Abstract:
Disclosed is a design reference value quantification method for a modifier dosage of modified asphalt. A curve of unsaturation degree of the modified asphalt as a function of the modifier dosage is plotted, in which the unsaturation degree of a series of modified asphalts is determined by potentiometric titration; further, an inflection point of the unsaturation degree of the modified asphalt as a function of the modifier dosage in the asphalt is obtained by data fitting and analysis, and a reference value of the dosage of the modifier added in the process design of the modified asphalt is established.
