EVALUATION OF BRIDGE DECK REPAIR AND PROTECTIVE SYSTEMS
This report describes efforts to control bridge deck deterioration in Colorado. A follow up testing program to determine the degree of continued effectiveness of waterproofing membranes has been underway since 1974. Results to date show that the most important factor is how well a membrane is placed. Several projects in Colorado have employed the use of Latex Modified Concrete as a surface wearing and protective course. Recent inspections of latex modified bridge decks indicate that some significant cracking is beginning to take place. Chlorides are entering these cracks and steel corrosion may be in progress at these points. Considerable time may be required, however, to determine if the corrosion progresses laterally and the true value of this design. /FHWA/
