ULTRA-HIGH-PERFORMANCE CONCRETE PAVEMENT STRUCTURE AND CONSTRUCTION METHOD THEREOF

摘要

Disclosed in the present invention are an ultra-high-performance concrete pavement structure and a construction method thereof. The structure is a composite structure of combining layers. A steel panel base layer (1) is sequentially provided with a composite shear-resistant adhesive layer (2), a high-density fiber concrete layer (3), an epoxy high-viscosity layer (4), a high-toughness resin mortar layer (5) and an anti-sliding wearing layer (6) thereon. The composite shear-resistant adhesive layer (2) consists of a high-toughness resin, basalt rubble and a high-strength interface binder. The high-density fiber concrete layer (3) is formed by combining high-density fiber concrete precast slabs. The high-density fiber concrete precast slab is prepared by disposing a sparse reinforcing steel mesh (9) in the high-density fiber concrete. The pavement structure has high stability, avoids defects at interface junctions, reduces the weight, improves the anti-crack performance and ductility of a steel deck, facilitates on-site construction and ensures the uniformity of steel deck pavement structures.
