Paving the way with rubber

Bayside Council is set to test a new modified asphalt mix on a local road as part of a project coordinated by the Southern Sydney Regional Organisation of Councils (SSROC) that could see old tyres used for roads.

Paving The Way With Rubber is a significant project investigating the use of crumbed rubber from ‘end of life’ tyres to make a modified road asphalt mix.

“It is exciting to see Bayside Council participating in a trial that could see old tyres recycled into material to build local and state roads,” Mayor Dr Christina Curry said.

“This is a great example of how Bayside Council is actively working with other councils to find sustainable solutions to modern day problems.”

Paving The Way With Rubber is examining the performance of crumbed rubber asphalt from an environmental and road performance perspective and results from the Bayside trial could see crumbed rubber used on local and state roads.

Bayside Council collects 1200 tyres per annum whilst metropolitan Sydney disposes of around 64,000 truck and 34,000 car tyres per year.

Preliminary findings show the following positive results:

  • Pavement fatigue resistance is enhanced by +20 to 50%
  • Rut resistance is enhanced by +20 to 100% depending on content of crushed rubber mix
  • Trials indicate extended local road life by 40-50%
  • Recycled end-of-life tyres in roads can save 75% of CO2 emissions compared to sending them to landfill.

Bayside Council is an active member of Southern Sydney Regional Organisation of Councils (SSROC) an association of 11 councils spanning Sydney’s southern, eastern, central and inner west suburbs.
