| 摘 要： | 试验采用相同的集料调配成2种不同的级配，比较不同级配下，橡胶沥青混合料路用性能的差别，结果表明：AR—ACl3橡胶沥青混合料更适于间断级配及开级配，其关键筛孔为0．075mm筛孔，降低此筛孔通过率将导致沥青用量增加，进而影响了其高温稳定性。尽管橡胶沥青混合料需要较大空间来容纳橡胶粉，存在一个较佳级配来满足其密实性要求。

| Abstract: | In the experiment, the same aggregate deployment into two different gradations, com- pared with the next, rubber bituminous mixture performance differences. The results show that：AR-AC13 rubber asphalt mixture is more suitable for the continuous gradation and open gradation, its key screen hole is 0. 075 mm screen hole, reduce this screen hole passing will lead to increased asphalt content, af- fecting the their high temperature stability. Although rubber asphalt mixture need larger space to accom- modate rubber powder, the gap is not the bigger the better, there is a better match level to meet its densi- ty of requirements. |
