文章针对我国目前尚未有有关沥青路面裂缝热修补材料的性能指标及试验规程的情况,通过借鉴美国SHRP计划、ASTM试验方案及我国的相关试验规范,对四种沥青路面裂缝热修补材料70#普通沥青、道路裂缝专用密封胶、SBS改性沥青、SBR改性沥青的性能指标进行了常规试验测定,通过对试验获得的数据进行对比分析,并根据我国沥青路面气候分区图,提出了道路密封胶、SBS改性沥青、SBR改性沥青等热修补材料在进行沥青路面裂缝修补时的应用区域。
In this paper, according to our country, there are not any relevant performance indexes and test procedures for asphalt pavement crack repair material. By drawing lessons from the American SHRP program, ASTM test program and our country’s relevant test specifications, Asphalt, sealant for road cracks, SBS modified asphalt, SBR modified asphalt performance of the conventional test determination, by comparing the data obtained from the test, and according to China’s asphalt pavement climate zoning map, put forward the road sealant , SBS modified asphalt, SBR modified asphalt and other thermal repair materials in the repair of asphalt pavement cracks when the application area.
