高粘度基质沥青混合料力学性能研究

Research on dynamic performance of high viscosity medium asphalt mixture

通过对高粘度基质沥青(AH-30)、重交通沥青(AH-70)、SBS改性沥青及其混合料力学性能进行全面的对比试验研究,结果表明高粘度基质沥青混合料在抗压强度、抗压回弹模量、劈裂强度上均比普通重交通沥青有很大的提高,也比一般的改性沥青混合料要好。

The paper undertakes the comprehensive experimental research on high viscosity medium asphalt（AH-30）,the heavy traffic asphalt（AH-70）,SBS modified asphalt and its mixture＇s dynamic performance,and proves by the results that the high viscosity medium asphalt mixture is higher than the common heavy traffic asphalt in the aspects of compressive strength,the modulus of resilience,and the cleavage strength,and it is better than the general modified asphalt mixture.
