Abstract

An asphalt composition comprising 0.1 to 10.0 wt.-% based on the total weight of the composition of a thermosetting reactive compound selected from the group consisting of polymeric MDI, epoxy resins and melamine formaldehyde resins, wherein at least 18% by weight based on the total weight of the composition are particles with a sedimentation coefficient above 5000 Sved in a white spirit solvent.
