Road bitumen 20/30
General information
This road bitumen is designated for producing all bituminous layers of road pavements in "hot" technology and primarily for the production of asphalt concrete of a high stiffness module (BA WMS), which is applied as a base course layer and a binding road pavement. Bitumen may be utilized as the base for producing cast bitumen.
It complies with PN-EN 12591:2010 standard.
