| Abstract: | We modified asphalt with a high carbon content mineral in this paper.The properties of the mineral were characterized with energy dispersive spectrometer (EDS), fourier transform infra-red spectrum (FT-IR) and element analyzer.The properties of the modified asphalt were tested.The modification mechanism of the modified asphalt was analyzed with FT-IR. Moreover, the properties and penetration index of the modified asphalt were studied and evaluated, respectively.The results showed that the mineral markedly improved the properties and viscosity-temperature susceptibility.The modified asphalt is mainly physical modification.Therefore, the modified asphalt could be used as an excellent binder for pavement. |
