水泥路面防裂断方法的探讨

Discussion on the Method to Prevent Concrete Pavement Cracking

针对当前农村公路水泥路建设过程中出现的断板现象,本文通过大量工程实践和裂断过程试验,根据温度应力不超过混凝土早龄期强度的原理,提出用板温控制确定锯缝时机的方法,对水泥路面防裂断方法进行了有益的探讨。

Based on the phenomenon of broken plates in the construction of rural cement road, this paper through a large number engineering practice and breaking process testing, according to the principle of the temperature stress not more than the concrete strength in early age, proposed the method to determine the sawing seam opportunity using the board temperature control, and discussed the method to prevent concrete pavement cracking.
