High-strength pavement material and preparation method thereof

The invention discloses a high-strength pavement material and a preparation method thereof, and relates to the technical field of building materials. The high-strength pavement material is prepared from the following components in parts by weight: 5-10 parts of petroleum asphalt, 4-8 parts of polar plant fiber, 1-5 parts of modified coal-based activated carbon, 10-15 parts of cement, 10-15 parts of epoxy resin, 10-20 parts of a curing agent, 1-5 parts of a reinforcing agent, 1-3 parts of a light stabilizer, 200-250 parts of filler and 15-20 parts of water. The petroleum asphalt, the epoxy resin, the curing agent and the reinforcing agent are mutually matched to form a reticular three-dimensional polymer, the filler is enclosed in the reticular body, and structural stress is dispersed by the polar plant fiber, so that the pavement strength is enhanced; the modified coal-based activated carbon has the advantages that the plant fiber is prevented from being gathered together, dispersibility of the polar plant fi
