The invention discloses an environment-friendly rubber asphalt additive, environment-friendly rubber asphalt and a preparation method thereof. The environment-friendly rubber asphalt additive disclosed by the invention comprises the following components in parts by weight: 1-5 parts of modified PDA-tourmaline nanoparticles; 1-10 parts of a dispersant; the dispersing agent is selected from one or more of soybean oil, rapeseed oil, peanut oil, palm oil and sunflower oil; the size of the modified PDA-tourmaline nano-particles is 100-300 nm, and the surfaces of the modified PDA-tourmaline nano-particles are modified by a large number of hydroxyl groups. Through the in-situ trapping effect of the environment-friendly rubber asphalt additive, the amount of small molecular compounds released by the rubber asphalt due to the influence of high temperature is reduced, the environmental problems existing in production and construction of the rubber asphalt are solved, and the environment-friendly rubber asphalt additive
