摘要
用毛细管粘变计测定了35个道路沥青在60—160℃的粘度。结果表明,由不同油源和不同加工方法得到的沥青具有不同的粘度和粘温关系。大多数道路沥青在60—160℃的粘温关系可依下式呈线性:1g
The viscosities of 35 road asphalts produced from different crudes by diff-erent processing methods were measured with the capillary viscosimeter.Theresults showed that the viscosity and viscosity-temperature dependency ofthe asphalt varies with crude source and processing method.The viscosity-temperature dependency of most road asphalts in the range of 60—160℃ canbe described by the expressionIgIgη=m(?)gT+b
