摘　　要：沥青混合料体积特性直接影响其力学性能与使用性能,但混合料级配、材料密度、设计方法等因素也直接影响沥青混合料的体积特性。本文对当前沥青混合料体积设计方法进行了分析,从多方面对CAVF法、Superpave法、马歇尔法等方法所设计的沥青混合料性能与体积特性进行了评价,并提出了用旋转压实仪复核其他方法所设计级配稳定性的建议。Mechanics and pavement use performance of asphalt mixture is directly influenced by volume characteristic which is also directly influenced by other factors such as gradation of mixture,density of material,design method.This paper has analyzed some design methods on asphalt mixture,and evaluated performance and volume characteristic of asphalt mixtures which were designed by CAVF method,Superpave method and Marshall method.It is suggested that gyral compactor shoud be used to check the stability of gradation designed with other methods.
