水泥混凝土路面是目前公路建设中广泛采用的高等级路面。然而,由于设计、施工、养护等诸多环节的不妥善,致使道路路面产生裂缝,有些裂缝甚至还很严重,从而成为影响水泥混凝土路面发展的一个关键性技术问题。本文总结了工程实践中的经验,就水泥混凝土路面裂缝产生的原因及如何消除外界因素的不良影响,以避免水泥混凝土路面裂缝的产生进行了一些探讨。
Cement concrete pavement is widely used in highway construction nowadays. However, due to improper design, construction, maintenance and many other links, the road pavement cracks and some cracks are even serious, thus becoming a key technical issue affecting the development of cement concrete pavement. This article summarizes the experience in engineering practice, and discusses the causes of cracks in cement concrete pavement and how to eliminate the adverse effects of external factors in order to avoid the cracks in cement concrete pavement.
