ABSTRACT:
Apparatus and method for milling road surfaces wherein a motor driven rotatable roller, equipped with hard-metal cutters, is moved horizontally relative to the road surface, while support wheels, adjustable by individual screw jacks or hydraulic jacking cylinders, make it possible to adjust the vertical height of the end bearings of the roller with respect to the road surface. The roller is rotated in a direction opposite to the direction of forward movement of the axis of the roller relative to the road surface. That is, the cutters mill the road surface in a direction of forward movement of the axis of the roller.
