摘　　要：介绍润扬大桥钢桥面铺装试验桥的方案设计、试验研究、温度测试、交通量调查和使用性能跟踪观测,通过混合料高温车辙试验、低温弯曲试验、复合梁疲劳试验以及拉拔试验等分析实桥试验沥青混合料基本性能,阐述铺装内各层温度梯度分布规律及与大气温度变化关系,通过使用性能跟踪观测介绍浇注式沥青混凝土+环氧沥青混凝土新型铺装结构的工程效果。The trail bridge design,the mixture performance test,the temperature between the different layers of the deck surfacing,the traffic investigation and the surface performance observation are introduced in this article.The basic performance of the mixture used in the trial bridge is analyzed through rutting tests at high temperature,bending tests at low temperature,fatigue tests of the composite beam and pull off tests.The rule of the temperature gradient distribution in the pavement and the variety relation with the air temperature are described by the chart.The engineering effect of the new structure of deck surfacing as'gussasphalt+epoxy asphalt'is presented through the observation of the performance such as rut,crack and non-skid quality.
