Performance behavior of bitumen modified by new generation of activated rubber powder
Original language description
This paper presents results of more than 5 year innovation development which is related to improving modification of bitumen by crumb rubber. The traditional crumb rubber coming from old tires is further pulverized and activated using high-speed disintegration process during which fractal rubber particles of size < 0.8 mm are gained and used as a modifier together with suitable additives in bitumen. A performance improved and storage stable product is finally generated. Such modified bitumen in several alternatives was tested using traditional empirical tests as well as performance-based (functional) characteristics focusing mainly on the deformation behavior. Technically most efficient rubber modified binders where then used in some asphalt mixtures to verify their added value to the performance of the asphalt. Selected results are presented and discussed in the paper focusing on bituminous binders containing 10-15 % of the activated rubber powder.
