Details
TRB conducted a webinar on Thursday, September 10, 2015 from 2:00 PM to 4:00 PM ET that provided information about a modified asphalt design, called Superpave5, as it relates to research from the American Association of State Highway and Transportation Officials (AASHTO) M323. Superpave5 designs and constructs asphalt mixtures at 5% air voids, which may enhance mix design and in-place density requirements. This webinar also presented the results of two field trials using this technique.

This webinar was organized by the TRB Standing Committee on Flexible Pavement Construction and Rehabilitation.

A certificate for 2.0 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 from the presentations.


Webinar Presenters
  • Gerry Huber, Heritage Research Group
  • John Haddock, Purdue University
  • Matt Beeson, Indiana State Department of Transportation
Moderator: Lee Gallivan, Gallivan Consulting, Inc.


Webinar Outline
  1. Presentation of principle of constructing asphalt mixture to the same compaction level as the mix design
  2. Description of research of how to modify current design requirements in AASHTO M323
  3. Description of construction of experimental mixtures including production, placement and compaction
  4. Explanation of results of the comparison of road cores taken from regular and experimental mixtures
  5. Question and answer session
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 were able to:
  • Understand tools that may advance the quality of asphalt pavements
  • Understand how Superpave5 concepts may be implemented into the process for mixture design and construction compaction specifications
  • Understand how to apply AASHTO mixture volumetric requirements with the use of Superpave5 concepts
