Maintenance of Highway Edgedrains

Maintenance is required to keep pavement subsurface drainage open so that the pavement structure will drain. Just about all State highway agencies (SHA’s) that have constructed subsurface drainage systems recognize that maintenance is a problem. Vegetative growth around the pipe outlets, rodents' nests, mowing clippings, and sediment collecting on rodent screens at headwall are common maintenance problems. Some outlets have been so plugged that water has gushed from the pipes when they were unplugged. The purpose of this paper is to identify maintenance problems with edgedrains and document FHWA attempts at stressing the importance of maintenance to State highway agencies.
