PMSS Project Details

Project ID:	FHWA-PROJ-09-0048
Project Name:	Asphalt Sustainability Issues: Evaluation of Long-Term Performance of Recycled Additives, Including Recycled Motor Oil, Reclaimed Asphalt Pavements, Reclaimed Asphalt Shingles, and Bioasphalts
Status:	Active

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):	Environmental Streamlining/Stewardship Infrastructure Research and Technology Strategic Plan and Roadmap
Project Findings:	The Solubility Calculator provides a good estimate of solubility parameters for binders and polymers; however, the values for most asphalt binders are nearly the same. The application will be much more useful when applied to asphalt components such as maltenes (and their subfractions) and asphaltenes.
Project Description:	The computer program for calculating solubility parameters is based on a) elemental composition and aromaticity and b) group (chemical functional groups) contributions. Solubility parameters for blended material are needed to generate phase behavior diagrams.
Laboratories:	Chemistry Laboratory
Start Date:	September 15, 2009
End Date:	December 31, 2012
Funding Amount:	$0.00
FHWA Program Name:	Innovative Pavement Research and Deployment
Goals:	The key project objectives are: 1. Develop a computer program for calculating solubility parameters of asphalts, asphalt components, and additives. 2. Use solubility parameters to predict phase behavior tendency of asphalt and asphalt-additive blends.
