THIN-BONDED POLYMER CONCRETE OVERLAYS FOR EXPOSED CONCRETE BRIDGE DECK PROTECTION AND MAINTENANCE
Various polymer concretes have been used as overlay materials for bridge deck rehabilitation since the 1950s. The intent of these thin-bonded polymer concrete overlays is to provide a smooth-riding, durable, wear resistant surface as well as a protective covering against water and deicing salts. Project requirements, as well as product limitations, have changed considerably over the last forty years as improvements have continually been made to the process. Carefully prepared material specifications are necessary to assure an overlay that lasts. Overlays of this type have documented performance in the USA of up to 20 years in harsh environments. Recommendations are made to improve project specifications in the following areas: tensile elongation, abrasion resistance, water absorption, chloride ion permeability, and quality standards.
