Abstract: A device for repair of a roadway embankment includes a movable base which is capable of being driven on a two-lane roadway. A platform is mounted on the base and is rotatable with respect to the base about a generally vertical axis. A drilling rig is mounted on one end of the platform for drilling a hole for receiving an elongate reinforcing rail, and a power unit is mounted at an opposite end of the platform for generating power for the drilling rig and for counterbalancing the weight of the drilling rig. The drilling rig includes a drilling bit and a compressor for generating a flow of air to remove the drilling cuttings. The length of the platform is such that the distance between the centerline of the drilling bit and the outer side of the closest supporting wheel allows the base to be located on a undamaged roadway and the drilling bit operated to drill a hole for receiving the reinforcing rail in the damaged portion.
