Tensile strain, or strain from heavy loads, causes pavement to crack. But innovations in pavement design aim to reduce such damage. Currently, the Oregon Department of Transportation (ODOT) is in the process of adopting a new pavement design procedure. This involves examining data from existing pavement to predict how much cracking will likely occur in the new pavement. Analysts have already made predictions about how much tensile strain will occur in the new pavement using a procedure known as layered elastic analysis. Dr. Todd Scholzís project gathered key data in order to assess the validity of these key predictions. Want to learn more?

Faculty from all four OTREC partner campuses participated in the 2008 Northwest Transportation Conference at Oregon State University February 5-7. Under the theme of "Making the Most of What We Have: Innovations for the 21st Century," faculty served as session moderators and as roundtable members for a variety of topics. Portland State University attendees included Jennifer Dill, Peter Dusicka, Miguel Figliozzi, Hau Hagedorn, Chris Monsere, Tony Rufolo, Kristin Tufte and Brent Zenobia. University of Oregon faculty attending were Nico Larco, Marc Schlossberg and Yizhao Yang. Faculty from Oregon State University included Karen Dixon, Chris Higgins, Starr McMullen, Todd Scholz, Michael Scott and Lei Zhang. OTREC Associate Director Roger Lindgren from the Oregon Institute of Technology also attended. More information about the conference and program sessions: NWTC.
