摘　　要：文中利用四种不同集料进行高摩擦道路表面处治(HFST),测试了不同集料组成的HFST微波加热效果,利用摩擦摆值测定评价了其相应的抗滑性能.结果表明:铁矿石和钢渣集料的升温速率分别为1.580 3和1.276 3,而玄武岩和煅烧铝矾土集料的升温速率分别为0.886 1和1.114 3,因此,钢渣和磁铁矿可作为吸波材料代替传统铝矾土集料用于HFST的材料组成设计.HFST试件的微波加热性能与钢渣和磁铁矿对铝矾土集料的取代率成正比.而随着钢渣和磁铁矿替代率的增加,二元体系试件的摩擦摆值均呈现降低趋势,磁铁矿-煅烧铝矾土体系表现出较为稳定的摩擦表现,钢渣-煅烧铝矾土体系的摩擦表现波动较大.Four kinds of different aggregates were used for high friction road surface treatment(HFST),and the microwave heating effect of HFST with different aggregate composition was tested.Then the corresponding anti-sliding performance was evaluated by measuring the friction pendulum value.The results show that the heating rates of iron ore and steel slag aggregate are 1.5803 and 1.2763,respectively,while the heating rates of basalt and calcined bauxite aggregate are 0.8861 and 1.1143,respectively.Therefore,steel slag and magnetite can be used as absorbing materials to replace traditional bauxite aggregate in the material composition design of HFST.The microwave heating performance of HFST specimen is directly proportional to the replacement rate of bauxite aggregate by steel slag and magnetite.With the increase of the substitution rate of steel slag and magnetite,the friction pendulum values of binary system specimens all showed a decreasing trend,and the friction performance of magnetite-calcined bauxite system showed a relatively stable performance,while the friction performance of steel slag-calcined bauxite system fluctuated greatly.
