Mit nanokomposit modifizierter asphaltbinder und dessen herstellung

Abstract

The present invention relates to modified binders comprising nanocomposite based on clay and fumed silica, wherein said modified binder is in particular one which is suitable as an admixture for asphalt binders, in particular bitumen. In a further aspect, a method for producing said modified binder is provided, wherein the nanocomposite based on clay and fumed silica is produced by hydrothermal synthesis. In addition, compositions comprising the modified binders according to the invention, such as asphalt, are provided accordingly, as well as the use of these modified binders to improve the UV resistance, to increase the strength and/or to improve the crack resistance of asphalt.
