Influence of Furfural Extracted Oil on Basic Properties of Asphalt
The performance of bitumen mainly depends on the chemical composition of bitumen, in order to study the influence of asphalt component ratio on performance, furfural extraction oil was used to blend and modify bitumen, and modified bitumen with different component proportions was prepared, and three-index test and four-component test were carried out on the modified asphalt. The effects of furfural extraction oil content on the proportion of asphalt components and the effects of asphalt component changes on penetration degree and softening point were studied. The results showed that with the increase of furfural extraction oil content, the bitumen penetration degree gradually increased, the softening point gradually decreased, the content of saturated and aromatic components gradually increased, the content of asphaltenes and gums gradually reduced. According to the correlation between the changes of the three components of asphalt and the penetration degree and softening point of asphalt, it was concluded that the penetration degree of bitumen had a negative correlation with asphaltene,negatively correlated with saturation and aromatic components, and had a positive correlation between asphalt softening point and asphaltene, and negatively correlated with saturation, aromatic and gum.
