TRC1903 - Investigating Concrete Deck Cracking in Continuous Steel Bridges

Concrete bridge deck cracking creates serious serviceability issues during a bridge design's life, and can compromise a bridge's structural strength. This project aims to identify the primary causes of deck cracking, as well as determining the stresses in the due to concrete slab movement during shrinkage. After determining the cause for bridge deck cracking, long-term corrective measures will be recommended to prevent future cases of bridge deck cracking. The current objective in this project is to review documents about bridge deck cracking in Arkansas and look for correlations between projects. After reviewing the procedures contractors go through when pouring a bridge deck, examine previously constructed bridges and determine the best mapping of strain gauges for examining the stresses inside of a freshly poured concrete bridge deck.
