Recycled crushed glass as road-base

Although the use of recycled glass in the construction industry has become a more familiar sight in recent years in Australia, it wasn't until 2021 that we introduced it into South Australia's infrastructure construction sector.

Back then, our team on the R2P Project worked with supplier, ResourceCo, and our customer, the Department for Infrastructure and Transport (DIT), to trial a PM2/20 road-base product containing 5% recycled glass on an arterial road project. The trial was a resounding success.

Leap ahead to mid 2022 and our team on the Ovingham Level Crossing Removal project in Adelaide upped the ante, this time using 10% recycled crushed glass within 660 tonnes of road-base. Again, this was the first time this level of recycled glass was used on a DIT project.

The result was the diversion of 66 tonnes of municipal glass waste from land fill, the equivalent of 132,000 empty wine bottles.

At the heart of these initiatives is our "Creative Construction" ethos, our focus on the circular economy, and the collaboration and trust we foster between our design, construction and customer teams.
