How can you make the most of unpaved road designs? TRB hosted a webinar on Thursday, July 21, 2022 that will demonstrated a web-based material blending tool for designing unpaved roads. The tool is also useful for converting distressed low-volume paved roads to engineered unpaved roads. Presenters provided step-by-step instructions for using the tool and discussed how to interpret the results.

This webinar was sponsored by the TRB Standing Technical Committees on Low-Volume Roads and Aggregates.

The slides and recording are available.
