Project Case Study Timeline

These project case studies progress the technical development of MatrixMaterials, including the incorporation of angular quarry scalps and ‘weak’ aggregates such as coal wash reject.

Select projects exemplify MatrixMaterials’ adaptable technology, which in challenging conditions, has resulted in highly successful outcomes.

This is a snapshot of the technology’s application – the material has also been used for “capping material” in the construction of rail formations, and for airport hardstands with excellent outcomes.

More than 2 million tonnes of MatrixMaterials has been used successfully in the construction and maintenance of NSW infrastructure since 2002.

May to September 2016 - car storage hardstand, Redalls Road, Kembla Grange



266,000m2 hardstand for parking imported cars – the size of 38 football fields. A novel pavement design was used, saving the client, a major Australian car transport company, more than $2 million. Utlised unbound MatrixBase incorporating coal wash reject.

July 2016 - Dwyer Road, Leppington

Camden delivery

This project for Camden Council was a rehabilitation overlay for a low traffic volume residential road.

March 2016 - Vista Park, Wongawilli

Wongawilli completeThis project involved laying roads for Wollonging Council, as part of a new subdivision.

April 2013 - West Cliff Colliery

West Cliff cores
West Cliff traffic
Weak aggregates, coal wash reject, were subjected to heavy traffic and high loads in an unsealed internal mine road in this project.

April 2012 - Back Cullen Road, Portland

Lithgow constructionLithgow completed
This project for Lithgow City Council progressed understanding of weak aggregates in low traffic roads.

January to March 2009 - Bangalow Rd, Lismore

Lismore post-construction flood

Lismore complete
With repeated flooding over the road, this project indicated the performance capabilities of low permeability road base.

2002 to 2006 - Bucketts Way, cross-regional

Bucketts Way sign    Bucketts Way compaction
This project for the Australian Federal Government used angular scalps and showed that shape and size are not important factors in road base performance.

2004 - Mitchell Hwy, Vittoria

Vittoria compactionVittoria site inspetion 9 yrs later
Used conventional road base aggregate with added fines to show improved workability and compaction.

2003 - Mitchell Hwy, Ammerdown

Ammerdown compaction
Ammerdown complete - 10 yrs later
Used conventional road base aggregate with added fines to show improved workability and compaction.
