TRB conducted a webinar on January 30, 2013, from 12:00 p.m-2:00 p.m ET that provided an overview of potential risks for enhanced moisture-induced damage and practices for preventing damage by examining pavements used in Europe and the United States. Contact Reggie Gillum at
RGillum@nas.edu for details to access a link to the recorded webinar.
Moisture-induced damage in asphalt concrete wearing surfaces may have detrimental consequences for the long-term mechanical performance and safety of pavement. Even though this problem has been acknowledged for some time, many aspects of it are unknown and, as a consequence, current characterization methods are not producing reliable predictions of moisture-susceptibility. In addition, there are many concerns and questions regarding the moisture-induced damage performance of warm-mix asphalt mixtures due to the lower mixing and compaction temperatures.
This webinar was organized by the TRB Standing Committee on Characteristics of Bituminous-Aggregate Combinations to Meet Surface Requirements,
AFK40.
Webinar Presenters:
- Niki Kringos, KTH Royal Institute of Technology, Sweden
- Sandra Erkens, Dutch Ministry of Infrastructure and Environment
- Munir Nazzal, Ohio University
- Robert B. McGennis, The HollyFrontier Companies
Moderated by: Dr. Louay Mohammad, Louisiana State University, Louisiana Transportation Research Center
Webinar Outline:

- Moisture-Damage – Relevance, Past Experience and Current Practice in the Netherlands, Sandra Erkens
- Use of AFM to Characterize Moisture-Damage, Munir Nazzal
- Designing Against Moisture-Intrusion, Robert B. McGennis
The final 30 minutes of the webinar is reserved for audience questions.
