Influence of chemical catalysts and selected additives on behavior of crumb rubber modified bitumen
Original language description
Since several years research in the field of crumb rubber modified bitumen (CRMB) is again an important area of interest. This fact is driven by restrictions for land-filling of old tires and their energetic use as a solid fuel e.g. in cement production.At the same time some experts expect that the use of higher content of crumb rubber in bitumen can further decrease the noise reducing potential if used in suitable acoustic asphalt mixes. Last but not least using crumb rubber as a modifier creates on the market binder which would fill the application gap between distilled bitumen and PMBs. Within the research done at Czech Technical University in Prague different types of micro-pulverized rubber has been used together with chemical catalysts suitablefor temporary devulcanization of the rubber. Further for improving the homogeneity and storage stability of the CRMB additional additives have been tested and their effects compared. For the bitumen samples traditional as well as performa
