Sulstar® DA
Innovations in road construction
We offer road asphalt manufacturers and mineral-asphalt mixing plants, Sulstar® DA – an additive to mineral-asphalt mixes lowering MMA manufacturing costs while simultaneously increasing their usability parameters. Sulstar® DA is an innovative thermoplastic MMA modifier, based on sulphur polymer Sulstar® with the addition of an anti-inhalation mineral medium. The manufacturing cost of Sulstar® DA is over 50% lower than the asphalt price, therefore by substituting 40% of the asphalt with Sulstarem® DA substantial savings are obtained and the road has increased usability parameters.
Advantages
Lowering of costs of the bituminous binder and road construction costs
Greater durability obtained by
- a layer with resistance to curling
- the elimination of occurrence of ice lenses
- the increase of resistance to rut formation
The Sulstar® DA technology can be successfully applied using standard road construction equipment, it is only necessary to adapt the way of monitoring the polymer dosing on WMB
The Sulstar® technology enables the utilization of wastes for the production of road subgrade layers saving full value aggregates
