The research described herein was supported by the Strategic Highway Research Program (SHRP). SHRP is a unit of the National Research Council that was authorized by section 128 of the Surface Transportation and Uniform Relocation Assistance Act of 1987.

In a project as extensive and demanding as the SHRP A-005 project, the utmost efforts were called for and received from the project staff. Of particular note are the contributions of W. W. Crockford, Ming-Lou Liu, T. Freeman, C. K. Estakhri, Fuming Wang, C. H. Michalak, J. N. Galey, N. Stubbs, O. J. Pendleton, M. Chau, C. E. Schlieker, S. Phillips, and S. Cain with the Texas Transportation Institute (TTI) team. TTI secretarial services were provided by B. Cullen, C. Bryan, G. Fattorini, and S. Pierce. Noteworthy contributors from the Pennsylvania Transportation Institute team were S. Arnold, M. G. Sharma, W. Butlar, T. Farwana, N. Kim, K. Knechtel, W. Lauritzen, S. Reddy, P. Romero, N. Tabatabaee, and V. Tandon. SHRP technical staff who provided valuable assistance were H. Von Quintus and R. Leahy.

The objectives of SHRP's asphalt research were: to extend the life or reduce the life cycle costs of asphalt pavements; to reduce maintenance costs; and to minimize the number of premature failures. An important result of this research effort is the development of performance-based specifications for asphalt binders and mixtures to control three distress modes: rutting, fatigue cracking and thermal cracking. The SHRP A-005 project developed detailed pavement performance models to support these binder and mixture specifications and performance-based mixture designs. This report documents the findings of this extensive research effort and provides supporting data for the performance-based specifications and mixture design procedure called SUPERPAVE TM. SHRP Contracts A-002A (Binder Characterization and Evaluation) and A-003A (Performance-Related Testing and Measuring of Asphalt-Aggregate Interactions and Mixtures) accomplished three goals: 1) to identify relationships between asphalt binder properties and field performance; 2) to develop models for the estimation of pavement distress based the physicochemical properties of...
