TRB will conduct a webinar on Wednesday, October 31, 2018, from 2:00 PM to 4:00 PM ET that provides a practical discussion of moisture damage in asphalt pavements. The presenters will discuss real-world examples of how transportation agencies have investigated moisture damage in specific projects; useful cost-benefit considerations when addressing asphalt mixtures that may be susceptible to moisture damage; and the research needed to fill the current gaps.  The webinar mirrors a session from the 2018 TRB Annual Meeting.

This webinar was organized by the TRB Standing Committee on Surface Requirements of Asphalt Mixtures.

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

Moderated by: Tim Aschenbrener, Federal Highway Administration

Webinar Outline

  1. Introduction
  2. Fundamentals of moisture damage
  3. Forensic investigation of hot mix asphalt (HMA) raveling and moisture damage in Maine
  4. Evaluating performance of asphalt pavements in Arkansas
  5. Cost–benefit analysis of antistrip additives in HMA with various aggregates
  6. Moisture damage literature review and gap analysis for needed research
  7. Question and answer session

The first 90 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:

  • Identify moisture-related damage in asphalt pavements
  • Describe various methods to make asphalt pavements less susceptible to moisture damage and understand the steps to address moisture damage taken by state highway agencies
  • Discuss a cost-benefit analysis performed to determine the applicability of anti-strip additives
  • Discuss the existing research related to asphalt moisture damage and identify gaps

Professional Development Hour Information
