FURFURAL RESIDUE/ILLEGAL COOKING OIL MODIFIED ASPHALT AND PREPARATION METHOD THEREFOR

WIPO Patent Application WO/2023/092776

A1

Provided are a furfural residue/illegal cooking oil modified asphalt and a preparation method therefor, which belong to the technical field of asphalt modification. The modified asphalt is composed of a furfural residue/illegal cooking oil composite modifier and asphalt. The preparation method comprises: 1. drying a furfural residue, and sieving same with a 80-mesh mesh sieve; 2. mixing the furfural residue and an illegal cooking oil, shearing and filtering same to obtain a furfural residue/illegal cooking oil composite modifier; and 3. pouring the furfural residue/illegal cooking oil composite modifier into asphalt, and shearing and cooling same to obtain a furfural residue/illegal cooking oil modified asphalt. The furfural residue can be uniformly dispersed in a system of the illegal cooking oil and asphalt, and the compatibility is relatively good. The technical problems of a large amount of fossil resources being consumed, and petroleum asphalt harming the environment and the health of constructors are solved.
