摘要
为了更科学的对沥青混合料的水稳定特性进行评价,基于我国现行规范的试验方法,分别通过冻融劈裂与浸水马歇尔对比试验,对不同类型沥青混合料试件的水稳定性进行了研究分析.研究表明,利用残余模数对沥青混合料水稳定性进行评价是科学可行的.基于本文研究成果,推荐残余模数阀值采用0.85.
Aiming at the deficiency of bituminous mixtures water stability estimate method in present specifications in China,the water stability of multitype bituminous mixtures test pieces was analyzed by comparing freezing and thawing split tensile tests with immersion Marshall stability tests.Residual modulus is brought up to appraise the water stability of bituminous mixtures,and the residual modulus valve 0.85 was recommended.
