摘　　要：利用直线式加速加载试验系统,对12种沥青铺装方案进行了大型直道足尺试验。研究了正交异性钢桥面板的受力特点和动荷载作用下的响应特性,分析了导致钢桥面沥青铺装层产生疲劳破坏形式的原因,指出了现行钢桥面沥青铺装设计存在的主要问题,并针对目前钢桥面沥青铺装设计提出建议。Using the Linear Track Accelerated Loading Facility System,12 types of direct track fullscale tests of asphalt pavement are carried out.The stress and response characteristics of the orthotropic bridge deck under dynamic load are discussed in this paper.And the causes that result in the two types of fatigue failure of the asphalt pavement are obtained through analyzing the results of the linear track fullscale test.In addition,the main problems in the nowadays design of asphalt pavement on steel bridge deck are presented and the suggestion to asphalt pavement design is given.
