摘要
废旧轮胎不仅占用大量的垃圾填埋空间,且容易引发污染,已成为一个严重的环境问题。破碎的废旧轮胎颗粒可以改善沥青混合料的路用性能,采用外掺法制备胶粉沥青混合料试件,经过一系列试验分析,其试验技术指标与路用性能指标均满足规范要求,高温稳定性能和水稳性能良好。
Waste tires not only occupy a large amount of landfill space, but also easily cause pollution, and have become a serious environmental problem. However, the crushed waste tire particles can be used to improve the road performance of asphalt mixtures. This paper used the additive method to prepare rubber powder asphalt mixture specimens. After a series of experimental analysis, the test technical index and road performance index of the specimens met the specification requirements, and the high temperature stability and water stability were good.
