摘要
Abstract
At present, aimed at the damage of the cement road surface in many regions of china, a lot of renovation projects are carry out, however reflective crack is the common problem when the asphalt surface layer is added on the old cement road surface. With the material characteristics of high strength and high tenacity, the semi-lexible material witch taken as a stress absorbed layer is used to solve the problem of reflective crack. Therefore, based on the research achievement of cold-recycled technology using foamed asphalt, the semi-flexible material with cement-foamed asphalt has been invented. By comparing two kinds of general cold-recycled mixtures using foamed asphalt, it is found that the semi-flexible material has good physical and mechanical properties, and it can gain better density and the ideal high-performance of load-carrying and toughness and higher shear strength, if it is used as a stress absorbed layer. So the material can reduce the emergence of reflective crack.关键词
