TRB will conduct a webinar on Tuesday, October 30, 2018 from 2:00 PM to 3:30 PM ET that will discuss techniques for reducing pavement damage due to spring thaw, especially on low volume roads. These techniques include improving geometric design, properly posting spring load restrictions, and modifying drainage systems. Presenters will highlight case studies of mitigation techniques from Minnesota, New York, and Alaska. They will describe spring thaw and provide practical mitigation examples that can be implemented into new and existing pavements.

This webinar was organized by the TRB Standing Committee on Seasonal Climatic Effects on Transportation Infrastructure.

Some registrants will need to pay $95 to attend this webinar. Sign into MyTRB.org to view registration information.

Webinar Presenters

• Billy Connor, Alaska University Transportation Center
• Steve Henrichs, Minnesota Department of Transportation
• David Orr, Cornell Local Roads Program

Moderated by:  Ben Worel, Minnesota Department of Transportation

Webinar Outline

1. Description of the problem of freeze-thaw on the life span of the pavement
2. The effects of ice and snow melt accumulation during spring thaw period
3. How spring thaw affects infrastructure and appurtenances
4. Pavement thaw weakening and reduction in life
5. Alternative approaches from Minnesota, New York, and Alaska
6. 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:

• Predict spring thaw periods and how they change the damage characteristics of low volume roads
• Apply ideas from Minnesota, New York, and Alaska that address the problem
• Identify geometric design best practices for reducing ice/snow melt related problems

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 March 2018. 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.
