探究了生物沥青的复数剪切模量、相位角、车辙因子和粘度随着不同温度、不同生物质重油掺量的变化而变化的情况。分析了根据粘温曲线确定生物沥青的拌合与压实温度存在的问题。研究表明，生物沥青的高温性能随着温度的增加及生物质重油掺量的增加而降低；在温度不大于135℃的范围内，随着生物质重油掺量的增加，生物沥青的粘度逐渐降低；生物沥青存在一定的老化现象；根据粘温曲线确定生物沥青拌合与压实温度的方法的适用性有待进一步研究。

The variations of complex shear modulus,phase angle ,rutting factor and viscosity under different temperatures and different contents of bio-oil were investigated.Some problems on the ascertai-ning of mixing and compaction temperature on bio-binder based on the viscosity-temperature curve were discussed.This research showed that the high temperature performances of bio-binder decreased with the increase of temperature and content of bio-oil if the testing temperature was below 135 ℃.There is some aging on the bio-binder if heated too high,and the method of determining the mixing and compaction tem-perature on bio-binder has to be studied in the future.
