摘要

为改善橡胶沥青混合料的高温性能，提出以橡胶沥青胶浆和矿料级配为主要研究对象的优化思路。通过室内试验，首先研究粉胶比对橡胶沥青胶浆抗车辙因子和相位角的影响；然后结合橡胶沥青的特异性，对其橡胶沥青混合料的矿料级配进行选择和调整，将动稳定度和相对变形作为混合料高温性能评价指标，得出优化后的矿料级配。研究结果表明，提高橡胶沥青混合料高温稳定性的措施有：适当调整粉胶比，控制在1.2左右为宜；以水泥取代矿粉作为混合料的填料；以传统SMA级配为基础，对混合料级配作出调整，适当降低填料比例，能够实现橡胶沥青混合料高温稳定性的优化。

Abstract

To improve the performance of asphalt rubber mixture under high temperature

an optimal proposal was put forward which selected asphalt rubber mortar and aggregate gradation as the main objects. According to experimental tests

the anti rutting factors and phase angles of asphalt mortar was studied with different rations of filler bitumen. And then

with the characteristics of asphalt rubber

the optimal gradation was presented by means of the adjustment of aggregate gradation which chose dynamic stability and relative deformation as value indexes. The results shew that asphalt rubber mixtures would show an optimal high temperature performance if the following measures can be taken: (1) making an adjustment of ratio of filler bitumen to about 1.2; (2) replacing mineral powder with cement; (3) making an adjustment of aggregate gradation and lower the proportion of mineral powder based on SMA.
