沥青混凝土路面裂缝修补材料填封后,在交通荷载及外界环境的综合影响下,受力形式比较复杂。研究试验模拟了裂缝修补材料受力的最主要两种形式,拉伸与剪切两种受力情况,在参考了大量的文献资料和对相关养护部门调查的基础上,试验选择了两种较典型的裂缝宽度和3种填缝材料,主要研究低温条件下几种不同修补材料的修补效果,力求寻找一种有效提高季冻区沥青混凝土路面裂缝修补耐久性的材料。
Asphalt pavement crack repair material filling, under the combined effect of traffic load and the external environment, the form of stress is more complicated. The research test simulates the two main forms of the force of the crack repair material, the two kinds of stress conditions of tension and shear. Based on a large amount of references and the investigation of relevant maintenance department, The typical crack width and three kinds of caulking materials are mainly studied the repair effect of several different repaired materials under low temperature conditions and strive to find a material that can effectively improve the durability of asphalt pavement cracks repair in seasonal frost area.
