The invention discloses a method for preparing an asphalt micro-meso analysis sample by adopting a silicone mold. According to the technical scheme, the method comprises the steps of preparing a mold; heating and pouring; scraping by utilizing a heat knife; carrying out secondary heating; fixing a mold glass slide; cooling and demolding; testing and observing. The mold is prepared by utilizing the characteristics of no toxicity, no odor, stable chemical property, good elasticity, high tensile strength, high temperature resistance, easiness in forming and demolding, and the like of silicon, the prepared analysis sample has a smooth surface, is high in flatness and uniform in thickness, various analysis samples meeting different requirements can be obtained by adjusting the shape, specification and size of a sample preparation mold, so that the specification requirement of test instruments such as a scanning electron microscope, an atomic force microscope and the like for different analysis samples can be met. According to the method, the operation is convenient, the analysis sample forming efficiency is high, the consumption of asphalt is controllable, and the method is ideal for preparing the asphalt micro-meso analysis sample.
