Material Properties of the 2003 NCAT Test Track Structural Study

The objectives of this report included: (1) document the material properties of the component pavement layers, to serve as a reference, for the 2003 Structural Study at the National Center for Asphalt Technology (NCAT) Test Track; (2) establish relationships between relevant parameters (e.g., temperature) and mechanistic material properties [e.g, hot mix asphalt (HMA) stiffness]; (3) characterize differences between laboratory and in situ material properties; and (4) determine the effects of material types on mechanistic material properties. This report describes the component pavement layers in terms of material composition and mechanistic material properties. Laboratory triaxial resilient and dynamic modulus tests were conducted and are described herein. Further, extensive falling weight deflectometer (FWD) tests were conducted on the pavement sections throughout the two-year study. The data from both laboratory and field were evaluated statistically and models were developed to characterize relationships between relevant pavement parameters and mechanistic material properties. Finally, comparisons were made between laboratory and field properties.
