采用体积法进行密级配大粒径沥青混合料LSM-30级配设计,分析大粒径密级配沥青混合料LSM-30的级配组成特点,并分别采用振动成型和大型马歇尔击实方法对混合料的强度性能、水稳定性及低温拉伸性能及塑性指标等进行对比试验,探讨成型方法对LSM性能的影响程度和规律。
Using the volumetric method, the density gradation LSM-30 grading design of large-size asphalt mixture was used to analyze the gradation composition characteristics of the large-size dense graded asphalt mixture LSM-30. The effects of vibration molding and large Marshall compaction on the mixing Material strength, water stability and low temperature tensile properties and plasticity indicators were compared to test the impact of molding methods on the performance of the LSM rules.
