生物质树脂改性沥青技术性能研究

Study on the performance of the asphalt modified with biomass derived resins

通过动态剪切流变试验(DSR)和弯曲梁流变试验(BBR)研究生物质树脂改性沥青技术性能,采用复数模量、相位角、车辙因子、疲劳因子、蠕变劲度和蠕变速率六个表征沥青性能。研究表明,生物质树脂能改善沥青胶结料技术性能,生物质树脂最佳掺量为30%。

The performance of the asphalt modified with biomass derived resins is studied by dynamic shear rheometer test（ DSR） and bending beam rheometer test（ BBR）,and the asphalt performance is represented by the following six characterizations： complex modulus,phase angle,rutting factor,the factors of fatigue,creep stiffness and creep rate. The research shows that the biomass derived resins can improve the performance of asphalt binder,and the best content of biomass derived resins is 30%.
