New mix trial crushed into Brimbank roads


More recycled, crushed glass in asphalt could be used to construct roads throughout Brimbank under a new research trial project heralded as a first in Australia.

Brimbank City Council, in partnership with the Australian Road Research Board (ARRB) and Department of Transport (VicRoads), has secured $200,000 in funding from Sustainability Victoria for a new research trial project which could introduce more recycled crushed glass in hot mix asphalt for roads within the municipality.

Mayor of Brimbank, Cr Lucinda Congreve said the Research, Development and Demonstration grant will allow Council, in collaboration with the ARRB and VicRoads, to test, evaluate and potentially implement a new asphalt mix which uses a higher proportion of recycled glass.

The aim of the project is to:

  • improve road performance
  • increase durability (reduce lifecycle cost), and
  • lower the impact on the environment (less reliance on virgin sand, reduce waste, create value for waste materials)

“Although a small component of crushed glass has been used as a supplementary material for a number of years in Australia, this is the first time that a much higher concentration of glass content will be trialled.

“The new mix has the potential to become the new standard for road authorities to adopt as the composite material of choice for road constructions.

“Recovering a valuable resource such as glass and giving it a second life will also reduce the amount of material required to be landfilled, which is in line with Council’s efforts to find workable options for recyclables. We need a sustainable waste economy and local industry based on alternative and advanced waste and resource recovery,” said Cr Congreve.

The project will begin in late 2019 and is expected to be completed in mid-2021. It is one of nine in Victoria to receive a combined total of $1.6 million for development and research trials that make use of recycled glass, plastic, paper and e-waste.

The funding is part of the State Government’s $4.5 million Market Development for Recovered Resources Program which aims to increase consumer and business confidence in the quality of recycled content in products, support the growth of new or existing products, and keep valuable resources out of landfill.
