Abstract
In this study, the authors newly proposed patch repair materials and repair method of RC slab with top surface damage, and wheel running load fatigue test were carried out on test specimens given primary, secondly and tertiary repair to evaluate the fatigue resistance of repair-cycle. The result showed that, the repair method using Ultra rapid fiber cement mortar of two types and high durability type epoxy resin adhesion proposed this study showed high resistance to the crack and Peeling in a repair interface and advancement of fatigue resistance proved than the traditional repair method using Ultra rapid cement mortar. Repair-cycle was possible to two cycles, but in three cycles the authors proposed taking the measure for improving a load carrying capacity.
