—vŽ| Damage and repair of the deck of many aging bridges are major social problems in our country. In this research, in order to reproduce the deterioration process of bridge deck, preliminary loading was carried out by a testing machine equipped with a rubber tire. After that, the damaged bridge deck was reinforced by the carbon fiber, and a fatigue loading test by a crank type testing machine up to destruction was done. Based on a series of experimental results, it was confirmed that the concrete slab was extended by carbon fiber reinforcement in only axis direction of the bridge, and fatigue durability was improved.@
