description The invention discloses waste rubber powder/waste plastics/SBS composite modified asphalt and a preparation method thereof, wherein the waste rubber powder/waste plastics/SBS composite modified asphalt comprises the following ingredients in mass percent: 80 to 88 percent of substrate asphalt, 5 to 15 percent of waste rubber powder, 1 to 5 percent of waste plastics, 1 to 3 percent of SBS and 0 to 0.5 percent of cross linking agents. The preparation method comprises the following steps: heating the waste plastics at the temperature between 120 and 150 DEG C to be dissolved into the substrate asphalt; then, raising the temperature to 180 to 200 DEG C; proportionally adding the waste rubber powder, the SBS and the cross linking agents; and stirring and dispersing the materials for 0.5 to 3.0 hours under the simple stirring conditions to obtain the rubber powder/waste plastics/SBS composite modified asphalt. The invention has the advantages of environment protection, energy saving, low cost, simple equipment, easy
