摘要
选择合理的级配对橡胶沥青混凝土抵抗高温及重载交通具有重要意义,但针对橡胶沥青混凝土路用性能的级配选择国内尚缺乏系统研究。文章针对两种有代表性的橡胶沥青混合料(AR-AC13与AR-SMA13)进行水稳定性试验、车辙试验、动态回弹模量试验与疲劳试验,对比其路用性能。试验研究表明:AR-AC13与AR-SMA13水稳定性相当,AR-SMA13高温稳定性稍好,AR-AC13低温抗裂性能和抗疲劳性能更优,但造价偏高。
It is significant to choose the reasonable gradation for Asphalt rubber mlxea concrete to resist the high temperature and heavy traffic, but at present, the appropriate gradation choice of asphalt rubber for the stability of high temperature still lacks the systematic research in our domestic. This article mainly makes a comparative study for two kinds of representative asphalt rubber mixtures （AR-AC13 and AR-SMA13） by making the water stability, wheel tract test, dynamic elastic modulus test and fatigue test to comparing their different pavement performance, and finally to approval that AR-AC13 are well- matched in the aspect of water stability performance with AR-SMA 13, poorer high-temperature performance, but much better in the aspect of low-temperature performance and fatigue resistance while along with the higher cost.
