文摘
Modified asphalt binders were prepared by adding conductive materials, graphite and carbon fiber. The rotation thin film oven test (RTFOT) and pressure age vessel test (PAV) were conducted to simulate the binder aging in the field. Rheological properties of graphite and carbon fiber modified asphalt binder were investigated by the empirically rheological properties (penetration and softening point) and the dynamic shear rheometer (DSR) test. Results show that physical properties of asphalt binder change with conductive material mixed. DSR tests present that the values of complex modulus increase while phase angles decrease under a proper amount of graphite and carbon fiber. Rutting parameters point out that graphite can improve the rutting resistance of asphalts. Rheological parameters can be used to assess aging.
