The invention discloses a method for producing road asphalt from catalytic slurry oil. The method comprises the following steps: mixing light catalytic slurry oil with atmospheric residual oil; then conveying the obtained mixture to a vacuum distillation tower for vacuum distillation; and uniformly blending improved vacuum residual oil from the bottom of the tower with heavy catalytic slurry oil at 130-150 DEG C until no layering occurs so as to obtain the road asphalt, wherein the mass of the light catalytic oil slurry is 1-7% of the atmospheric residual oil, and a mass ratio of the improvedvacuum residual oil to the heavy catalytic slurry oil is (6-7): (3-4). The asphalt prepared in the invention meets performance standards for No. 180 and No. 200 asphalt in petrochemical industry standards. The treatment method of the invention does not need to perform distillation cutting or modification via a modifier on the catalytic slurry oil, and the desired raw residual oil or catalytic slurry oil belongs to low-value by-products of raw petroleum; and production process is simple.
