Abstract
There have been reported fatigue damages of orthotropic steel bridge decks. As countermeasure of improving fatigue durability of existing orthotropic steel decks covered with asphalt bitumen, steel fiber reinforced concrete (SFRC) pavement is expected from the viewpoint that the deck plate is stiffened by the composite action of the concrete and the distribution of wheel loads is reduced by stiffness of it.
Static loading tests using 200kN dump truck were conducted on the orthotropic steel deck of Ohira viaduct. This paper reports the results of strains measurement before and after the construction of SFRC pavement that shows the great reduction effects of the local strains of steel decks.
