ABSTRACT
The development and study of the rheological and electrical properties of bitumen modified with carbon nanotubes is exposed. This modification transforms the bitumen into electrical semiconductor material, which opens a new range of possibilities of use to a material that, usually, acts as an electrical insulator.
As an example of these new applications, design and study of asphalt mixes made with carbon nanotubes modified binders conferring improved self-healing properties to the mixture by microwave absorption are presented.
Results showed in this paper have been obtained in the development of the MAMCE project, granted by the Spanish “Ministerio de Economía y Competitividad”, call “Innpacto 2011”.
