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%

Main components

  • sulfur-bitumen binder
  • granite macadam
  • screenings
