The invention relates to asphalt, in particular to high-grade road asphalt prepared from coal tar pitch. The high-grade road asphalt comprises the following raw materials by part by weight: 30 to 70 parts of coal tar pitch, 15 to 30 parts of petroleum asphalt, 30 to 50 parts of solvent naphtha, 3 to 5 parts of composite polymer additive, 2 to 10 parts of antiager, and 0.3 to 0.5 part of cross linker. The high-grade road asphalt prepared from the coal tar pitch has the advantages as follows: the addition of the petroleum asphalt is reduced, and the usage amount of the coal tar pitch is increased; and the cost is reduced, and the performances of the road asphalt prepared from the coal tar pitch are improved, that is, the Engler viscosity of the asphalt is increased, the asphalt softening point is raised, the penetration degree is lowered, the high temperature stability is improved, the low-temperature ductility is greatly increased, and the low-temperature cracking resistance is remarkably improved.
