摘要
同步碎石封层技术是路面养护技术中一项新的技术。通过拉拔试验,对比分析橡胶沥青碎石封层、SBS改性沥青碎石封层、SBR改性乳化沥青碎石封层的感温性能。研究结果表明:橡胶沥青碎石封层有着良好的温度敏感性,这是因为经胶粉改性后,沥青的感温性得到了改善。
Synchronous chip sealing technology is one of the new technologies of the pavement mainten-ance.According to pull-off tests,this paper compares and analyzes the sensitivity for temperature of rubber as-phalt seal coat gravel,SBS modified asphalt seal coat gravel and SBR modified asphalt emulsion seal coat gravel.The results show that rubber asphalt seal coat gravel has favorable sensitivity for temperature because the sensitivity for temperature of asphalt is improved through being modified by rubber powder.
