TRB conducted a webinar on Tuesday, March 8, 2016 from 2:00PM to 4:00PM ET that examined research conducted by University of Nevada, Reno as part of the Asphalt Research Consortium (ARC) sponsored by the U.S. Federal Highway Administration (FHWA). ARC developed a model for thermal cracking analysis in asphalt pavements. This webinar explored how this model’s modifications may remedy the limitations in the available thermal cracking models. Presenters discussed how this model may be utilized as a tool for selecting thermal cracking resistant asphalt mixtures at the location of interest. The Temperature Estimate Model for Pavement Structures (TEMPS) can be found at

Webinar Outline
- Introduction
- Oxidative aging of asphalt binders and influence on mixture characteristics
- Evolution of mixture properties with asphalt binder oxidation
- Estimation of asphalt binder oxidative aging during the pavement in-service life
- Thermal cracking analysis of asphalt mixtures using the Thermal Analysis Cracking Package (TCAP)

- Question and answer
The first 90 minutes of the webinar will be for presentations and the final 30 minutes will be reserved for audience questions. The Registered Continuing Education
Program (RCEP) categorizes this webinar activity as relating to health, safety, and welfare including core technical.
Learning Objectives
At the end of this webinar, participants will be able to:
- Understand the influence of aggregates and mixture factors on the binder oxidation
- Understand the change in the mixture properties with binder oxidation
- Understand the process for a thermal cracking analysis of asphalt pavements

Professional Development Hour Information
A certificate for 2.0 Professional Development Hours (PDHs) will be provided to Professional Engineers (PEs) who register and attend the webinar as an individual. For groups,
only the person that registers and attends the session will receive a PDH certificate.
Individuals registered as Florida PEs are no longer required to email TRB with your license number to report your attendance. Instead, please use your certificate that
TRB provides through RCEP.net as verification of your attendance to the Florida Board of Professional Engineers.
Please check with your licensing board to ensure that TRB webinar PDHs are approved by your board.
This webinar was developed in November 2015. TRB has met the standards and requirements of the Registered Continuing Education Program (RCEP). Credit earned on completion of this program will be reported to RCEP by TRB. Certificates of Completion will be issued to individuals who register for and attend the entire webinar session. Complaints about registered providers may be sent to RCEP, 1015 15th Street, NW, 8th Floor, Washington, DC 20005. Website:
