TRB conducted a webinar on September 10, 2013 that explored a methodology to compare the effect of the new generation wide-base tires and dual tire assembly on flexible pavement damage. Contact Reggie Gillum at
RGillum@nas.edu for instructions on obtaining a link to the recording.
Webinar presenters will cover a brief history of wide-base tires (WBT) development and the environmental advantages of using WBT when compared to dual tire assembly (DTA). The webinar will discuss four main aspects:
- The importance of considering three dimensional (vertical, longitudinal and transverse) contact stresses for pavement modeling and response prediction
- Flexible pavement damage prediction utilizing pavement response and distresses
- Effect of WBT on various pavement structures and their corresponding response
- Impact of using WBT on pavement use cost.
The ongoing international efforts to evaluate the effect of WBT on pavement damage and expected outcome will be presented.
Webinar Presenters:
- Eric Weaver, Federal Highway Administration
- Imad Al-Qadi, University of Illinois, Urbana-Champaign
- Hao Wang, Rutgers, The State University of New Jersey
- Jaime Hernandez-Urrea, University of Illinois, Urbana-Champaign
Moderated by: Trenton Clark, Virginia Asphalt Association
Webinar Outline:
- Introduction: Eric Weaver
- Introduction and Background on Wide-Base Tires: Imad Al-Qadi
- Importance of Tire 3D Contact Stresses: Imad Al-Qadi
- Pavement Modeling and Impact of 3D Moving Tire Loading: Jaime Hernandez
- Failure Prediction Considering Contact Stress Variations: Hao Wang
- Cost Impact of Using Wide-Base Tires: Hao Wang
- Ongoing Work and Final Remarks: Imad Al-Qadi
The first 90 minutes of the webinar is for presentations and the final 30 minutes is reserved for audience questions.
Learning Objective:
- To learn about the impact of wide-base tires on pavements and a framework to determine pavement damage created by these tires
- To become aware of the mechanisms of contact stress distributions by each tire and the effect of axle load and tire pressure on the contact stresses
- To understand the appropriate numerical tools to capture the effect of each tire on thin and thick pavement responses
