Engineers are limited in their ability to adapt and mitigate asphalt pavements’ vulnerability to moisture damage. Climate models favor increased atmospheric moisture, adding urgency behind the need to understand effective countermeasures. TRB hosted a webinar on Wednesday, October 16, 2024 from 1:00 PM to 2:30 PM Eastern that examined the current state of the knowledge and critical knowledge gaps with respect to asphalt pavement moisture damage. Presenters covered basic mechanisms related to moisture damage, examined experimental methods, and presented current models for evaluating moisture damage impacts.

This webinar was sponsored by TRB’s Standing Technical Committee on Asphalt Mixture Evaluation and Performance.

The slides are linked in the meeting materials. View the recorded webinar below.

Webinar agenda and presenters

1. Overview of understanding the essential mechanisms – Silvia Caro, Universidad de los Andes

2. Moisture damage experimental methods – Gordon Airey, University of Nottingham

3. Moisture damage modeling – Eyad Masad, Hamad Bin Khalifa University

4. Question and answer session moderated by Jaime Hernandez, Marquette University

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

Learning Objectives

At the end of this webinar, participants can:

1. Describe the essential mechanisms that induce and promote moisture damage in asphalt concrete mixtures

2. Identify challenges and capabilities in current experimental methods and models that are used for measuring and predicting moisture damage

3. Establish the need for experimental methods and models that can assess the impact of extreme moisture events on pavements
