Detection of Bridge Deck

Delamination is probably the most serious form of deterioration I which is commonly found in britlge decks. It ultimately results in large scale spalling necessitating costly repairs. This type of failure is believed to be caused chiefly from salt induced corrosion of the reinforcing steel. An instrument designed to detect delamination, and tests conducted to val:iAate its perf'ormance, are .br...

Physical Modeling on Hydraulic Performance of Rectangular Bridge Deck Drains

This paper presents results from an extensive experimental study on hydraulic performance of new rectangular bridge deck drains developed by the Texas Department of Transportation (TxDOT) Bridge Division. It fits between the deck reinforcement with the top of the drain flush with the bridge surface and does not interfere with the structural connection of the bridge rail to the deck. Experiments...

Bridge Deck Deicing

Concrete bridge decks are prone to ice accumulation. The use of road salts and chemicals for deicing is cost effective but causes damage to concrete and corrosion of reinforcing steel in concrete bridge decks. This problem is a major concern to transportation officials and public works due to rapid degradation of existing concrete pavements and bridge decks. The use of insulation materials for ...

Investigation of a Suitable Shear Friction Interface between UHPC and Normal Strength Concrete for Bridge Deck Applications
