Bitumen is designed for all hot-mix bituminous layers of road surfaces. In particular, the binders are used for binder layers and substructures made from mineral and bitumen mixtures of the bitumen concrete (AC) type in the KR3 – KR4 and KR5 – KR7 traffic categories. Bitumen can be used as a binder for the production of poured bitumen.
Complies with the PN-EN 12591:2010 standard
