Abstract

The invention relates to the technical field of asphalt production, and provides a rubber powder and asphalt compatibility control method, which comprises a step of training a compatibility control model, and specifically comprises the following steps of: acquiring a plurality of groups of sample data, wherein each group of sample data comprises rubber powder fineness, rubber powder mixing amount, stirring time, reaction temperature, development time and modified asphalt softening point difference values which are in one-to-one correspondence, and the rubber powder fineness, the rubber powder mixing amount, the stirring time, the reaction temperature and the development time are five influence factors of the compatibility of modified asphalt; extracting one hundred groups of sample data from the plurality of groups of sample data by adopting a Latin hypercube sampling method; and establishing a compatibility control model, and training the compatibility control model by taking sampling results of the rubber powder fineness, the rubber powder mixing amount, the stirring time, the reaction temperature and the development time as input data and taking a sampling result of the modified asphalt softening point difference values as output data. According to the rubber powder and asphalt compatibility control method, the problems that blindness exists in preparation of rubber asphalt and the product quality cannot be effectively controlled in related technologies are solved.

Description

technical field [0001] The invention relates to the technical field of asphalt production, in particular to a method for controlling the compatibility of rubber powder and asphalt. Background technique [0002] Asphalt mortar is composed of asphalt and fillers, and the quality control of the compatibility between modifier (rubber powder) and asphalt has not been comprehensively and systematically studied in China. The compatibility between modifier (rubber powder) and asphalt is an important index to evaluate the performance of rubber asphalt. The Texas Department of Transportation has found that as the rubber modifier (rubber powder) becomes thinner, the surface area per unit volume or unit weight increases, which means It enhances the swelling ability of rubber and promotes the compatibility between modifier (rubber powder) and asphalt. The influence of fine rubber powder on low temperature properties is more effective than that of coarse rubber powder, and the creep stiff...
