Abstract: An asphalt composition comprising 0.1 to 10.0 wt.-% monomeric methylene diphenyl diisocyanate (MDI) based on the total weight of the composition, wherein the monomeric MDI is carbodiimide modified and wherein the weight percentage of 4,4′-MDI in the carbodiimide modified monomeric MDI is in the range of from 65 to 85% and the weight percentage of carbodiimide is in the range of from 15 to 35% in the carbodiimide modified monomeric MDI; 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.
