ABSTRACT:
A roadway surface patching vehicle is described wherein virtually all roadway patching procedures may be performed by a single operator within a control station of the vehicle unit. The vehicle includes a number roadway repair tools mounted to a moveable carriage on the vehicle frame. This carriage is situated intermediate the control station and the front vehicle wheels. Among the operative tools are a cutter head and a vacuum head adjacent to the cutter head for receiving and directing loose particulate roadway surface material to a storage hopper for subsequent reblending and reuse. The vacuum head may also be used to clean the area adjacent the repair following placement and finished tamping and rolling of the new repair materials. A tamping head is also mounted to the carriage for movement therewith and a roller is mounted to the frame for finishing the repair to grade. A spread flame torch is provided on the carriage to heat the prepared cavity, melt ice, or dry the area in the vicinity of the cavity to facilitate reception of the roadway repair material therein. A tack coat spray nozzle is also situated to spray the cavity walls prior to reception of the repair material. All tools may be mounted to a turret on the carriage to be selectively rotated into view prior to operation. All operations involved in preparing the cavity and effecting the repair may thus be performed within full view of the operator station and by a single operator.
