摘　　要：制备了一种钢桥面铺装用聚合物合金材料,考察了热塑性弹性体、增韧树脂、硬质沥青及无机填料对其拉伸性能的影响,测试了较佳配方聚合物合金及其铺装结构“下面层聚合物合金+上面层高弹改性沥青混合料SMA10”的路用性能。结果表明,聚合物合金的较佳配方为:35%热塑性弹性体+70%增韧树脂+60%硬质沥青+35%无机填料,此时聚合物合金材料具有较佳的综合性能。聚合物合金铺装结构具有良好的粘结性能和高温性能,且铺装层厚度对其高温性能影响较大。A polymer alloy material for steel deck pavement was prepared.The effects of thermoplastic elastomer,toughened resin,hard asphalt and inorganic filler on its tensile performance were investigated.And then the better formula was further optimized.Furthermore,the pavement performance of polymer alloy and its pavement structure“polymer alloy+high-elasticity modified asphalt mixture SMA10”were tested.The results showed that the better formula of ploymer alloy was 35%thermoplastic elastomer,70%toughened resin,60%hard asphalt and 35%inorganic filler.Polymer alloy pavement structure had good bonding and high-temperature performance,and pavement layer thickness had great effect on its high-temperature performance.
