The history of pavement deflections affects their future. TRB hosted a webinar on Wednesday, June 24, 2020 from 1:00 PM to 2:30 PM Eastern that discussed current pavement deflection testing methods and evaluation procedures. Presenters described the historical background of pavement deflection as well as the current and future status of moving deflection devices. They identified non-destructive testing devices, backcalculation methods and challenges, and devices for measuring pavement deflections.

This webinar was organized by the TRB Standing Committee on Pavement Structural Modeling and Evaluation.

The slides are available. Contact Reggie GIllum for a copy of the recorded webinar.
