摘要
灌缝胶是用于沥青混凝土路面裂缝修补的常见材料。我国尚无针对沥青混凝土路面灌缝胶的性能评价方法,只能采用沥青三大指标来评价灌缝胶性能,而国外已有完整的灌缝胶试验方法和技术要求。对国内外灌缝胶评价方法进行分析,在此基础上,提出我国沥青混凝土路面灌缝胶评价方法。
Although sealants and fillers, hot-applied, for cracks in asphalt concrete pavements are commonly used, there is no standard specification available for evaluating performance of sealants and fillers in China. Three indices for asphalt to evaluate the performance of sealants and fillers can be used. However, integrated testing methods and technical requirements for sealants exist at abroad. On the basis of the review of evaluating methods for sealants and fillers at home and abroad, the evaluating methods suitable for sealant and fillers in asphalt concrete pavement in China are presented.
