Foamed Bitumen Stabilisation

Foamed Bitumen is becoming a solution of choice for the construction of heavily trafficked pavements. It is a highly cost-effective alternative to asphalt and traditional remediation methods and is particularly useful in level-constrained settings where a significant overlay is not feasible.

Foamed Bitumen is quick to deliver and results in a strong and durable basecourse, with viscoelastic performance approaching that of asphalt. The process can also eliminate the need for new aggregates and the end-product can be trafficked almost immediately, making it perfect for environments where works are carried out adjacent to active lanes.

The versatility and successful track record of Foamed Bitumen in a wide range of extreme conditions has led it to be used extensively in Australia, South Africa, the UK, North America, the Middle East and Europe.

Foamed Bitumen is a highly cost-effect alternative to asphalt and traditional remediation methods.


Hiway Group has been the leading industry pioneer in the use of foamed bitumen stabilisation and has proven experience in successfully completing projects in high traffic and highly demanding conditions including motorways and airport runways.
