Highly modified bitumen Modbit Hima

Highly modified polymer bitumen is a new development in technologically advanced bitumen. The level of SBS-type polymer modification is more than double that of modified bitumen, which is commonly used in the wearing conditions of road surfaces. The high modifier content translates into a bitumen microstructure with a predominantly polymeric phase, thanks to which the product has enhanced functional parameters while at the same time not hindering the incorporation of the finished bitumen-asphalt mixture.

Highly modified polymer bitumen (types 25/55-80, 45/80-80 and 65/105-80) is used for construction and maintenance of roads, airports and other paved surfaces. Recommended applications for this type of binder are in particular mineral and bitumen mixtures in the construction layers of very durable – “long-life” – road surfaces, where very high ageing resistance, resistance to fatigue and low-temperature cracking and resistance to permanent deformation are required.
