橡胶沥青混合料级配范围的探讨

国内外不同地区橡胶沥青混合料设计级配范围有着较大的差异。为了确定合理的级配范围,该文应用三种级配理论模型,通过关键筛孔通过率的控制,确定了橡胶沥青混合料的理论级配,并分析了关键筛孔通过率对橡胶沥青混合料路用性能的影响。

Discussion on Gradation Range of Rubber Asphalt Mixture

There are great differences in the design gradation range of rubber asphalt mixture in the different areas at home and abroad.To determine the reasonable gradation range,this paper uses three gradation theoretical models.The paper determines the theoretical gradation of rubber asphalt mixture by controlling the key sieve passage,and analyzes the influence of the key sieve passage on the using performance of rubber asphalt mixture.
