Abstract
Disclosed is a method for determining a mixing temperature of an asphalt mixture which includes the following steps: S, obtaining a test result of surface energy of hot-melt asphalt; S, obtaining, according to a calculation formula for total adhesion work and in combination with the test result of the surface energy of the hot-melt asphalt, total adhesion work of an asphalt and aggregate interface at different mixing temperatures; S, determining a temperature range corresponding to peak values of the total adhesion work of the asphalt and aggregate interface; and S, calculating a median value of the temperature range determined in S, so as to determine an optimum mixing temperature of the asphalt mixture.
