Abstract: The present invention relates to a process for the preparation of an asphalt mix composition, said process comprising: (1) providing an asphalt composition and heating said composition to a temperature in the range of from 110 to 200° C.; (2) providing a granular material and heating said material to a temperature in the range of from 110 to 240° C.; (3) providing one or more thermosetting reactive compounds; (4) adding the one or more thermosetting reactive compounds provided in (3) to the asphalt composition obtained in (1) and homogenizing the mixture for a duration in the range of from 2 to 180 s; (5) adding the mixture obtained in (4) to the granular material obtained in (2) and homogenizing the slurry for a duration in the range of from 5 to 180 s. Further, the present invention relates to an asphalt mix composition obtained or obtainable by said process and its use.
