Project Details

Project Description: 

The purpose of this activity is to capitalize on recent laboratory fatigue and rutting characterization studied in conjunction with Accelerated Pavement Testing Facility Performance. Flow number and axial push-pull characterization now have a measure of credibility as a surrogate test to full-scale Accelerated Pavement Testing Facility loading.

Goals

To provide a more robust and discriminating rutting and fatigue laboratory characterization of mixtures tested in full scale in TPF-5(0127) & SPR-2(174).

Project Findings: 

The confined tests in the Asphalt Mixture Performance Tester (AMPT) had an improved rank order association (like a correlation) to Accelerated Load Facility (ALF) rutting compared to unconfined tests. Simplified viscoelastic continuum damage tests have time savings advantages over classical beam fatigue, rank well with full-scale fatigue cracking, and have the potential to be run in the Asphalt Mixture Performance Tester (AMPT), which is now possible.
