  • Abstract:
    Preventative maintenance of our infrastructure elements is increasingly vital as the resources to repair and replace these elements become scarce. One form of preventative maintenance is to protect structures from damages inflicted from deicing and anti-icing practices. A low-cost preventative maintenance strategy is the use of protective coatings for bridge decks. Bridge deck concrete is often flawed by cracks. These cracks provide ingress for chloride ions to the reinforcement of the deck and structure. In order to prevent the further ingress of chloride ions, sealers and laminates are often considered practical methods of protection. This research project developed a protocol to evaluate concrete sealer and laminate effectiveness in protecting bridge deck concrete from chloride ion ingress. The protocol developed includes criteria for selecting products for evaluation, sample locations, sample depths, duration of study as well as the method of analysis of the chloride ions present in the concrete dust collected. The results demonstrate not only the relative effectiveness of the various sealers and laminates, but also the durability of each product as compared to control structures without a sealer or laminate applied. The durability and cost of the products can be used to develop the relative cost-effectiveness of each product. The cost-effectiveness values were utilized to develop the recommended policy for the use of bridge deck sealers and laminates for preventative maintenance.
