SPR-4320: Implementation of Epoxy Injection of Concrete Overlaid Bridge Decks
| 项目名称： | SPR-4320: Implementation of Epoxy Injection of Concrete Overlaid Bridge Decks |
| 摘要： | Concrete overlay has proven to be effective maintenance treatment as it prevents de-icing chemicals and water penetration into the original deck surface. Typically, over time, debonding develops at the boundary between the original deck and overlay which creates void. Displacing water and filling these cracks with epoxy helps eliminate freeze and thaw and reduces spalling requiring emergency patching, and thereby extending the bridge deck life span. This process is envisaged as an end of bridge deck life treatment. The ultimate goal is to forgo another costly deck rehabilitation project and save that money for a deck replacement, or superstructure replacement in the near future. |
