TRB conducted a webinar on Thursday, March 30, 2017 from 2:00 to 3:30 PM ET that featured research from the
National Cooperative Highway Research Program (NCHRP)’s
Synthesis 492: Performance Specifications for Asphalt Mixtures.
This webinar explored performance tests for volumetric properties of asphalt mixtures. Performance tests are intended to extend service life by guiding material selection – including asphalt binder and aggregate – and proportions, such as asphalt content and gradations. The presenters explained how agencies are defining and assessing the performance of asphalt mixtures.
Participants must register in advance of the webinar, and there is a fee for non-TRB Sponsor or non-TRB Sustaining Affiliate employees. 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.
The
slides are available.

Webinar Outline
- Overview of NCHRP project
- Use of performance specifications for asphalt mixtures
- Development and implementation of low temperature cracking performance specification in Minnesota
- Low temperature cracking and properties of asphalt mixtures that are correlated to cracking amounts
- Development of low temperature cracking performance specifications through national pooled fun studies
- Specification refinement and round robin study for implementation
- Current efforts and future outlook
- New Jersey’s experience with asphalt mixture performance
- Performance tests in NJ using asphalt mixture testing
- NJ asphalt mixtures with performance test requirements
- Comparison of asphalt mixtures using lab test data
- Field performance of asphalt mixtures
- NJ’s future with asphalt mixture performance specifications
- 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 the most prevalent performance tests used for asphalt mixtures
- Understand what type of laboratory measured properties and field studies are needed for developing performance specifications
- Describe the process of implementation of a performance specification
- Understand how performance tests can be applied to any agency specification

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 October 2016. 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:
