为提高沥青路面高温抗车辙、低温抗开裂的能力,近年来国内有关部门采取了许多技术措施,如使用各种改性沥青、SMA面层以及矿料级配调整等,同时还从国外引进了钢纤维或聚酯纤维等化学加筋材料,掺入到沥青混凝土混合料中,形成加筋沥青混凝土面层,用于等级较高的交通土建当中。 In order to improve the high temperature rutting resistance and low temperature cracking resistance of asphalt pavement, many technical measures have been taken in recent years, such as the use of various ffdiping.37ix.com.cn fddiping.37ix.com.cnwendingji.37ix.com.cnzuranji.37ix.com.cnfangwuji.37ix.com.cn guangliangj.37ix.com.cnmodified asphalt, SMA surface layer and the gradation adjustment of mineral aggregates. At the same time, chemical reinforced materials such as steel fibers or polyester fibers have been introduced from abroad and mixed into asphalt concrete mixtures to form reinforced asphalt concrete surface layer for grade comparison.
