Project ID:	FHWA-PROJ-07-0015
Project Name:	Completion Of 67-80 Accelerated Pavement Testing Facility Mixture Fatigue And Rutting Characterization
Status:	Completed
Contact:	Last Name: Gibson First Name: Nelson H Telephone: 202-493-3073 E-mail: nelson.gibson@dot.gov
Organization:	Federal Highway Administration - Turner-Fairbank Highway Research Center (TFHRC)
Office:	Office of Infrastructure Research and Development
Team:	Pavement Materials Team
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.
Laboratories:	Bituminous Mixtures Laboratory
Start Date:	August 1, 2007
End Date:	December 31, 2008
Funding Amount:	$0.00
FHWA Program Name:	Innovative Pavement Research and Deployment
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 Type:	Onsite

Fieldtest:	Data not yet available
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). Audiences: Researchers, State highway agencies Secondary Audiences:

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.
