TRB will conduct a webinar on Thursday, July 27, 2017 from 2:00PM to 3:30PM ET that describes ways to use geofoam to address slope stability problems. Presenters will provide information about the design methodology of geofoam and an overview of construction practices. Presenters will also review the standards for the use of geofoam in slope stability applications. The results of this research can be found in NCHRP Research Digest 380: Guidelines for Geofoam Applications in Slope Stability Projects.

This webinar was organized by the TRB Standing Committees on Transportation Earthworks; Soil and Rock Properties; and Geosynthetics.

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