Enhanced binder interface at 750°C
Calcined at 750°C, the coal gangue particles become finer and rougher, with higher adhesion energy to asphalt, improving high-temperature deformation resistance and low-temperature cracking resistance of mastic.

At 750°C calcination, CGAM shows superior high-temperature deformation resistance and low-temperature flexural creep ability
Calcination causes crystal phase transition and increased alkali mineral proportion
Activated CG has smaller particle size and rougher surface
