Abstract:

Presented in this report is information concerning the characteristics of the concretes used to construct six experimental two-course bonded bridge decks in Virginia. The quality of the overlay concretes produced under standard specifications supplemented with special contract provisions is described. Recommendations are made concerning the attainment of desired cover depths over the topmost reinforcement and the attainment of adequate consolidation in the overlays. The several procedures that have been used to compare the condition of the two-course decks with that of conventional, single-lift control decks are discussed, and it is concluded that the two-course decks indicate a greater potential for satisfactory performance. Determinations of future performance will be based on comparisons of data from tests as visual surveys and soundings, chloride analyses, electrical potentials, sonic pulse velocities, and skid resistance of the decks.
