The bitumen we use in our roads and buildings is refined from carefully selected crude oils. A variety of different refining methods produce different kinds of bitumen and allow the manufacturer to produce specific characteristics in the bitumen. Producers often blend multiple crude oils together to produce consistent, high-quality bitumen that meets precise engineering specifications.

  • Hard bitumen for use in road construction.
  • Cutback bitumen – a blend of bitumens with solvents such as kerosene.
  • Emulsions – stable solutions of bitumen in water.
  • Polymer-modified bitumens – mixtures of special bitumens with polymers such as thermoplastics or elastomers.
