在水泥混凝土路面施工中 ,采用压板法和切割法设置横向缩缝 ,常出现断板、板角破坏和啃边现象。对缩缝板材料的更新改造及施工工艺的选定 ,可较好地解决上述问题 ,从而提高了水泥混凝土路面的质量 ,降低了施工和养护成本 ,促进了水泥混凝土路面在高等级公路上更加广泛地应用和发展 In the construction of cement concrete pavement, the use of pressure plate method and cutting method to set the horizontal shrinkage, often appear broken plate, plate angle damage and eating edge phenomenon. The contractor plate material renovation and construction process selection, can better solve the above problems, thereby improving the quality of cement concrete pavement, reducing the cost of construction and maintenance, and promote the cement concrete pavement even more in high-grade highways Widely used and developed
