COMPARISON OF SUPERPAVE WITH CONVENTIONAL PAVEMENT DESIGN

This paper contains an evaluation of Superpave Mix Analysis performance modeling for three pavement projects. Test results of the Superpave Shear Tester (SST) and the Indirect Tensile Device (IDT) are presented, along with calculated material properties and performance projections for each section. Pavement performance is estimated in terms of fatigue cracking and permanent deformation. The asphalt concrete overlay constructed at each site was designed using the Superpave Mix Design procedure with materials selected based on the aggregate and binder criteria included in the Superpave system for the traffic and climate of the location. Material properties were compared to the results determined using the Asphalt Institute's DAMA analysis program and the AASHTO design equation. Although these determinations are based on varying assumptions, behavior and distress modeling, material characteristics, and design parameters, there was agreement in some cases. Specific inconsistencies are discussed.
