The invention discloses a common-type road surface seam sealant and a preparation method thereof. The seam sealant is prepared from AH-90 asphalt, SBS, a cosolvent, a stabilizing agent, a modifier, asoftener, granite ore powder, resin and waste rubber powder. In the seam sealant, a very low quantity of SBS, in certain block ratio and molecular weight, is added to greatly increase the high-temperature stability and low-temperature ductility of the seam sealant. By adding a large quantity of the granite ore powder and waste rubber powder, effects of improving the low-temperature ductility and anti-aging performance and greatly reducing cost of the seam sealant are achieved. Due to addition of a modifier, the chemical stability of the whole material system is enhanced, and further the low-temperature ductility of the seam sealant is improved; by means of addition of resin, adhesion force between the seam sealant and a seam is greatly improved.
