摘　　要：多孔玄武岩其吸水率较大,同样吸收沥青也较大,从而对混合料配合比设计、质量控制和使用性能都产生很大的影响。采用马歇尔法和SUPERPAVE旋转压实仪法对多孔玄武岩进行设计,两种方法设计的最佳沥青含量、混合料理论最大相对密度和矿料间隙率均差别较大。采用马歇尔法对混合料进行设计和现场控制时,应参照SUPERPAVE的设计数据。Porous basalt has high water absorption and high asphalt absorption, so it can was af fected that design, quality control and using performance of the mixture. It was very different, that optimized asphalt content （OAC） and volume index of porous basalt aggregate mixture were designed by Marshall method and Superpave method. Also, the theoretical maximum density and VMA of mix ture bring on two design methods were compared. Then through the analysis and contrast, the quality of porous basalt aggregate mixture can be better controlled by Marshall method.
