ABSTRACT:
A pavement cutter is provided for attachment to the boom assembly of a conventional backhoe or excavator including an elongated cutting blade having a scoring edge disposed in substantially parallel relation to the surface of the pavement and a cutting edge disposed substantially perpendicular to the scoring edge and wherein a pair of outwardly extending pressure flanges are attached to the blade one on each thereof at a point above the scoring and cutting edges of the blade. The pavement is first scored along a straight line using the scoring edge and then cut along the scored line using the cutting edge of the blade. The pressure flanges on each side of the cutting blade slide along the top surface of the pavement applying a vertical or downward force which prevents the asphalt from lifting and breaking up during the cutting operation.
