Project ID:	FHWA-PROJ-09-0025
Project Name:	Pavement Shear Strain Response To Dual and Wide-Base Tires
Status:	Active
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:	Analyze data from instrumented pavement sections having been loaded by a truck equipped with both dual- and wide-base tires in hot weather conditions. The data was collected from the Specific Pavement Study (SPS)-8 sections at the Ohio Test Road. Data would be used to show relative shear strains induced near the pavement surface to validate existing models for use in next-generation Mechanistic-Empirical pavement design. This could lead to more reliable performance prediction, especially with regard to longitudinal cracking.
Laboratories:	Not Applicable
Start Date:	August 3, 2009
End Date:	September 30, 2011
Funding Amount:	$72,000.00
FHWA Program Name:	Eisenhower Fellowships
Goals:	The key objective is to determine differences in the asphalt concrete shear strain response in hot weather, resulting from different tire configurations under the same loading.

Expected Benefits:	The expected benefit is validation of pavement models using real data. The investment in the data collection has already been made by the Federal Highway Administration (1998), but the data were never processed and analyzed. Early research at the Accelerated Pavement Testing Facility suggested that the wide-base tires in use at the time produced more pavement damage than dual tires; however, the experiments were never repeated with newer designs. The wide-base tires included in this experiment used both the type of tire used at the Accelerated Pavement Testing Facility and a new prototype tire shipped from France by Michelin. These experiments may reveal the relative strains induced by each tire type and design. This work is meant to compliment graduate work on the three-dimensional (3D) finite element method (FEM) tire model under Rey Roque at the University of Florida, 3D FEM pavement modeling by Imad Al-Qadi at the University of Illinois, and the Vehicle-Pavement Interaction work by Peter Sebaaly as part of the Asphalt Research Consortium at the University of Nevada—Reno.
