ABSTRACT:
Asphalt or concrete pavement is removed from a road bed by an elongated cutter blade that extends in a downward and forward direction along a cutting plane to a cutting edge. The cutting plane forms an acute angle of between 45.degree. and 55.degree. with the surface of the pavement. The cutter blade is intermittently driven with a force parallel to the cutting plane in the forward direction while the cutting edge penetrates the pavement to drive the cutter blade incrementally in a forward direction and plane off the pavement in a chisel-like manner. A source of vibrations is connected to one end of plural spaced apart resonant beams. At the other end, the beams drive the cutter blade.
