Method for calculating surface energy matching index of specific surface area of asphalt mortar-aggregate
Disclosed is a method for calculating surface energy matching index of specific surface area of asphalt mortar-aggregate, including the following steps: determining surface energy parameter of aggregate by vapor adsorption method; determining surface energy parameter of filler by improved capillary rising method; determining specific surface area of asphalt mixture aggregate by specific surface area coefficient method; using an automatic specific surface area and pore analyzer to determine the specific surface area of the filler; calculating adhesive bond energy of the asphalt mixture and adhesive bond energy under liquid condition; calculating the surface energy matching index of asphalt mortar-aggregate. The beneficial effects of this disclosure include: the water stability of asphalt mixture is improved because the influence of the surface energy matching index of the specific surface area of asphalt mortar-aggregate is considered.
