摘　　要：采用MA103沥青增强改性剂制备出改性AC-13沥青混合料,并成型组合式试件,通过车辙试验、疲劳试验对MA103改性AC-13沥青混合料的路用性能进行评价,与传统的几种沥青加铺层进行了路用性能和经济性对比分析,并通过泰兴市旧水泥混凝土路面加铺改造工程对MA103改性AC-13沥青混合料用于沥青加铺层的可行性进行了验证。结果表明:MA103改性AC-13沥青混合料较传统的沥青加铺层具有优异的抗车辙性能、疲劳性能和经济性,用于旧水泥混凝土路面加铺层材料是完全可行的。The modified AC-13 asphalt mixtures were prepared with enhanced modifier MA103, and then the com- bined specimens were molded. The pavement performance of MA103 modified AC-13 asphalt mixtures was evaluated by rutting test and fatigue test, and the pavement performance and economy of MA103 modified AC-13 asphalt mix- tures was compared with several traditional asphalt mixture overlays. The feasibility of MA103 modified AC-13 as- phalt mixtures were verified though old concrete pavement overlaying projects in the city of Taixing. It is found that MA103 modified AC-13 asphalt mixtures have superb anti--rutting performance, fatigue performance and economy. It is completely feasible for MA103 modified AC-13 asphalt mixtures to be used in old concrete pavement overlaying.
