Sulfur-extended asphalt concrete – new-generation roads composite material
It is used for road surfacing of settlements and highways.
Advantages in comparison with asphalt concrete based on bitumen binder
- increase in compressive strength at 50ºС by 1.5 – 2 times
- increase in rutting resistance
- increased corrosion resistance to deicing agents
- reduced energy consumption due to temperature conditions optimisation
- cost reduction by 8 – 10%
