Bitumen 35/50

Bitumen 35/50 is a high quality bitumen with the most modern industrial processes and using appropriate crude oils.

Description

1.Description:
Bitumen 35/50 is a high quality bitumen with the most modern industrial processes and using appropriate crude oils. It has an optimum viscosity in the range of temperatures for mixing and laying that guarantees easy workability of the products, even for high stress conditions.
The product meets the European standard EN 12591 and achieves the maximum level of hardening resistance.

2. Uses
Bitumen 35/50, 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.
