  • Patent number: 6592289
    Abstract: To make a concrete roadway; a continuous section of concrete is poured and cut at an angle of between 5 degrees and 45 degrees downwardly in the direction of traffic flow, to form an angled cut with an overlying surface that can be pressed downwardly by a vehicle to reduce movement of the concrete with respect to the sections on either side of a joint in the pavement. With this cut, vehicles will press a top layer downwardly against a bottom layer. A rotary saw blade mounted at an angle to the roadway is used to cut the concrete.
