| 摘要 | The reinforcing method of the invention comprises the steps of removing asphalt from a concrete slab 2 of a road bridge, placing a reinforcing fiber sheet 20 onto the upper surface of the slab, preparing a fiber-reinforced composite material by impregnation with a resin 13 and causing the resin to set, coating an adhesive 22 onto a reinforcing material 21 comprising the foregoing composite material, sprinkling sand 23 thereover to form irregularities of sand 23 on the upper surface of the reinforcing material 21, hardening the adhesive 22, then coating a solvent-based asphalt primer 24 onto the sand 23, and placing asphalt 7 again, thereby completing the reinforcing operation. | ||||||
