Abstract:

PRESENTATION The Corrosion Problem in Pavements Nature of the Vitreous-Ceramic Coating Ease of Application to Reinforcement Steel Bond Strength and Corrosion-Resistance Field Demonstration Program Testing in Reinforced Concrete Pavement Summary of Current Status. FRAMING THE PROBLEM The predicted service life of continuously reinforced concrete pavement can be shortened if the rebar in the pavement corrodes prematurely and delaminates the pavement. Moisture and chlorides can move through the natural porosity of concrete and the cracks in the pavement Application of chlorides from natural sources and from deicing compounds can greatly speed up the corrosion process.
