In 1993, the South Dakota Department of Transportation initiated the Research Project SD93-14, Enhancement of South Dakota's Pavement Management System. As the Research Project progressed, it was determined that to better evaluate the condition of the pavement, a more detail distress survey needed to be performed by SDDOT. The Research Technical Panel identified the failure mechanisms for pavements that were prevalent and would trigger a rehabilitation or reconstruction project in South Dakota. |
