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.

Description

technical field [0001] The invention belongs to the technical field of concrete, and relates to a polymer modified cement concrete paving forming technology, in particular to a polymer modified cement concrete paving forming method at one time. Background technique [0002] Polymer modified cement concrete is modified by blending special polymer emulsion and various additives. The modified cement concrete has excellent toughness, impact resistance and crack resistance, and is a new material with excellent comprehensive road performance. [0003] Some scientific research institutes and experts and scholars at home and abroad have conducted research on polymer modified cement concrete pavement materials and their applications. Some scholars have studied the composite pavement structure of plastic polymer modified cement concrete and ordinary portland cement concrete, recommended the composite pavement structure combination, and studied the structural stress distribution, road...
