摘要
为了对沥青混合料Superpave与马歇尔设计方法进行比较和分析,采用Superpave方法成型旋转压实试件,进行混合料设计,确定混合料级配和沥青用量,再按照确定的级配制作马歇尔试件,获取2种方法的体积指标以进行对比。结果表明:Superpave及马歇尔设计方法2种指标具有良好的对应关系,可在进一步应用中继续进行对比分析。
In order to compare and analyze Superpave and Marshall design method for asphalt mixture,spin test model is made with Superpave. The mixture design is carried out to determine proportion for mixture and amount of asphalt. The Marshall model is made according to proportion determined. The volume indexes of both methods are acquired to do the comparison. The result shows that the indexes are of nice matching relationship, which should be kept analyzing.
