The invention relates to a high-performance non-slip geotextile and a preparation method thereof. The geotextile comprises a base layer and a bottom layer, wherein the base layer is woven with warp and weft, wherein the bottom layer comprises a polyimide fiber, a glass fiber, and a high-strength fiber which are interwoven by acupuncture and heat setting after opening, mixing, combing and lapping, and the weight ratio of the polyimide fiber to the glass fiber to the high-strength fiber is 4 to 4 to 2; non-slip spot-shaped particles are arranged on the upper surface of the base layer and the bottom part of the bottom layer. The geotextile has excellent mechanical properties, relatively strong tensile strength and resistance to deformation, and good corrosion resistance, and plays strengthening, anti-seepage, and anti-reflective crack effects in transformation of pavement, and the service life of the pavement is further prolonged.
