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 webinarSign into 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
