PMSS Project Details

Project ID:	FHWA-PROJ-12-0066
Project Name:	Asphalt Component and Additive Compatibility
Status:	Active
Contact:	Last Name: Youtcheff First Name: Jack Telephone: 202-493-3090 E-mail: jack.youtcheff@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:	Various asphalts will be characterized (elemental analysis, spectroscopic characterization, solvent dissolution) and a model will be developed for predicting the phase behavior of mixes. The second phase of work will separate large quantities of reclaimed asphalt pavement (RAP) and reclaimed asphalt shingles (RAS) binders using ionic liquids.
Laboratories:	Chemistry Laboratory Binder Laboratory Bituminous Mixtures Laboratory
Start Date:	October 1, 2012
End Date:	December 31, 2013
Funding Amount:	$0.00
FHWA Program Name:	Innovative Pavement Research and Deployment
Goals:	Predict phase behavior (compatibility) of asphalts obtained from various sources, including materials extracted from reclaimed asphalt pavement and recycled asphalt shingles.
Project Type:	Onsite and Offsite
Background Information:	Previous work resulted in development of a guide for determining solubility parameters.
Test Methodology:	Spectroscopic characterization of asphalts, asphalt additives, and asphalt components using nuclear magnetic resonance (NMR) and Fourier Transform Infrared (FTIR).
Other Information:	Data not yet available
Partners:	Data not yet available

Expected Benefits:	Guide for evaluating the propensity for asphalt and asphalt additive (modifier, reclaimed asphalt pavements, reclaimed asphalt shingles, etc.) to blend. This will aid in understanding "black rock" issues using recycled products.
Deliverables:	Name: Asphalt Compatibility Model Product Type(s): Research report Description: Model for predicting miscibility of asphalt and asphalt components. Audiences: Federal Turner-Fairbank Highway Research Center staff, Researchers Secondary Audiences:
