摘要
分析砼在养护龄期内的收缩和膨胀理论，找出砼材料在施工龄期开裂的收缩机理，根据温度应力不超过水泥混凝土早龄期强度的原理，提出水泥混凝土路面的防裂新技术和锯缝时间的研究。
This article analyses the theoretical principle of the cement concrete shrinkage and expansion during the curing period. The authers try to find the reason of the concrete shrinkage cracks during construction period and the concrete frictional force under the moving loading. The paper presents a new technology of preventing cracks on cement concrete road surface and concrete sawed joint timing.
