摘要
对一种Superpave级配沥青混合料不同空隙率的试样进行了不同温度、不同加载频率条件下动态模量试验,分析了混合料动态模量随体积参数、加载条件的变化规律,研究结果对我国的路面设计模量动态参数的选择具有借鉴意义。
Dynamic modulus (E^*) tests are performed on various void volume samples under the conditions of various temperatures and various loading frequencies, which are obtained from asphalt mixtures with Superpave gradation, and the changing regularity of dynamic modulus of asphalt mixtures with the volume parameters and loading condition is analyzed. The results offer some reference to modulus selection during the pavement design.
