The wide ranging environmental conditions and raw materials of the northeastern United States have created conditions that accelerate the deterioration of highway bridges and structures. The saturated freeze-thaw cycling, alkali-silica reaction susceptible aggregates, annual thermal cycles, and heavy use of deicing salts have reduced the life of the average bridge superstructure to 28 years. The use of high performance concrete specifications is being used to increase the life of new bridges and highway structures and decrease the life-cycle costs of the bridge inventory in the northeastern United States. The specifications require an evaluation of the structures loadings and environments, classification of the exposure and risk level, performance based concrete mixtures and new quality control measures to place and cure long-life structural elements.
