TRB’s Transportation Research Record, Journal of the Transportation Research Board, No. 2220 includes 11 papers that explore portland cement concrete exposed to automated deicing solutions; identification and tracking of highway bridge maintenance; health monitoring of prestressing tendons in posttensioned concrete bridges; bridge maintenance in New York City, New York; multicriteria bridge management at the network level; and estimating the timing of rehabilitation and replacement of bridge elements. This issue of the TRR also examines condition survey of older West Virginia bridge decks constructed with epoxy-coated reinforcing bars, effect of initial timing of scarification and overlay treatment on chloride concentrations in concrete bridge decks, effects of concrete mix on initiation of reinforcement, corrosion and chloride threshold level, light-emitting diode warning beacons for maintenance vehicles, and equipment replacement optimization.
