Project ID:	FHWA-PROJ-07-0033
Project Name:	Modeling Hot-Mix Asphalt Compaction
Status:	Completed
Contact:	Last Name: Weaver First Name: Eric J Telephone: 202-493-3153 E-mail: eric.weaver@dot.gov
Organization:	Federal Highway Administration - Turner-Fairbank Highway Research Center (TFHRC)
Office:	Office of Infrastructure Research and Development
Team:	Pavement Design and Construction Team
Roadmap/Focus area(s):	Infrastructure Research and Technology Strategic Plan and Roadmap
Project Description:	Develop a fundamental model for the compaction of hot-mix asphalt. The project has been initiated and it involves identifying potential models, relating model parameters to the lab and the field, selecting a suitable model, sensitivity analysis, verification, and finally delivery. This will also require coordination with efforts at the development of new roller equipment with intelligent compaction capabilities.
Laboratories:	Not Applicable
Start Date:	November 1, 2007
End Date:	October 31, 2010
Funding Amount:	$483,640.00
FHWA Program Name:	Innovative Pavement Research and Deployment
Goals:	The key project objective is reliable and effective pavement design.
Project Type:	Offsite

Expected Benefits:	The expected benefit is a fundamental understanding of why compaction is important to pavement performance and what factors need be considered to optimize in-place density, given the constituents of a given mix and other influencing factors, such as environment. The model may provide the ability to relate lab and field compaction. This should allow for improvements to be realized in the construction process that will contribute to extending pavement performance. The model should augment other ongoing efforts in the development of intelligent compaction roller equipment.
Deliverables:	Name: Research report. FHWA-HRT-10-065 Product Type(s): Research report Description: The deliverable is a report that describes the approach used to obtain the objective of developing a mathematical model that simulates the process of asphalt concrete compaction, and implementation of that model in a three-dimensional Finite Element Computational Platform.
