Keywords:RC slab, Replacement RC slab, Concrete base layer, Fatigue resistance, High durability adhesive

Fifty years have passed since the construction of the road bridge RC slab built during the period of high economic growth, and aging is progressing. However, it is designed with 245kN (25tf) after revision of the road bridge specification book and the commentary. For this reason, development of replacement floor version is urgently needed from re-deterioration of reinforced RC slab and B live load correspondence specified in the present specification. Therefore, in this research, we propose a concrete pavement technology applied with adhesive using replacement RC slabs with gaps, carry out wheel load running fatigue experiments, and verify the pavement effect and fatigue resistance.
