| 摘 要： | 对低标号沥青、70号普通道路石油沥青和SBS改性沥青进行了沥青混合料性能试验,并对试验结果进行了对比分析.结果表明,三种不同类型的低标号沥青混合料均满足高温动稳定度、水稳定性、冻融劈裂以及低温抗裂性能的规范要求,其中低标号沥青混合料的高温稳定性能还与SBS改性沥青较为接近.并根据试验结果确定了低标号沥青的适用区域和层位,为低标号沥青的推广和运用提供了科学依据.

| Abstract: | The performance of low grade asphalt mixture, 70# ordinary road petroleum asphalt and SBS modified asphalt mixture are contrastively tested and studied. The results show that, the three different types of low grade asphalt mixture can meet the specification requirement of the high dynamic stability, water stability, freeze-thaw splitting and low-temperature anti-cracking performance, and the high temperature stability of low grade asphalt is close to the SBS modified asphalt. This paper also analyzes the applicable region and position of low grade asphalt mixture according to the test results, providing theoretical basis for the application of low grade asphalt on highway construction. |
