摘要

This paper presents some findings from the recently completed research project on "Rubberised Asphalt Testing to UK Standards", funded by WRAP (Waste & Resources Action Programme). One of the aims from this study was to provide information to potential users of rubberised binder on the properties that can be expected from various sources/types of crumb rubber available in the UK, when blended with typical UK bitumens, specifically without using any additive. It was found that the selected three best blends satisfied target requirements for ageing index, softening point and viscosity. In addition, the blends exhibited improvements in short and long term ageing, cohesion characteristics, Fraass breaking point, service temperature range and flash point values compared to typical penetration grade bitumen, and satisfactory residual properties after storage stability testing.
