Experimental study on the Development of Thin-layer Pavement Method using Hybrid Epoxy for Concrete Bridge Deck Crack Repair

콘크리트 교면포장 균열 보수를 위한 하이브리드 에폭시 박층포장 보수공법 개발에 관한 실험적

A method for repairing cracks using low-viscosity resins has been proposed as a construction method that can quickly repair roads from deterioration. However, when the viscosity of the epoxy resin is high, there is a limit in that it is difficult for the material to penetrate into microcracks and cracks in the concrete top plate. In this study, an epoxy thin-layer pavement repair method was developed using low-viscosity PMMA (Poly methyl methacrylate) to repair microcracks on the pavement surface and pavement layer and reinforce the pavement surface. Materials necessary for the thin-layer packaging method were developed, and performance was evaluated to meet the epoxy binder quality standards. As a result, all materials met the required performance.
