  • Apparatus for maintenance of a gravel road
    Patent number: 5052853
    Abstract: Apparatus for smoothing a gravel road comprises a mat which incorporates a series of wave-form members, typically of flexible material such as rubber. The mat is towed over the road surface with the result that the crests of the wave-form members dig into corrugations in the surface and disturb the gravel. The disturbed gravel can flow upwardly through the spaces between the wave-form members.
