Abstract:
Latex modified overlays have been in service for over 20 years. This report summarizes the significant events during the development of this system and highlights data that have recently been generated by State Highway Departments and the FHWA in their continuing studies of field performance. Fifteen reports, covering 184 bridge decks, aged two months to 13 years, are reviewed. Specific comments regarding test methods, such as chloride pen-etration and half-cell potential, to measure performance, are included. Life expectancy, based on the testing done to date, as well as the actual life in the field, is projected to be a minimum of 15-20 years.
