摘要
阐述了采用SHRP实验设备及评价方法,对旧沥青混凝土路面中的老化沥青及两种旧料掺配率较高的再生沥青进行了低温性能的对比实验,在得出较高的旧料掺配率情况下,再生沥青蠕变劲度及速率的变化规律及旧料掺配率对于再生沥青低温性能的影响。
SHRP testing apparatus and evaluating method are adopted to test the low temperature performance of weathered asphalt （taken from old road pavement） and of two kinds of reactivated asphalt （mixed with more old materials）. The change regularity of creep intensity and creep speed of reactivated asphalt with more old material addition and the influence of high old material adding rate on low temperature performance of reactivated asphalt are found out.
