TRB conducted a webinar on Thursday, April 7, 2016 from 2:00-3:30PM ET that featured two different research projects about asphalt mixes conducted by the
National Cooperative Highway Research Program (NCHRP). This webinar explored the effects of foaming on asphalt warm mix properties and the effects of aging on the behavior of asphalt mixes. This webinar provided an overview of both NCHRP research reports, emphasizing how they can be used by practitioners.

A certificate for 1.5 Professional Development Hours (PDHs) was provided to attendees who registered and attended the webinar as an individual. Contact Reggie Gillum at
RGillum@nas.edu for instructions on receiving a copy of the recorded webinar.
Here are the slides.
Webinar Presenters
- David Newcomb, Texas A&M Transportation Institute
- Edith Arambula, Texas A&M Transportation Institute
- Fan Yin, Texas A&M University
Moderated by: Ed Harrigan,
Transportation Research Board
Webinar Outline
- Overview of NCHRP Topic
- The effects of asphalt foaming on warm mix properties
- Determining the optimum water content for foaming asphalt to obtain desired coatability and workability
- Simulation of plant aging of asphalt mixtures
- Variables affecting aging and their effects on the behavior of asphalt mixtures in the laboratory and through plant production
- Question and answer session
The first 60 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 methods for measuring the performance-related properties of foamed asphalts
- Understand how to design foamed asphalt mixes with satisfactory aggregate coating and workability
- Discuss the variables affecting aging of asphalt mixtures
- List what factors have the largest impact on mixture properties and the protocol for aging laboratory mixtures

Professional Development Hour Information
A certificate for 1.5 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:
