Performance of Nano-TiO2/Graphene Composite Modified Asphalt
AbstractIn this research, nano-TiO2 and graphene composite were added to asphalt to enhance the performance of asphalt by synergistically improving the dispersion of each other. The physical properties of the modified asphalt were assessed using penetration, softening point, and ductility tests, and...

| description | AbstractIn this research, nano-TiO2 and graphene composite were added to asphalt to enhance the performance of asphalt by synergistically improving the dispersion of each other. The physical properties of the modified asphalt were assessed using penetration, softening point, and ductility tests, and the rheological performance of the asphalt was studied using dynamic shear rheometric (DSR) and bending beam rheometric (BBR) tests. In addition, scanning electron microscopy (SEM), Fourier-transform infrared (FTIR) spectroscopy, and nanoparticle size analyzer (DLS) were used for microscopic analysis of asphalt. The results demonstrated that the incorporation of nano-TiO2 and graphene in asphalt could improve the high-temperature properties and the aging resistance of base asphalt. In terms of low temperature performance, the composite of nano-TiO2 with graphene improves the negative effects of the single addition of nano-TiO2 or graphene. Microscopic analysis indicated that the dispersion of the nano-TiO2 and graphene in the asphalt synergistically was improved significantly. The optimum amount of 1% nano-TiO2 and 0.04% graphene is recommended for the composite. This study provides a basis for the diversified application and development of nanomaterial modified asphalt in the future. |
