摘　　要：系统比较分析ARAC-20橡胶沥青混合料与AC-20改性沥青混合料的路用性能。采用直道加速加载试验研究不同厚度ARAC-20与AC-20抗裂性能;采用MTS进行疲劳试验研究2种沥青混合料的抗疲劳性能;采用马歇尔试验及冻融劈裂试验研究2种沥青混合料的水稳定性等。结果表明,相对AC-20改性沥青混合料而言,ARAC-20橡胶沥青混合料具有更好的抗裂性、水稳性和耐疲劳等性能。The comparison of the performance of ARAC-20 rubber asphalt mixture with AC-20 modified asphalt mixture was conducted. The antifatigue performance of ARAC-20 and AC-20 with different thicknesses was studied by straight-track accelerated loading test. The fatigue properties of two kinds of asphalt mixtures were studied by MTS. Two kinds of asphalt mixtures were studied by Marshall test and freeze-thaw splitting test on water stability,etc. The results show that ARAC-20 rubber asphalt mixture has better crack resistance, water stability and fatigue resistance than AC-20 modified asphalt mixture.
