Full-Scale Accelerated Performance Testing for Superpave and Structural Validation

The purpose of the research is to select, build and study 12 lanes of pavement, with testing conducted using the Federal Highway Administration (FHWA) Accelerated Loading Facility (ALF) machines. The experiment is focused on developing field performance data on hot-mix asphalt mixtures with modified binders. This is an important step in a larger program to refine the Superpave binder specification for the modified materials. Secondary goals include: 1) early trial of the proposed 2002 Pavement Design Guide; 2) evaluation of crumb-rubber modified asphalt pavements; 3) correlation of field performance with results of laboratory tests (e.g., the Superpave Simple Performance Test).
