高黏改性SMA-13沥青混合料在市政道路中的应用研究

Study on the Application of High Viscosity Modified SMA-13 Asphalt Mixture in Municipal Roads

为了解高黏改性SMA-13沥青混合料在市政道路中的实际应用,论文依托实际工程,选用4%、5%、6%三种不同油石比制备高黏改性SMA-13沥青混合料试件,对其高温抗车辙性、低温抗裂性以及水稳定性进行室内试验检测。试验结果表明,选用5%油石比制备的高黏改性SMA-13沥青混合料具有较高的高温抗车辙性和低温抗裂性。

In order to understand the practical application of high-viscosity modified SMA-13 asphalt mixture in municipal roads,based on the actual project,this paper selected three different oil stone ratios of 4%,5%and 6%to prepare high-viscosity modified SMA-13 asphalt mixture samples,and tested its high temperature rutting resistance,low temperature cracking resistance and water stability in the laboratory.The test results show that the high viscosity modified SMA-13 asphalt mixture prepared with 5%oil stone ratio has higher high temperature rutting resistance and low temperature crack resistance.
