The present invention provides a method for repairing and reinforcing an expansion joint equipment part using resin mortar, which is advantageous to prevent salt damage to road facilities not responsive to calcium chloride without an alkali aggregate reaction, secures perfect watertightness as a dense polymer assembly without an air gap, suppresses generation of impact, vibration absorption, and crack due to elasticity of an elastic resin so as to be advantageous to a structure that behaves such as a bridge or the like, fundamentally prevents freezing damage by realizing perfect watertightness, is resistant to ultraviolet rays, and has strong wear resistance to weathering, by applying resin mortar to an aged portion of an expansion joint equipment part. In order to achieve the above objective, the method for repairing and reinforcing an expansion joint equipment part using resin mortar according to the present invention comprises the steps of: cutting bridge pavement where expansion joint equipment is installed; fracturing reinforced concrete of the cut portion of the pavement; cleaning the fractured portion of reinforced concrete with high-pressure water; applying a strengthening agent to the fractured portion of reinforced concrete cleaned with the high-pressure water; applying resin mortar to a surface of the strengthening agent; and applying a primer coating agent to a surface of the resin mortar. |
