Research Area: Recycling of ground tyre rubber as modifier in bituminous binders for road construction provides a high-value application of the recycled material. According to literature, up to 1250 waste tyres can be used for a simple 50 mm asphalt overlay of one lane per one kilometre.

The available body of knowledge shows that the use of crumb rubber modified (CRM) binder in both asphalt and sprayed seals can lead to improved field performance; specifically, durability, cracking and skid resistance, and reduced traffic noise. CRM asphalt binder could be engineered to achieve similar performance of polymer-modified binders, widely adopted in Australia. Besides performance, environmental impacts and life-cycle costs of road maintenance can also be reduced by using CRM.

The candidate will investigate and develop binder characterisation methods that (1) can be used to rank different CRM binder types, (2) can be applied to compare the performance of CRM binders directly to conventional polymer modified bitumens (PMB), (3) are representative of field performance, (4) can be used for both asphalt and spray seal binders, (5) are applicable to different manufacturing technologies of CRM binders, e.g. wet blends and no-agitation blends, (6) take into account possible additives (i.e. extender oils or small percentage of other polymers) and base bitumen requirements, (7) incorporate and enhance current Australian bitumen standards, which are mainly based on empirical testing of physical properties of the binder.
