ABSTRACT:
An apparatus for cutting slots in pavement has a slot cutting assembly with several pairs of rotating blades mounted to a vehicle and vertically adjustable relative to the vehicle. A lift system moves the vehicle between a first position wherein the lift is not engaging the ground and a raised position wherein the lift engages the ground. A slider assembly uses a hydraulic to move the vehicle horizontally on rails relative to the lift when the vehicle is at the raised position. In operation, the vehicle is lifted and the cutting assembly lowered so the blades engage the pavement. The vehicle slides back and forth on the rails as the blades cut slot pairs. The material between each slot pair is removed to form a recess receiving reinforcement devices.
