| 摘 要： | 从高模量沥青稳定碎石的材料组成设计出发,通过动态模量和抗压回弹模量两种力学设计参数的测定,研究了高模量沥青稳定碎石的力学性能,通过车辙试验、冻融劈裂试验、劈裂试验及疲劳试验,分析了高模量沥青稳定碎石路用性能.试验结果表明:不同类型沥青对沥青稳定碎石的动态模量影响较大,高模量沥青稳定碎石的抗压回弹模量比普通沥青稳定碎石和改性沥青碎石分别提高了约24%和19%,且高模量沥青稳定碎石具有良好的高温性能、水稳定性能和疲劳性能,但低温性能较差.

| Abstract: | According to the material composition design of high-modulus asphalt treated base(ATB),the mechanical properties were analyzed through measuring their dynamic moduli and compression rebound moduli of high-modulus ATB,modified ATB and conventional ATB,and road service performances were studied through wheel rutting test,freeze-thaw split test,split test and fatigue test.Test result shows that various types of asphalts have relatively great influences on the dynamic moduli of ATBs.The compression rebound modu... |
