摘要： 本文研究了Superpave不同公称最大粒径混合料马氏击实次数与吸水率、密度、孔隙率等体积特性的关系，得出了获取4.0％孔隙率的标准马氏击实次数；并对水损害试验击实标准进行了讨论，建议采用双面击实40次成型马氏试件来进行水损害检验。

Abstract: The relationship between beat numbers of Marshall and volumetric properties such as percent of absorbed water, density, and volume of air etc with different Nominal Maximum Sieve Size of Superpave Asphalt Mixture was researched in this paper. And the beat number of Marshall to acquire the volume of air with 4.0 percent was ascertained too. We also discussed the beat criterion of the test of moisture damage, and suggest that we can use 40 times beat of each Marshal specimen side to acquire the volume of air with 7.0 percent and to test the property of anti moisture damage of mixture.
