| description | The invention discloses composite modified asphalt doped with waste engine oil residues and polyphosphoric acid and a preparation method of the composite modified asphalt, belonging to the technical field of modified asphalt preparation. The composite modified asphalt doped with the waste engine oil residues and the polyphosphoric acid in the invention comprises the following raw materials in parts by mass: 100 parts of asphalt, 1-10 parts of the polyphosphoric acid, 1-30 parts of the waste engine oil residues and 1-15 parts of a flame retardant. The composite modified asphalt is prepared by the steps of preheating, premixing, shearing, development reaction, addition of the flame retardant and the like. According to the above technical scheme, a large amount of the waste engine oil residues can be recycled, the bottleneck problem restricting development of a waste engine oil processing industry is solved, processing cost is greatly saved, and pressure on environment and resources is relieved.
