Abstract
This invention relates to the modification of bitumen by polymeric materials used particularly for the preparation of asphalt mixtures with enhanced mechanical properties, wherein the polymeric materials are selected from additives capable of forming a supramolecular assembly. The modified bitumen may be used for the fabrication of asphalts mixtures with mineral aggregates used in construction or maintenance of sidewalks, roads, highways, parking lots or airport runaways and service roads and any other rolling surfaces.
