温拌高模量沥青混合料设计与性能研究

Study on Design and Performance of Warm-mixed High-modulus Asphalt Mixture

基于温拌沥青技术与高模量沥青技术,研发了一种温拌高模量沥青混合料,并对该种沥青最佳拌合温度、路用性能、动态和静态模量进行了测试评价。结果表明,温拌高模量沥青混合料拌合温度比常规高模量沥青混合料低30℃以上,并具有良好的高温抗车辙能力和水稳定性。

A warm-mixed high-modulus asphalt mixture is developed based on warm-mixed asphalt and high-modulus asphalt technology. The optimum mixing temperature, pavement performance, dynamic and static modulus of this mixture are tested and evaluated. The test results show that the mixing temperature of the warm-mixed high-modulus asphalt mixture is lower 300 C than that of conventional high-modulus asphalt mixture. Moreover, this asphalt mixture has the good high temperature rutting resistance and water stability.
