PERFORMANCE SPECIFICATIONS FOR CONCRETE PAVEMENTS

The paper discusses the question of what characteristics of the portland cement concrete portion of a pavement will provide a 30 to 40 year durability under a certain E18 use when cast on a sound, engineered subgrade and base and that has properly installed joints. It is pointed out that the answer must be in the form of a detailed, technical description of the concrete composite. The description should include objectives for the paste, including entrained air, spacing factor, and the amount of trapped air; aggregate size and qualities including geological types with shape and texture limitations and particle distribution; in-place strength (after at least 90 days) in both flexural and compressible terms; relative density; permeability; and surface conditions. The need for research into the nature of the mixture is indicated. The performance contract, and two alternative contract arrangements are described. The need for defining the difference between good and poorly performing pavements is emphasized.
