通过选择 4种不同沥青混合料级配 ,分别采用马歇尔试验和旋转压实试验并采用不同的成型功进行试验 ,以密度、空隙率、吸水率、劈裂强度等指标对沥青混合料性能进行分析、比较、评价 ,寻找有关级配和成型方法对沥青混合料性能的影响程度和影响规律。 By selecting four kinds of asphalt mixture gradation, using Marshall test and rotary compaction test respectively and using different forming work, the properties of asphalt mixture were analyzed by density, porosity, water absorption, splitting strength and other indicators , To compare and evaluate, to find out how and how the gradation and forming methods affect the performance of asphalt mixture.
