TRB will conduct a webinar on Monday, September 10, 2018, from 2:00 PM to 3:30 PM ET that features research from the National Cooperative Highway Research Program (NCHRP)’s Research Report 877: Performance-Based Mix Design for Porous Friction Courses.

This webinar will provide guidelines for a performance-based mix design procedure for porous friction courses (PFC) that includes laboratory testing. A project survey of PFC found that raveling and cracking were the primary distresses of PFC pavements, but tests to evaluate resistance to raveling and cracking were not typically included in agencies’ PFC mix design procedures. This webinar will present research results that evaluated the effect of asphalt modifiers and increased mineral filler for enhancing PFC performance. Presenters will also describe a PFC mix design procedure that addresses rutting.

Some registrants will need to pay $95 to attend this webinar.  Sign into to view registration information.

Webinar Presenters

  • Don Watson, National Center for Asphalt Technology
  • Nam Tran, National Center for Asphalt Technology
  • Adam Taylor, National Center for Asphalt Technology
  • Tommy James, Advanced Materials Services, LLC

Moderated by:  Michael Heitzman, National Center for Asphalt Technology


Webinar Outline

  1. Overview of NCHRP
  2. Factors affecting the performance of PFC pavements
  3. Evaluation of mix designs from good and poor-performing products
  4. Effect of increased mineral filler
  5. Effect of binder modification
  6. Performance-based mix design procedure
  7. Conclusions and recommendations
  8. 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:

  • Identify laboratory test procedures that can evaluate mix performance to resist raveling, cracking, and rutting
  • Evaluate potential enhancement of PFC performance with other materials
  • Determine needed revisions to agency PFC mix design procedures to improve performance

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. Certificates of Completion will be issued only to individuals who register for and attend the entire webinar session.

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 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 October 2017. 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. Complaints about registered providers may be sent to RCEP, 1015 15th Street, NW, 8th Floor, Washington, DC 20005.
