摘　　要：通过对集料孔隙率、孔径尺寸与集料沥青吸收关系以及沥青被集料吸收可能引起的后果分析,指出考虑沥青被集料吸收对沥青混合料空隙率影响的重要性。根据沥青被集料表面孔隙吸收时的分布状态,分析总结了在混合料设计时最大理论相对密度的计算方法以及在工程实际中沥青混合料的毛体积测定方法。Through the analysis of the relationship between aggregate porosity,pore size and the asphalt absorption and its possible consequences caused by the asphalt absorption from aggregates,it is indicated that it is essential to consider the influence of asphalt absorption on the porosity of asphalt mixture.According to the distribution of asphalt when it is absorbed by the surface pores of aggregate,the calculation method of maximum theoretical relative density and the measurement method of gross volume of asphalt mixture in engineering practice are analyzed and summarized.
