Abstract

The invention discloses a polymer-modified cement concrete one-time paving forming method, which is characterized in that an asphalt paver with a high-density screed structure is used to make the thin-layer polymer modified cement concrete one-time paving and forming; The thickness of the polymer modified cement concrete thin layer is less than 40mm. The invention utilizes an asphalt paver to pave the polymer-modified cement concrete, and realizes one-time molding, without subsequent vibrating compaction by a vibrating bar or rolling compaction by a road roller, directly paving to form a smooth and rough surface.
