FOAMED BITUMEN RECYCLING

Foamed Bitumen Recycling is a proven solution for the long-term rehabilitation of pavements that have reached the end of their useful life, or need strengthening to accommodate increased loading.

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

Foamed Bitumen Recycling is quick to deliver and results in a strong and durable basecourse, with viscoelastic performance approaching that of asphalt. The process also eliminates the need for new aggregates and the end product can be trafficked almost immediately.

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

The technology is used extensively in maintenance, rehabilitation and new pavement construction.

Benefits

Foamed bitumen recycling produces a strong, durable and flexible pavement, with viscoelastic performance similar to asphalt.

Foamed bitumen is proven as an effective treatment for mitigation of pavement deterioration due to freezing and thawing.

Conserves diminishing aggregate resources.

Significantly reduces or eliminates excavation volumes.

Quick turn-around process minimises inconvenience to the public.

Can be trafficked almost immediately.

Reduced maintenance requirements and whole-of-life costs.

Significantly improved resistance to moisture.

No risk of shrinkage cracking.

Innovation

Hiway Stabilizers has been one of the pioneers in the use of Foamed Bitumen Recycling and has proven experience in successfully completing projects in high traffic and highly demanding conditions including motorways and airport runways.

Hiway Stabilizers have experienced construction teams for both in-situ foamed bitumen stabilising and recycling as well as ex-situ mobile plant mixed foamed bitumen product.

We have also led the development of Aggregate Modification technology in Australasia including the use of innovative stabilising agents.

DESIGN & PROJECT MANAGEMENT SERVICES

Hiway Stabilizers’ engineering team has extensive experience in pavement design and project management.

Our track record covers a variety of pavement types, including heavy duty pavements for port and airport applications, high level structural and modified highway pavements, and optimisation of design life for pavements on low volume roads.

We offer a range of consultancy services, from pavement investigation and materials classification, sampling and subgrade analysis, to bitumen ‘foamability’ testing and foamed bitumen mix design. We also have significant experience in determining the optimum pavement and mix design technologies to deliver the required pavement performance and optimise whole of life costs.
