水泥混凝土路面具有承载能力大、稳定性好、使用寿命长、日常养护费用少等优点,是高等级、重交通公路路面的重要类型之一,并具有良好的发展前景,但从已建成通车的水泥混凝土路面使用情况看,有相当部分发生了破坏:如开裂、唧泥、错台、沉陷、拱起、横向断板等病害。根据笔者对已施工过的几条混凝土路面的经验,从路基施工、路面施工及路表排水处理等方面,较细致地分析了造成水泥混凝土路面破坏的一些往往被忽视的环节。
Cement concrete pavement has the advantages of large carrying capacity, good stability, long service life and low daily maintenance costs. It is one of the important types of high-grade and heavy traffic pavement and has good development prospects. However, The use of cement concrete pavement, there is a considerable part of the damage occurred: such as cracking, pitting mud, the wrong Taiwan, subsidence, arch, cross-plate and other diseases. According to the author’s experience on several concrete pavements that have been constructed, some frequently overlooked aspects of concrete pavement damage have been analyzed in detail from the aspects of roadbed construction, pavement construction and road surface drainage.
