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.
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).
Output: Surrogate test to full-scale Accelerated Pavement Testing Facility loading (performance testing for superpave and structural validation). [Source: FHWA, PMSS Database (2013)]
