Bridge lining renewal method, involves roughening concrete layer by high-pressure water jet or by fine milling, applying mat reinforcement on roughened concrete layer, and applying new pavement on bridge

摘要

The method involves removing an existing covering and/or an existing lining applied on a concrete layer (4). The concrete layer is roughened by a high-pressure water jet or by fine milling, and a mat reinforcement (3) is applied on the roughened concrete layer, where an adhesive strength of about 2 Newton per square mm is produced between the mat reinforcement and the mat reinforcement by roughening the concrete layer. A new pavement (2) is applied on the bridge, where the mat reinforcement is applied on the roughened concrete layer without a primer.
