Title: THIN POLYMER CONCRETE OVERLAYS FOR BRIDGE DECK PROTECTION
Abstract: The installation of thin polymer concrete (PC) overlays on portland cement concrete bridge decks during the past 3 years has demonstrated that overlays of low permeability and high skid resistance can be successfully installed with a minimum of disruption to traffic. The initial condition of the overlays has been excellent from the standpoint of permeability, skid resistance, and bond, although some overlays have been better than others. In this paper the potential of thin PC overlays for extending the service life of bridge decks is discussed. The bond achieved between the overlay and the deck concrete, the protection provided by the overlay, and the tensile properties of the resins and how they affect the performance of the overlays are described. The cost of a PC overlay is compared with that of a more conventional, latex-modified concrete overlay, and insight is provided about when to specify a PC overlay based on considerations of service life, traffic volume, discount rate, and the value of driving time.
