Construction Technology and Quality Control of Expressway Bridge New Concrete Deck Pavement

The current situation of bridge deck diseases in China＇s main expressway bridge shows that it becomes an urgent task to adopt new type of concrete materials and construction technology to improve the quality of the bridge deck pavement engineering. This paper introduces the construction technology and quality control in both the high-performance salt frost resistance of concrete bridge deck pavement and steel fiber reinforced concrete bridge deck pavement. The paper proposes that the design require- ments and related specifications should be strictly complied with during bridge deck pavement construc- tion. What＇s more, the innovation ability should be developed, the emerging technology and construction technology should be reasonably used on the premise of guarantee the quality of construction.
