PMSS Project Details

Project ID:	FHWA-PROJ-12-0041
Project Name:	Asphalt Mix Compaction Modeling
Status:	Terminated
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 research will utilize flexible wall, triaxial consolidation of hot-mix asphalt (HMA) job mix formulas as a more fundamental measure of compaction rather than Superpave gyratory compaction to rank the compactability. The ranking will be paired with an on-the-market Aggregate Imaging System, which now has an established American Association of State Highway and Transportation Officials provisional protocol and basic practical volumetric measures.
Laboratories:	Binder Laboratory Bituminous Mixtures Laboratory
Start Date:	June 4, 2012
End Date:	June 4, 2015
Funding Amount:	$0.00
FHWA Program Name:	Turner-Fairbank Highway Research Center
Goals:	Address the gaps in the calibration inputs for previously completed "Modeling of Hot-Mix Asphalt Compaction: A Thermodynamics-Based Compressible Viscoelastic Model."
Project Type:	Onsite
Background Information:	See "Modeling of Hot-Mix Asphalt Compaction: A Thermodynamics-Based Compressible Viscoelastic Model Publication No. FHWA-HRT-10-065."
Test Methodology:	Image processing, Ancillary Information Management System (AIMS) device, Superpave gyratory compactor (SGC), multivariable correlation
Other Information:	Data not yet available

Fieldtest:	Data not yet available
Expected Benefits:	Ability to design mixtures with desirable compaction characteristics and improved performance.
Deliverables:	Name: Predictive methodology to determine aggregate characteristics’ influence on general compactability and Superpave gyratory compactor (SGC) compaction curves that serve to enhance calibration procedure for existing compaction model constitutive inputs. Product Type(s): Research report, Software, Draft standard, specifications, or guidelines Description: By simply measuring the Ancillary Information Management System (AIMS) characteristics and knowing the job mix formula volumetrics, practitioners will be able to rapidly predict behavior of mixtures in laboratory compaction and expected field compaction.
