高模量沥青混合料贯入强度研究

为研究高模量沥青混合料的抗剪切性能，依托工程中应用的4种高模量添加剂，在室内制备成型高模量沥青混合料试件，进行单轴贯入、无侧限抗压强度和单轴压缩动态模量试验，研究高模量添加剂对黏聚力和内摩擦角的影响规律，系统探究了高模量沥青混合料贯入强度的改善机理，并建立了内摩擦角与贯入强度的相关性模型。

Study on Penetration Strength of High Modulus Asphalt Mixture

In order to study the shear resistance of high modulus asphalt mixture, based on four kinds of high modulus additives currently applied in the engineering, high modulus asphalt mixture specimens have been prepared in laboratory to carry out uniaxial penetration test, unconfined compressive strength test and uniaxial compression dynamic modulus test. The law of influence of high modulus additives on cohesion and internal friction angle has been studied, the high modulus asphalt mixture penetration strength improvement mechanism has been researched systematically and the correlation of internal friction angle and penetration strength model has been established.
