摘　　要：为保证水泥混凝土路面行车安全,文中对新老混凝土界面薄弱原因进行了分析,采用弯拉黏结试验方法进行界面黏结性能检验,试验结果表明:各种附加应力的作用导致水泥混凝土路面修补材料与原路面界面发生破坏;矿渣基这一新型水泥混凝土路面修补材料配以掺加膨胀剂的水泥浆作为界面黏结剂,能够提高界面黏结性能。In order to ensure the traffic safety of cement concrete pavement,in this paper,the reason of new and old concrete interface weakness is analyzed,and the flexural bonding experiment method is used to test performance of the interface bonding.From the test results,the effect of various additional stresses leads to the destruction of the interface between the repairing material of cement concrete pavement and the original pavement.The slag base is verified as a new type of repair material,which matched with cement paste contains expansion agent as an interface boning agent,and the interface bonding performance can be improved very well.

关 键 词：水泥混凝土路面 界面黏结性能 弯拉黏结试验 膨胀剂
