原始语种摘要: Abstract(#br)This study aims at investigating the composite modification effect of castor beans-based bio-asphalt and European rock asphalt on the properties of asphalt binders and optimizing the blending ratio of composite modified asphalt for specific properties by D-optimal mixture design (DMD). Penetration, softening point, ductility, rotary viscosity and dynamic shear rheometer (DSR) tests results revealed the addition of rock asphalt could compensate the adverse effect of bio-asphalt on the high-temperature performance of asphalt, and bio-asphalt could promote the swelling of rock asphalt by increasing complex modulus ( G* ) and decreased phase angle ( δ ). Fourier transform infrared spectroscopy (FTIR) results indicated that there no true chemical reaction occurred between...
