UNIBIT 35/50
Menu
Product information
This bitumen is applied in road building for producing:
- asphalt concrete (BA) for building base course layers and a binding surface,
- asphalt concrete of a high stiffness module (BA WMS),
- stone mastix asphalt (SMA),
- cast bitumen.
The use of this bitumen in producing asphalt concrete provides a building material that features high resistance to permanent deformations and maintains resistance to low-temperature cracking. The special bitumen UNIBIT 35/50 proves itself in road structures located in areas with a high annual amplitude of temperatures and exposed to very heavy traffic load.
