| Abstract: | For the problems of bridges＇ pavement which affect use,safeguard and maintenance of bridges,the common disease mechanisms of pavement of package prestressed concrete hollow plate bridges are analyzed,which include the longitudinal and transverse cracks along bridge,the polygonal cracks,the loose and exfoliation as well as the damage at expansion joint,and so on.The relating design and construction measures are suggested.The status of research and application of synthetic fiber reinforced concrete,composite fiber reinforced concrete,and steel fiber reinforced lightweight concrete,in bridge pavement,are summarized.Some research problems needed to be further studied are listed. |
