Performance of Concrete Bridge Deck Surface Treatments
… surface treatments available for use on concrete bridge decks and to determine which materials are most capable of providing long-term protection from contamination by chloride ions. The products addressed in this report primarily include urethanes, silicon-based sealers, and epoxies. An extensive …

Evaluations of concrete overlays for bridge deck applications
Protective concrete deck overlays have been successfully used by WVDOH in a number of old and new concrete bridge decks to extend their service life, but in several cases delamination and failures have been observed. A comprehensive study has been recently defined to investigate overlays …

Effect of Lateral Stiffness on Bridge Deck Performance
The use of the empirical deck design method has increased its acceptance due to the economic advantages that it presents when compared to its counterpart, the traditional method. This can be attributed to the fact that the empirical method provides an appropriate design where the deck withstands …
