Patent

CA 2230558

A screeding assembly and method is disclosed for spreading, grading, consolidating and smoothing loose or plastic material such as poured, uncured concrete when the assembly moved over an area of the material. The assembly includes a rotatable auger to move the material laterally across the path of travel, a vibratory screed positioned behind the auger to smooth and finish the material, and an elongated engaging member reciprocated laterally across the path at a position between the auger and vibratory screed to facilitate consolidation of the material. Preferably, a plow/striker is positioned in front of the auger to and remove excess material. The assembly may be mounted on a self-propelled vehicle or other support on a boom for moving the assembly over the material, and is preferably controlled by a laser beam responsive elevation control. A kit for attaching the reciprocating engaging member to an existing screed assembly is also provided.
