the cost of SMA, SMA asphalt mixture was prepared by limestone and matrix asphalt, SMA asphalt mixture was prepared by different combinations of basalt, limestone, matrix asphalt and modified asphalt, and the asphalt mixture was formed by Marshall forming method Using rutting test and immersion Marshall test, the high temperature performance and water stability of different combinations of SMA asphalt mixture were compared. Based on the laboratory test, the test section was paved. Laboratory tests and testing of test sections show that the road performance of SMA asphalt mixture formulated with limestone and matrix asphalt can fully meet the requirements of current codes and has good road performance and economy.
