The invention discloses an engineering tire tread rubber composition as well as a preparation method and application thereof, and belongs to the technical field of engineering tires. The formula of the rubber compound comprises the following components in parts by weight: 0-100 parts of butadiene styrene rubber, 100-0 part of natural rubber, 10-65 parts of carbon black, 5-55 parts of white carbon black, 0-10 parts of a silane coupling agent, 1-10 parts of zinc oxide, 1-5 parts of stearic acid, 0-4 parts of microcrystalline wax, 1-8 parts of an anti-aging agent, 0.5-12 parts of heat dissipation filler, 0.2-6 parts of a low heat generation agent, 0.1-6 parts of an anti-cutting agent, 0.1-5 parts of sulfur and 0.1-6 parts of an accelerant. According to the engineering tire tread rubber composition disclosed by the invention, the heat dissipation filler, the low heat generation agent and the anti-cutting agent are added, so that the properties of heat conduction, heat dissipation, cutting resistance, gnawing resistance, chunking and chipping resistance, fatigue resistance and the like of a rubber material are effectively improved, the dynamic heat generation of the rubber material is very low, and the physical and mechanical properties required by the rubber material are not influenced.
