Iterfibra
Avoidance of bitumen drainage
Improved mechanical performance
They are pellets composed of cellulose, mineral and/or synthetic fibres that reinforce and thicken bitumen. Iterfibra products are used to stabilise bitumen in porous and semi-porous asphalt mixes and in Splittmastix Asphalts (SMA). By reinforcing and thickening bitumen, these products allow to obtain high-performance asphalt pavements with longer service life.
