Bitumen Penetration Grade
EN Standard – Bitumen 50/70
Bitumen 50/70 is a high quality bitumen produced through the most modern industrial processes and appropriate crude oils. It has an optimum viscosity in the range of temperatures for mixing and laying operations, that guarantees an easy workability even for high stress conditions.
The product meets the European standard EN 12591 and achieves the maximum level of hardening resistance.
Uses
Bitumen 50/70, thanks to its very high performance in terms of resistance to aging, plasticity and behaviour at low temperatures, is employed to produce bituminous mixes constituting flexible structure for the paving of roadways, runways,pavement, track race and landing platform.
