摘要
采用红外分析,核磁共振等高等仪器对塔河沥青进行了分子结构的表征,对塔河沥青的四组分进行了分析,并采用布朗-拉德纳法计算了老化前后塔河沥青四组分的芳香度。结果表明:塔河沥青具有低温延度低,抗老化性能差的特点。
The molecular structure of Tahe asphalt was determined by FT-IR and 1H-NMR.And chemical four constituents were also analyzed for Tahe asphalt,while the aromaticity of four constituents with and without aging was calculated by Brown-Ladner＇s method.The result indicated that the ductility for low temperature of Tahe asphalt was low and anti-aging properties were poor.
