Bridge Deck Program (August 1992)
The purpose of this report is to provide an update on the status of the Washington State Department of Transportation (WSDOT) Bridge Deck Program. Included is information on types of materials, construction techniques, and policies used by WSDOT to rehabilitate bridge decks. A condition survey has been completed on all unprotected WSDOT concrete bridge decks. This data has allowed the department to improve its rehabilitation and protection program policies and strategies. Based on this data, 866 concrete bridges will probably not require protection during their life. These bridges are designated as a 'Do Nothing' group. Over the past eight years, WSDOT has applied and evaluated more than a dozen new bridge deck protection systems. These systems have included modified concretes, thin polymer concretes (thin PC), and polyester-styrene polymer concretes (PSPC). Providing a cost effective durable overlay and considering rapid construction needs where possible has been a primary objective of these new systems. Modified portland cement concrete overlays continue to be the department's preferred protective system based on in-service performance. Current special provisions allow a contractor to use either microsilica or latex modified concrete design mixes when a concrete overlay is specified.
