The invention discloses a coal pitch mixture, which comprises road coal pitch and mineral aggregate, wherein the weight ratio of the road coal pitch to the mineral aggregate is 6-3:94-97; the road coal pitch consists of the following components in percentage by mass: 10-80 percent of coal pitch, 15-76 percent of petroleum pitch, 3-8 percent of alkyl acid or alkyl acid salt and 2-6 percent of low molecular weight polyethylene. The invention also discloses a preparation method of the coal pitch mixture. The temperature of the coal pitch mixture is reduced by 20-30 DEG C during mixing and construction compared with hot mixed pitch mixture; the emission of pitch gas can be obviously reduced and the effect of suppressing the toxicity of the coal pitch is achieved; and thermo-oxidative aging ofthe pitch is reduced and the aims of energy conservation and emission reduction are fulfilled. The obtained coal pitch mixture is easier to compact; and indexes such as compactness, water stability, high temperature performance and low temperature performance of a paved pavement are not less than those of the hot mixed pitch mixture of the same grade.
