Pouring type cold-mixed pavement material
The invention provides a pouring type cold-mixed pavement material. The pavement material comprises emulsified asphalt, a coupling agent, dry materials and water, wherein the dry materials include rough aggregate, fine aggregate, cement, fibers, waste rubber powder, a water-reducing agent, an expanding agent, a demulsifier and an accelerating agent. The pouring type cold-mixed pavement material has appropriate and adjustable modulus, and is excellent in high-temperature stability, limit deformation capability and water damage resistance capability; the pouring type cold-mixed pavement material can be cast by adopting a single-layer structure, the thickness can be controlled at 6-8cm, the technology is simple, the cost is low, and the deformation follow-up property with steel (box girder) bridge surfaces is excellent, and the traffic can be opened after 2h; the paving is integrally stressed, and the defects of shift between layers of a double-layer structure, disease and damage due to stress of thin layers can be avoided, and the pouring type cold-mixed pavement material has good durability.
