Along with proper surface drainage practices, provisions are needed to provide proper subsurface drainage for the removal of water from underneath the road surface. The North Dakota Department of Transportation (NDDOT), along with many other states, have utilized longitudinal underdrains (edge drains) to collect and dispose of water from the underlying pavement structure directly beneath the roadbed to eliminate moisture related pavement distress. In order to evaluate the effectiveness and long term operation of these edge drains, an optical camera was obtained to observe the interior of the edge drain piping. In performing the annual inspection of the edge drain systems, an evaluation of the optical camera system was also conducted to determine its performance and usefulness as a diagnostic tool for other applications.
