Brief description of the development and renewal of the mediarugosite and microroughness of road coatings.

摘要

The road surface to be roughened is hammered by the rotation of cylinders (15) arranged horizontally under a protective guard (1). The surface of the cylinders is covered with flexible tongues which pound the road and restore the roughness of particles between 1 and 200 micrometres. Several cylinders are joined together and their height is adjustable. The cylinders are pulled along by a tractor unit with a suction road sweeper attached behind. USE/ADVANTAGE - Method of renewing road surfaces which can be used in any weather. Fast, usable on specific areas which need treatment.
