摘要
针对市场上普通改性沥青无法适应"超重载交通道路",混凝土桥面在多雨、重载等综合条件下水损害严重,以及钢桥面铺装中存在车辙、疲劳开裂等问题,从沥青角度出发,创造性地开发出重载交通专用改性沥青、混凝土桥面改性沥青以及高弹性改性沥青,成功解决路面铺装中超重载、疲劳开裂等问题。
Aiming at the plain modified asphalt of market hard to suit the 'over-heavy load traffic road',the concrete deck is seriously damaged by the rainwater and heavy load, and there are problems of rutting and fatigue cracking in the pavement of steel deck. From the asphalt angle, it is innovatively to develop the special modified asphalt, concrete deck modified asphalt and high elastic modified asphalt of heavy load traffic so as to successfully solve the problems of over-heavy load and fatigue cracking in the pavement construction.
