Multi-scale evaluation method for storage stability of asphalt cold supplementing liquid

The invention discloses a multi-scale evaluation method for the storage stability of asphalt cold supplementing liquid, which is characterized by comprising the following steps of: firstly, carrying out multi-scale evaluation analysis on the storage stability of the cold supplementing liquid from two dimensions of macroscopic evaluation and microscopic evaluation respectively; performing comprehensive evaluation on the storage stability of the cold fluid infusion according to a macroscopic evaluation test result and a microscopic evaluation test result; the macroscopic evaluation is used for evaluating by utilizing the kinematic viscosity difference of the upper part and the lower part of the cold supplementing liquid stored in the aluminum pipe; the microscopic evaluation is that an XD type fluorescence microscope is used for testing, and the dispersion uniformity of the polymer in the asphalt and the formed cross-linking state are observed. The method is easy to operate and low in cost; optimization is carr
