Research on Short-term Aging of Lignin Modified Asphalt
In order to study the micro-aging mechanism of lignin-modified asphalt, different asphalt samples were prepared with lignin content of 0% and 12% by mass. The conventional asphalt index test and high-temperature dynamic shear rheological test were used to analyze the different asphalt samples. The change law of the performance of modified lignin modified asphalt with thermal oxygen aging time. The results show that adding appropriate amount of lignin to each asphalt will increase the penetration and ductility of the base asphalt, reduce the softening point, and significantly improve the high-temperature stability; comparative analysis before and after DSR aging, the complex shear modulus G* increases and The decrease of phase angle δ indicates that lignin can improve the high-temperature rheological properties of asphalt.
