New technologies to make rubber modification of asphalt are under development and testing. But political will is the real key to diverting old tyres from landfill - Kristina Smith reports. A new way to introduce end-of-life tyre rubber into asphalt mixes could be the key to diverting more tyres away from landfill, according to Dr Davide Lo Presti, principal research fellow at the Nottingham Transportation Engineering Centre (NTEC) at the University of Nottingham.
