PURPOSE: A repair and reinforcement method for an upper concrete structure of a bridge and an overpass using a reinforced composite member is provided to repair and to reinforce the damaged part of an overpass and a bridge rapidly and to heighten durability by preventing the leakage of a base and the permeation of chlorine to an upper structure of an overpass. CONSTITUTION: In an upper structure(1) formed by forming a resin mortar lining and a surface silica layer(3) on a concrete floor layer(8) fixed with a reinforcing bar(9), and placing a dense concrete surface layer on the upper plate formed by asphalt concrete(2) or the concrete floor layer(8) fixed with a reinforcing bar(9), the repair and reinforcement method for an upper concrete structure of a bridge and an overpass using a reinforced composite member is completed by inserting a composite board(4) between a concrete floor layer(8) and a dense concrete surface layer, placing a resin mortar lining layer on the concrete floor layer(8), or inserting a composite panel(4) attached with many C-shaped steels between upper asphalt-concrete surfaced layers(2). |
