Abstract
The screed plate apparatus and method has a road paver/finisher, screed plate, and material matting apparatus having a power source and structural/conductor plate. Paving material is loaded into the material matting apparatus and applied homogeneously as a paving mat to a road surface in a road paver/finisher travel direction. The structural/conductor plate is attached to the road paver/finisher and to the screed plate to provide indirect heat to the screed plate. The screed plate bottom side has differing forms of textured surface impacting the paving material, by differing corrugations of differing patterns, into a more homogeneous consistency. The corrugated pattern may be oriented parallel or perpendicular to the paver travel direction, and/or progressively flattening or set in a crisscross rhombic pattern. A vibrating and oscillating mechanism operates horizontally and vertically upon the screed plate providing a homogeneously sorting on the paving material.
