【摘要】 对SMA混合料填入不同剂量的水泥代替部分矿粉,做成6组其他成分均相同的试件,分别做马歇尔和浸水马歇尔及车辙试验,分别用二次曲线和直线回归分析马歇尔稳定度和残留稳定度及动稳定度与水泥含量之间的关系,确定最佳水泥用量,从而提供一种确定SMA最佳水泥用量的方法。更多还原

【Abstract】 This paper introduced a method to determine the optimum dose of cement to substitute for a part of mineral dust in SMA mixture. Six samples,which have different cement contents,have been made Marshall test and immersion Marshall test and Rutting test. According to conic section and liner regression analysis,we attained the relationship between the Marshall stability,the residual Marshal stability,dynamic stability and the cement content,and then confirm the certain optimum cement content.更多还原
