Inverted pavement is an effective design option that can enhance the sustainability and resilience of pavements. TRB hosted a webinar on Monday, September 18, 2023 from 2:00 PM to 3:30 PM Eastern that presented the structural mechanics and effective uses of inverted pavements. Presenters provided a summary of the state-of-technology. Presenters also shared case studies that discuss agency experiences during the design and construction of inverted pavements and the performance of inverted pavements compared with control sections.

This webinar was sponsored by TRB’s Standing Technical Committees on Mechanics and Drainage of Saturated and Unsaturated Geomaterials, Transportation Earthworks, and Geotechnical Instrumentation and Modeling.

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