摘要
随着交通事业的蓬勃发展,高速公路桥梁桥面铺装层频繁出现裂缝、松散、坑槽等病害,维修周期也越来越短。文章针对20世纪90年代修建的某高速公路中小跨径连续刚构桥,结合桥面铺装病害现状,分析病害原因,提出桥面铺装改造设计方案和施工工艺,为桥面铺装的凿除重做施工提供了有益指导,取得了良好的应用效果。
With the vigorous development of the transportation industry,cracks,looseness,potholes and other diseases occur frequently in the deck pavement of highway bridges,and the maintenance cycle is getting shorter and shorter.Aiming at the continuous rigid frame bridge with small and medium span of a highway built in the 1990s,combining with the disease status of bridge deck pavement,this paper analyzes the causes of disease,and puts forward the design scheme and construction technology for bridge deck pavement reconstruction,which provides useful guidance for the construction of bridge deck pavement chiseling and reworking,and has achieved good application results.
