EXAMPLES OF REPAIR AND RETROFIT WORK ON ROAD BRIDGE STRUCTURES
Japan has a network of some 1,110,000 km public roads covering all the territory including remote islands, and administrates as many as 580,000 bridges ranging a 2m-long culvert to a long suspension bridge. These bridges subjected to severe natural conditions, heavy traffic loads and sometimes strong motion of earthquakes are liable to sustain injuries and harm in years after their construction. Repairing and retrofitting damaged bridges against further harm is a work of great importance from the socio-economical point of view amind a low-growth economic circumstance of the country. Here, the author introduce general concepts of repair and retrofit works on road bridge substructures with an emphasis on concrete structures, and then show some examples of the works. (Author)
