Laboratory testing and field experience have shown that highway concrete should be properly air entrained to resist the action of freezing and thawing, particularly in wet climates. TRB will host a webinar on Tuesday, October 26, 2021 from 1:00-2:30 PM Eastern that will investigate requirements for the air-void system parameters of concrete used in highway pavements and structures. Presenters will discuss the proposed modifications to the current AASHTO test methods for evaluating concrete resistance to freezing and thawing. They will also examine innovative test methods to effectively characterize the air system in fresh concrete and identify the characteristics of the air-void system that are related to the performance of field concrete under freeze-thaw conditions.

This webinar features research from NCHRP Research Report 961: Entrained Air-Void Systems for Durable Highway Concrete.

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

Webinar agenda and presenters

  1. Laboratory investigation of alternative test methods for air void systems: Peter Taylor, Iowa State University
  2. Field review of pavement performance as a function of air void systems: Hamed Sadati, California Department of Transportation
  3. Laboratory investigation of alternative freeze-thaw tests on hardened concrete: John Kevern, University of Missouri, Kansas City
  4. Question and answer session: Peter Taylor, Iowa State University

The first 60 minutes of the webinar will be for presentations and the final 30 minutes will be reserved for audience questions.

Learning Objectives

At the end of this webinar, participants will be able to:

  1. Identify requirements for the air-void system parameters of concrete
  2. Discuss innovative test methods for effectively characterizing the air system

Professional Development Hour Information

Professional engineers (PEs) who register and attend the entire webinar as an individual will be awarded 1.5 Professional Development Hours (PDHs). TRB’s webinar program awards PDH credits only to the registered individual, and not to other members of a group that view the webinar together. To be eligible for the credits, individuals must remain signed in for the entire webinar, including for any question and answer session following the presentations.

Please check with your licensing board to ensure that TRB webinar PDHs are approved by your board.

TRB will report credits earned to the Registered Continuing Education Program (RCEP). Complaints about registered providers may be sent to RCEP, 1015 15th Street, NW, 8th Floor, Washington, D.C., 20005.

Pre-registration is required. Once the webinar starts, you will be unable to register. Individuals that are registered for a webinar but do not receive their confirmation emails due to their organization’s internal firewalls should contact the TRB Helpdesk for assistance in signing in.
