MA103改性沥青混合料在旧水泥混凝土路面加铺中的综合性能研究

摘要

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.%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。
