The invention discloses a preparation method of a pavement material, the prepared pavement material and application of the pavement material, and relates to the technical field of plant residue recycling and pavement materials. According to the pavement material, plant residues are collected as a main component of the pavement material, and the uncorrupted plant residues are crushed so as to obtain crushed plant residues; and anti-halogen-free bonding treatment is performed on the crushed residues so as to obtain the paving material which adopts the crushed plant residues as the main component. The method is simple, and has low cost, the anti-halogen phenomenon caused by application of magnesium chloride and magnesium oxide is reduced to a large extent, and the prepared pavement material has good flexibility, good comfort, high flexural strength, good water permeability and salt resistance, and can be applied to paving and use of ecological landscape construction and other projects.
