New Pavement Design Procedure Assessed
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?
