| Roadmap/Focus area(s): | Infrastructure Research and Technology Strategic Plan and Roadmap | |
| 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). | |
| Product Type: | Research report | |
| Expected Benefits: | The payoffs are more accountable binder purchase specifications leading to more efficient construction; expanding the set of materials characterized in axial push-pull to explore more practical variations on the theory and protocols which advance the test towards implementation; and partnering with the Federal Highway Administration Office of Infrastructure to demonstrate mixture characterization tools and binder specifications on the mobile asphalt trailer. | |
| Deliverables: | Name: Performance Testing for Superpave and Structural Validation Product Type(s): Research report Description: Final Report from TPF-5(019) and 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. | |
