This Small Starts study offers sustainable road building materials for rural infrastructure, from an unlikely source. Approximately 7,000 years ago, the eruption of Oregon's Mt. Mazama blanketed the Klamath Basin region with a thick layer of volcanic ash. Matthew Sleep, an associate professor of civil engineering at Oregon Tech, investigated the use of this ash as a natural pozzolan for soil stabilization and unpaved roadway improvement. He found that the ash, prevalent in Southern Oregon, has… Read More

KersTech Vehicle Systems is in the process of creating a hybrid drive system combining a flat format hydraulic motor with an electric motor for energy recapture of vehicle momentum. The initial drive system is targeted at a specific vehicle application. A main component of the drive system being developed is a controller and the associated algorithm. The controller algorithm is a new adaptation of an optimally robust algorithm for model uncertainties and resilience against control feedback gain… Read More
