目前,随着高等级公路的高速发展,桥梁的数量增多,许多桥建成通车之后不久就出现了问题,给车辆的运行和桥梁的维修带来诸多不便。在公路桥梁中,桥面行车道铺装一般采用水泥混凝土,高等级公路的大中桥桥面多采用水泥混凝土和沥青混凝土双结构层铺装,由于桥面铺装在我国尚缺乏较成功的经验,再加上施工工艺上的不足,使得桥面铺装在施工过程中常出现一些病害问题。现就水泥混凝土桥面铺装和沥青混凝土桥面铺装的问题进行分析,并结合自身的施工经验探讨一些行之有效的预防改进措施。
At present, with the rapid development of high-grade highways, the number of bridges has increased, problems have arisen shortly after the completion of many bridges and have brought inconvenience to vehicle operation and bridge maintenance. In highway bridges, the deck pavement generally use cement concrete pavement, high-grade highway bridge deck and more use of cement and asphalt concrete double pavement, the bridge deck pavement in our country still lack more successful Experience, coupled with the lack of construction technology, making the bridge deck in the construction process often appear some disease problems. Now on the cement concrete pavement and asphalt concrete pavement problems are analyzed, combined with their own experience in construction to explore some effective preventive measures.
