摘　　要：水泥混凝土路面在使用过程中,不可避免地会产生破损,而传统的修补材料受到造价和交通开放时间的制约,会导致病害进一步加剧。针对这一问题,提出矿渣基修补材料,在分析修补机理的基础上,通过正交试验从凝结时间、强度、干缩性3方面确定其配方,并与路面施工中常用的普通硅酸盐42.5级水泥进行砂浆性能对比,验证了这种新型修补材料具有一定的优越性和广泛推广应用价值。Cement concrete pavement inevitably led to the breakage in the process of application,the traditional repair material is restricted by the cost and traffic opening time,the disease will be aggravated.In response to this problem,slag based repair material was introduced.Based on the analysis of the repair mechanism,the formula was determined from the three aspects of setting time,strength,dry shrinkage through the orthogonal test,and comparative analysis of mortar performance with the ordinary silicate cement 42.5 which used commonly in pavement construction,and the new repairing material has certain superiority and broad application was verified.
