The invention discloses an asphalt compound modification testing method. The method comprises the following steps: S1, testing the softening point of conventional asphalt and SBS modified asphalt under different lake asphalt parameters; S2, testing the needle penetration of conventional asphalt and SBS modified asphalt under different lake asphalt parameters; S3, testing the ductility of conventional asphalt and SBS modified asphalt under different lake asphalt parameters; and S4, testing the viscosity of conventional asphalt and SBS modified asphalt under different lake asphalt parameters. The method has the technical effects that the effect of improving the softening point by adding lake asphalt is not remarkable; and the needle penetration can be constantly reduced by increasing the dosage of lake asphalt; the ductility of either SBS modified asphalt or conventional asphalt can be reduced after being doped with lake asphalt; and SBS modified asphalt doped lake asphalt has better effect from the aspect of i
