The invention belongs to the technical field of rubber, and particularly relates to a tire tread rubber composition and an application thereof. The invention discloses a tire tread rubber compositionwhich comprises the following raw materials in parts by weight: 50-80 parts of natural rubber, 20-40 parts of butadiene rubber, 2-8 parts of stearic acid, 15-25 parts of a modified filler, 40-60 partsof carbon black, 2-8 parts of aromatic hydrocarbon oil, 0.5-3 parts of a vulcanizing agent and 1-6 parts of an accelerant. Under the combined action of the components at a certain ratio, the tire tread rubber composition has high aging resistance and mechanical properties, the driving control safety of the tire on the road surface can be improved, the rolling resistance can be reduced, and the wear resistance can be improved.
