我国的公路事业进入了以建设高速公路、一级公路等高等级公路为主的新时代。早期修建的一些水泥混凝土公路,在没有达到设计年限的情况下,致使道路路面产生裂缝,有些裂缝甚至还很严重,并开始进行大修。不仅对社会、交通造成了较大的影响,也在经济上造成了很大的损失。本文结合混凝土路面的施工工艺,深入分析其路面裂缝的特征及成因,以避免水泥混凝土路面裂缝的产生进行了一些探讨。 Our country’s highway career has entered a new era featuring high-grade highways such as expressways and primary roads. Some of the cement concrete roads built earlier did not reach the design deadline, resulting in cracks in the road pavement. Some of the cracks were even serious and the overhaul began. Not only the social and transportation have a greater impact, but also caused great economic losses. In this paper, the construction process of concrete pavement, in-depth analysis of the characteristics and causes of pavement cracks in order to avoid the cracks on the cement concrete pavement some of the discussions.
