车辙是正交异性钢桥面沥青混凝土铺装主要病害之一 .采用汉堡轮辙试验机 ,提出了适宜于德国、考察浇注式沥青混合料高温性能的试验条件 ,测试和比较了不同浇注式沥青混合料的高温性能 .聚合物改性沥青混合料具有较高的抗车辙能力 .滞留时间和拌和频率对浇注式沥青混合料的性能有明显的影响
Rutting is one of the main diseases of asphalt concrete pavement of orthotropic steel bridge deck.The test conditions of high temperature performance of pouring asphalt mixture suitable for Germany were put forward by using Hamburg rutting test machine.Testing and comparing different pouring asphalt The high temperature performance of the mixture.The polymer modified asphalt mixture has a higher rutting resistance.The residence time and mixing frequency have a significant impact on the performance of pouring asphalt mixture
