Electrically conductive nanocomposite bituminous binders containing carbon nanotubes and multilayer graphene

In the modern literature, there are practically no data on electrical characteristics of bituminous binders modified with carbon nanotubes and graphene nanoplates, while they necessary for design development innovative asphalt pavement compositions sensitive to super-high-frequency microwave radiation. Contemporary multi-component systems that may contain polymers, rubbers, synthetic or natural resins, inorganic salts, even fragrances. As a result application modifying additives, bitumen acquires high performance characteristics. A special class modifiers micro- nano-sized electrically conductive fibers particles (steel wool, fibers, black, nanotubes, nanoplates), use which makes it possible ensure sensibility radiation implementation process healing cracks in an its subsequent regeneration. part study, authors developed original technique produce multilayer graphene. Modified concentration range from 0.2 6 11 wt. % multi-walled (MWCNT) nanoplates (MG), respectively were experimentally obtained. For first time, dependence specific volume conductivity bitumen-based nanocomposites nanostructured filler (MWCNT MG) was researched. The maximum values 4.76×10−4 S/cm 3.5×10−4 containing MWCNT MG, respectively. study determined fractions at percolation threshold MG. They amounted 0.22 2.18, formation contour occurs significantly lower concentrations compared
