The invention discloses a preparation method of high-temperature-stable storage-resistant wheel-sticking-free emulsified asphalt, and aims to solve the technical problems that emulsified asphalt is difficult to store and wheel sticking is caused under a high-temperature condition. The high-temperature-stable storage-resistant wheel-sticking-free emulsified asphalt is prepared from the following effective components in percentage by weight: 45 to 55 percent of mixed asphalt, 0.3 to 0.6 percent of emulsifier, 0.1 to 0.4 percent of stabilizer, 2 to 6 percent of surface modifier and 38 to 51.6 percent of water, wherein the mixed asphalt is composed of 70 # matrix asphalt and low-grade asphalt according to the mass ratio of 1: (1.5-4). The high-temperature-stable storage-resistant wheel-sticking-free emulsified asphalt provided by the invention can solve the problem of wheel sticking of an emulsified asphalt sticking layer and a construction vehicle at a high temperature, has relatively good storage stability, and
