通过汉堡轮辙试验 ,考察了浇注式沥青混合料的抗车辙能力 ,硬沥青浇注式沥青混合料具有良好的抗车辙能力 .通过低温弯曲试验和逐步降温的钢桥面铺装复合结构疲劳试验 ,测试与比较了使用硬沥青的浇注式混合料低温抗裂性能 .高性能聚合物改性沥青浇注式混合料具有较长的疲劳寿命和较低的断裂温度 ,可用于钢桥面浇注式沥青铺装 .
The wheel tracking test in Hamburg investigated the anti-rutting ability of pouring asphalt mixture, and the hard asphalt pouring asphalt mixture has good anti-rutting ability.Through the low temperature bending test and the gradual cooling fatigue test of the steel deck pavement composite structure, Test and compare the low-temperature crack resistance of cast-in-situ asphalt mixture with high-strength asphalt.The high-performance polymer modified asphalt cast compound has long fatigue life and low fracture temperature, which can be used in cast-in-place asphalt pavement Loaded
