  • Publication number: 20200308410
    Abstract: Nano-reinforced materials hold the potential to redefine traditional materials both in terms of performance and potential applications. Dispersing carbon nanofibers (“CNF”) in Hot Mix Asphalt mixtures creates a piezoresistive effect and classifies the new mixture as a “smart material.” The current invention uses the electromechanical capabilities of carbon fibers to sense its own strain by way of electrical resistivity to develop a Self-sensing Piezoresistive Hot Mix Asphalt.
    Type: Application
