Project description

Bridge decks are the weakest link among the various bridge components, lasting approximately 30 years. According to the American Association of State Highway and Transportation Officials (AASHTO) Load and Resistance Factor Design (LRFD) specifications, a bridge deck should be expected to last for 75 years. Bridge decks are exposed to excessive traffic and chloride elements. The chloride elements can seep through cracks within the bridge decks, causing corrosion in the steel. High durability concrete has been used to improve the serviceability of structures.
