ABSTRACT:
A self-propelled apparatus and method are disclosed for screeding placed and/or poured, uncured concrete or like loose, spreadable materials without use of prepositioned guides or rails. The apparatus includes a frame supported on hydraulically drive, steerable wheels, a cantilevered boom mounted on the frame, and a hydraulically driven, auger-type, vibratory screed either fixedly mounted or mounted for movement along the boom to spread and smooth the concrete as the screed is moved toward the vehicle. Screed control means are included for automatically adjusting the elevation of the screed relative to a laser beacon reference plane positioned off the apparatus such that the finished height of the concrete or other material is controlled within close tolerances. Preferably, the boom is rotatably mounted on the frame and also may be extended and retracted to properly position the screed and ease movement of the vehicle around fixed obstacles. The boom may also be pivoted vertically for screeding sloped surfaces. The method includes propelling the vehicle through uncured concrete or like material while screeding behind the vehicle. Also encompassed is the method of screeding by moving the screed toward the vehicle at a controlled rate.
