[0002] Ultra-high performance concrete is a new type of concrete material with extremely high compressive strength, durability and impermeability. Compared with traditional concrete, ultra-high performance concrete has better performance. It has the advantages of high compressive strength, high flexural strength, strong density and good durability. Ultra-high performance concrete is usually used in bridges, tunnels, buildings, marine engineering and protective components to provide super structural performance and durability. It is regarded as an important technological innovation in the field of concrete and has been widely used in construction projects and infrastructure construction.

[0003] For example, a utility model patent with announcement number CN219385860U discloses an ultra-high performance concrete composite bridge deck pavement structure, which relates to the technical field of bridge deck pavement. The utility model has a main body structure, which includes a load-bearing layer, and ultra-high performance concrete blocks are bonded and laid on the upper surface of the load-bearing layer; a reinforcing mechanism, which is fixedly installed on the upper surface of the ultra-high performance concrete blocks, includes a waterproof layer, and a drainage ditch is fixedly installed on the upper surface of the waterproof layer, wherein the drainage ditch has a certain slope, and asphalt is laid on the upper surface of the drainage ditch; the main body structure also includes a plurality of transverse steel bars fixedly installed on the upper surface of the load-bearing layer, and the plurality of transverse steel bars are fixedly connected to the ultra-high performance concrete blocks. The utility model provides an ultra-high performance concrete composite bridge deck pavement structure, in which glass fiber is laid on top of the concrete sealing layer. The glass fiber has good elongation and toughness, can resist cracking well, and reduces the risk of cracks in the bridge deck.

[0004] The device discharges water that penetrates the asphalt through the drainage grooves, thereby waterproofing the paving layer and preventing moisture from penetrating into the reinforcement structure and the main structure.

When there is too much rain from the outside, it is easy to enter the drainage grooves and affect the asphalt pavement. Therefore, an ultra-high performance concrete composite bridge deck pavement layer structure is provided. Utility Model Content
