Washboarding

Washboarding effect on a road

Washboarding or corrugation[1] is the formation of periodic, transverse ripples in the surface of gravel and dirt roads. Washboarding occurs in dry, granular road material[2] with repeated traffic, traveling at speeds above 8.0 kilometres per hour (5 mph).[3] Washboarding creates an uncomfortable ride for the occupants of traversing vehicles and hazardous driving conditions for vehicles that travel too fast to maintain traction and control.[4]
