TRB conducted a webinar on Thursday, April 20, 2017 from 2:00 PM to 3:30 PM ET that featured research from the National Cooperative Highway Research Program
(NCHRP)’s Report 818
: Comparing the Volumetric and Mechanical Properties of Laboratory and Field Specimens of Asphalt Concrete.
This webinar discussed how to evaluate the causes and magnitude of variability of specimen types tested in quality control and/or assurance programs for asphalt paving projects. The presenters described a proposed practice for evaluating several different types of asphalt concrete.
A certificate for 1.5 Professional Development Hours (PDHs) was provided to attendees who registered and attended the webinar as an individual.

- Louay Mohammad, Louisiana State University
- Samuel Cooper III, Louisiana Department of Transportation and Development
Moderated by: Ed Harrigan, Transportation Research Board
- Overview of NCHRP project
- Proposed practice for evaluating the cause and magnitude of variability of specimen types
Question and answer session
- Laboratory mixed and compacted
- Plant mixed, laboratory compacted
- Plant mixed, field compacted
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.
At the end of this webinar, participants will be able to:
- Describe causes of variability and tolerances for volumetric and mechanical properties of dense-graded asphalt mixtures measured within and among the specimen types (laboratory-mixed and compacted; plant-mixed, laboratory-compacted; plant-mixed and field-compacted)
- Identify the proposed practice for evaluating the cause and magnitude of variability within and among the specimen types
- Apply the conversion factors between the specimen types of mechanical properties evaluated

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.
