Abstract
A rotary grooving or grinding drum is mounted about a drive shaft. The drum has an inner core of steel, an intermediate sleeve of neoprene rubber and an outer sleeve of steel. The neoprene intermediate sleeve provides absorption of the shocks, jars and harmonic vibrations that the drum undergoes during use. The exterior surface of the outer sleeve is provided with a plurality of cutting segments disposed in a particular configuration depending on whether it is desired to groove or grind the surface of the concrete or asphalt pavement. Each cutting segment or group of segments may be separately removable mounted on the exterior surface of the outer sleeve so that worn out cutting segments can be individually replaced.
