Fibre waviness in pultruded bridge deck profiles: Geometric characterisation and consequences on ultimate behaviour

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...

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 ...

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...

Testing and Evaluation of Components for a Composite Bridge Deck

Planning and Optimizing Bridge Deck Construction Using Computer Simulation

This paper presents a framework (named Bridge_Sim) that aids contractors in planning bridge deck construction using computer simulation. The proposed framework estimates the time and cost required for construction of bridges' decks. Seven construction methods are included in the proposed framework. These are: cast-in-place on falsework, steel bridge construction, cantilever carriage, pre-cast b...
