Project Name:	Optimal Binder Selection for High-Level Reclaimed Asphalt Pavement Mixes
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 Findings:	Data not yet available
Project Description:	Conduct binder and mix testing to evaluate blending of Reclaimed Asphalt Pavement (RAP) and virgin binder.
Laboratories:	Binder Laboratory Bituminous Mixtures Laboratory Chemistry Laboratory
Start Date:	October 1, 2009
End Date:	December 30, 2011
Funding Amount:	$0.00
FHWA Program Name:	Innovative Pavement Research and Deployment
Goals:	The key project objective is to better understand blending of Reclaimed Asphalt Pavement (RAP)/virgin asphalt binders. The current state of the practice is based on the assumption that complete blending occurs between the RAP and virgin binder. The hypothesis of this study is that complete blending does not occur; however, complete blending may not be necessary for proper performance in asphalt mixtures.
