Mount Mazama Ash Offers Sustainable Solution For Ada Accessibility On Unpaved Trails, Matthew D. Sleep, Damian K. Matzen

TREC Project Briefs

National Institute for Transportation and Communities (NITC) researcher Matthew Sleep of Oregon Tech investigated whether Mazama ash could be used in place of portland cement, as a natural pozzolan. Results indicate that it can—and unpaved trail surfaces made with Mazama ash are actually firmer and more durable than those made with portland cement alone. Such trails can provide a reliable surface for wheeled mobility devices.
