摘　　要：参照俄罗斯的相关技术规范,为综合平衡沥青的高温与低温性能进行试验研究。通过不同沥青种类的比选,并结合沥青混合料低温抗裂性能的试验验证,提出了寒冷地区浇注式沥青混凝土宜采用聚合物改性沥青或掺加降粘剂的改性沥青作为结合料。In view of the application of the guss asphalt concrete in cold region,some experiments have been done to balance the high and low temperature properties of asphalt according to the related Russian technical specifications.Through the comparison of different kinds of asphalt and the experimental tests of asphalt mixture＇s anti-cracking performance in low temperature,we put forward the method that in cold region we should use the polymer modified asphalt or the thinner modified asphalt as binder in guss asphalt concrete.

关 键 词：浇注式沥青混凝土 聚合物改性沥青 寒冷地区 降粘剂
