摘　　要：采用两种改性树脂配方作为混合料的结合料,分别测试了结合料的密度,选择适合路面修补的混合料级配,并通过马歇尔试验进行了配合比设计,确定了最佳沥青用量,研究了不同温度条件下冷拌混合料强度随时间的增长情况,总结了这种改性树脂结合料冷拌混合料的强度行程规律。Two kinds of modified resin were used as the material of the mixture, and the density of the material was tested. The gradation of as-phalt mixture is selected, and the optimum asphalt content is determined by the Marshall test method. The strength of cold mix at different tem-peratures was studied. The strength of this kind of modified resin with cold and mixed materials is summarized.

关 键 词：改性树脂结合料 路面修补 冷拌混合料 强度增长
