摘　　要：针对我国规范中沥青混合料动稳定度标准的不足,结合四川省气候条件制定不同分区沥青混合料的容许动稳定度。首先根据四川省的地形与气温条件,提出沥青路面车辙气候分区;选用沥青混合料车辙预估模型,提出沥青混合料容许动稳定度的确定方法;推荐了四川省不同分区不同沥青面层的动稳定度容许值,为更为合理地设计沥青混合料以控制路面车辙提供参考。Rutting is one of the main failure modes in pavement structures subjected to mechanical loading. The current rutting standards of Wheel Tacking Testers （WTT） were not suitable well in Sichuan province for the multiple climate partitions. Climate partitions were redistricted in Sichuan province based on the difference of terrain and temperature. Base on the WTT and mechanical data derivation, a rutting prediction model of asphalt mixture was built as well as the method of allowable dynamic stability was derived. The allowable dynamic stability indexes were proposed based on the different pavement layer in Sichuan province. The proposed indexes and prediction model can provide a reference for asphalt mixture design for rutting prevention.
