  • Producing something useful out of waste materials that would otherwise be discarded is the ideal scenario when it comes to sustainable recycling.
  • Machines specifically designed to simulate the strains of a lifetime of passing vehicles were used to test different mixes of RCA, coarse tyre crumbs, and fine tyre crumbs.
  • Ultimately the researchers decided that 0.5 percent fine crumb rubber to 99.5 percent RCA was the sweet spot, maintaining the necessary strength whilst also keeping the two materials cohesive.
