Crumb rubber modified bitumen (CRUMBit).

The main purpose of this research is to identify the barriers which inhibit currently the use of tyre-derived crumb rubber in Belgian asphalt roads and to develop different market-ready solutions that can be introduced to the road authorities.The main expected results for phase I of this research are the following: detection of possible toxicity and health issues when using crumb rubber as bitumen modification (e.g. measurement of the volatile organic compounds or VOCs) and comparison of the mechanical and rheological properties of crumb rubber modified bitumen (CRmB) with commercial polymer modified bitumen (PmB).
