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...
متن کاملBridge 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 ...
متن کاملFatigue Response of Bridge Deck Link Slabs Designed with Ductile Engineered Cementitious Composite (ECC)
Link slabs designed for macroscopically crack free concrete bridge decks system were experimentally tested. The property requirements of the link slab material were considered. Special focus was placed on the fatigue and durability performance. Introduction of a ductile Engineered Cementitious Composite (ECC) material is proposed for its ability to control crack width and to exhibit high ductil...
متن کاملDesign Analysis of Single-span Advanced Composite Deck-and-stringer Bridge Systems
There is a concern with worldwide deterioration of highway bridges, particularly reinforced concrete. Due to the corrosive nature of steel re-bars used in concrete bridge decks, the service-life of these bridges is reduced. The advantages of advanced composite materials (ACM) over conventional materials motivate their use in highway bridges for rehabilitation and replacement of structures. Howe...
