摘要
SMA沥青混凝土已被广泛地应用到沥青路面结构。本文基于响应曲面法,以玄武岩纤维长度、掺量和油石比为影响因素,以空隙率、矿料间隙率、沥青饱和度、稳定度及流值为响应值,利用中心复合法进行正交组合试验设计,进行标准马歇尔试验。根据试验响应指标建立响应曲面模型进行分析,优化得出玄武岩纤维的最佳长度为6mm,玄武岩纤维的最佳掺量为0.49%,最佳油石比为5.65%。
SMA asphalt concrete has been widely used in asphalt pavement structure.Based on the response surface method,the basalt fiber length,dosage and asphalt-aggregate ratio are taken as the influencing factors,and the void ratio,mineral aggregate void ratio,asphalt saturation,stability and flow value are taken as the response values.The central composite method is used to carry out the orthogonal combination experimental design,and the standard Marshall test is carried out.According to the test response index,the response surface model is established and analyzed.The optimum length of basalt fiber is 6mm,the optimum content of basalt fiber is 0.49%,and the optimum oil-stone ratio is 5.65%.
