ABSTRACT:
A portable screed for smoothing and leveling an area of freshly poured concrete. The screed includes a cylindrical, horizontal smoothing roller secured to the screed plate for the screed, the roller being substantially coextensive with the screed plate. The roller is mounted immediately adjacent the screed so that the roller first encounters and smooths concrete before the screed plate passes over the concrete. The roller is adjustable to control its working of the concrete, and rotates about its axis in a direction opposite to the direction of travel of the screed for proper smoothing of the concrete.
