浅析水泥混凝土路面的裂缝

On cracks on cement concrete pavement

通过对水泥混凝土路面裂缝的概述,分析了路面开裂的机理,提出了防止水泥混凝土路面开裂的技术措施,根据温度应力不超过混凝土早龄期强度的原理,提出用板温控制锯缝时机的方法,以达到控制路面开裂的目的。

According to the survey of the cracks on cement concrete pavement, the paper analyzes the mechanism of cracks on pavement, points out the technological measures for preventing the cement concrete pavement from cracks, and illustrates the method which controls the saw kerr time by the strip temperature, according to the mechanism that the temperature stress is no higher than the intensity of the concrete at early age, so as to control the cracks on the pavement.
