德国产Duroflex~新型沥青混凝土添加剂在我国公路路面上的应用

Application of New Type Asphalt Concrete Additive——Duroflex~ Produced in Germany in Highway Pavement of China

通过高强度沥青添加剂DuroflexR改性后的沥青混合料,具有抗高温车辙、低温抗裂、防止水害以及耐久性等方面的优势,远远超过聚合物改性沥青和SMA结构的路面性能,而工程总造价却远远低于同类产品的30%以上,可广泛用于高等级公路、重交通道路等的新建、大修以及养护等路面工程。

The asphalt mixture modified by high strong bituminous additive--DuroflexR can improve the performance of high-temperature stability,reduce the low-temperature cracking,prevent flood damage and have good durability with the engineering cost of 30% lower than similar products,which preponderate over the pavement performance of polymer modified asphalt and SMA pavement. So it can be widely used in the new construction,heavy repair and maintenance of pavement engineering in roads of high class and heavy traffic roads.
