Recycled crushed concrete, crushed brick, glass fines, Reclaimed Asphalt Pavement (RAP) and crumbed rubber products now commonly supplement traditional virgin aggregate and sand extracted from quarries in pavement construction.
The business case
The business case for councils and industry to use local recycled content in pavement construction demonstrates competitiveness as a supplement to traditional quarry materials based on quality, price and availability.
VicRoads is a national leader in the use of recycled products in pavement construction and provide a range of specifications and technical documentation to support the use of accredited recycled products from accredited suppliers.

Research, development and demonstrations
|Research lead||Project overview||Project case study|
|Downer||Downer partnered with Hume City Council, Close the Loop and RED Group to construct a demonstration road using recycled soft plastics, glass and toner cartridge in asphalt.||Soft Plastics Paving the Way (PDF, 1.4MB)|
|Swinburne University of Technology||Swinburne University in partnership with Alex Fraser Group and VicRoads investigate the application of glass fines as a a) supplementary material with recycled crushed rock in cement treated bound pavement (road base) applications and b) as a rigidity reduction material when used in unbound crushed concrete/crushed rock (triple) blends.||Glass fines in cement treated pavement (PDF, 678kB)|
|Swinburne University of Technology||Swinburne University in partnership with VicRoads researched using recycled crushed glass and crushed brick as supplementary material in cement treated bound pavement applications. This research resulted in VicRoads updating their specifications.||Crushed Brick as a supplementary material in cement treated crushed concrete pavement applications >|
|Swinburne University of Technology||Swinburne University investigated the use of recycled crushed glass (5mm minus glass fines) as a supplementary material with recycled concrete aggregates in cement treated bound pavement applications. This project resulted in VicRoads updating their specifications.||Crushed Glass as a supplementary material in cement treated crushed concrete pavement applications >|
