Validation of Rehab Strategies to Extend the Service Life of Concrete Bridge Decks

The objectives of this research is to investigate the long-term deteriorating effect of vehicular wheel loading relative to that of environmental loading on Caltrans reinforced concrete bridge decks, as well as to look into the long-term effectiveness of Caltrans' preservation and rehabilitation strategies for concrete bridge decks. Caltrans currently employs high molecular weight methacrylate (HMWM)-based crack sealing and polyester overlay. This research will also explore the value of Portland cement concrete (PCC) and asphalt concrete (AC) overlays on bridge decks, and identify the appropriate treatment time and frequency for these strategies.
