MODBIT HiMA 45/80-80

The high modifier content results in the micro-structure of the asphalt dominated by a polymer phase. As a consequence, the product is characterised by enhanced functional parameters, while the application of a finished mineral-bitumen mixture is not hindered.

Polymer highly modified bitumen (types 25/55-80, 45/80-80, and 65/105-80) is applied in the construction and maintenance of roads, airports, and other hardened surfaces. The recommended use of this type of binder includes in particular mineral-bitumen mixtures in heavy-duty ‘long-lasting’ structural layers of a road pavement, where high resistance to ageing, resistance to fatigue and low-temperature cracking, and resistance to permanent deformation are required. It complies with PN-EN 14023:2011/Ap1:2014-04.
