Details
TRB conducted a webinar on Monday, August 22, 2016 from 1:00PM to 2:30PM ET that discussed the construction of unbound aggregate layers. Roads last longer when unbound aggregate layers are built well. Because it is important to compact materials at the correct moisture levels, accurate and fast measurements of moisture and compaction during construction can improve quality and long term performance. This webinar discussed unsaturated geomechanics, which when considered during design and construction may lead to more economic designs. The webinar also examined the ways practitioners can assess a site and what actions they can take in the field. 

This webinar was requested by the TRB Standing Committees on Aggregates and Engineering Behavior of Unsaturated Geomaterials. 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 from the presentations.

Webinar Presenters
  • Claudia Zapata, Arizona State University
  • Erol Tutumluer, University of Illinois at Urbana-Champaign
  • John Siekmeier, Minnesota Department of Transportation
Moderated by: Andrew Dawson, Nottingham Transportation Engineering Centre

Webinar Outline
  1. Case studies on the application of unsaturated geomechanics principles
  2. Matric suction and moisture measurements collected at field sites and information about the spatial and temporal variation of these values
  3. Instrumentation available for monitoring matric suction and moisture content
  4. Laboratory and field testing equipment available for performing tests on unsaturated geomaterials
  5. Question and answer
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 the state-of-the-practice with respect to the compaction of unbound aggregate layers during construction
  • Identify the tools practitioners can use to evaluate and assess sites and the action steps they can take to implement solutions

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 March 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: www.RCEP.net.
