Concrete Bridge Deck Crack Sealing

Bridge decks are prone to various types of cracking due to a combination of factors, including traffic loads, temperature variations, moisture, and chemical exposure. This report tackles the critical issue of bridge deck cracking by systematically dissecting the problem, exploring various crack types, and emphasizing the crucial inspection and categorization of cracks for effective remediation planning. The report focuses on the selection of appropriate sealants, considering regional conditions. It delves into remediation treatments, offering a spectrum of options based on National Bridge Inventory ratings, deck conditions, and crack characteristics. Additionally, the report classifies sealant products and introduces a cost-analysis framework, promoting well-rounded decision-making that balances short-term project costs with ongoing maintenance expenses. Serving as a valuable resource, the report equips decision-makers with knowledge and tools to optimize resource allocation, enhance bridge deck integrity, and improve maintenance practices.
