摘要
分析了传统沥青混凝土(AC)、多碎石沥青混凝土(SAC)、沥青玛蹄脂碎石混合料(SMA)、大粒径沥青混合料(LSAM )和开级配摩阻层路面(OGFC)等新型高等级公路沥青面层结构类型和实用性,结果表明:较密级配沥青混合料具有更好的路用性能,可以改善沥青路面使用品质,延长使用寿命,具有较好的经济效益和社会效益。
The structures and the practicability of some new pavements, such as AC, SAC, SMA, LSAM and OGFC, have been introduced in this paper. The results indicated that the pavement performances of the dense graded asphalt concretes are superior to the conventional one and its life circle has been prolonged. The economical and social benefit will also be increased by this method.
