摘　　要：阐述了填缝材料的选用原则和性能要求,对我国中部地区水泥路面的几个路段的切割缝的伸缩缝进行了实地测量,并考察了填缝材料的使用情况,发现气候差异、材料性能及是否及时对切割缝进行处理等是导致水泥混凝土路面产生各种病害的原因,提出填缝材料必须具有良好的粘结性、优良的耐候性和一定的弹性恢复能力和抗嵌入能力。The selection principia and the performance demand were expatiated in the paper. The change of cement pavement joint in central China was measured, and the use instance of joint sealant was examined. The result of the investigation shows that joint sealant must own excellent bonding property, weather resistance, elastic recovery and embedding resistance in a certain extent.
