摘要：

This study conducted a laboratory investigation to assess the effects and rejuvenation mechanism of wood tar-based rejuvenator (WTR) on the properties of aged 70# base asphalt and styrene-butadiene-styrene (SBS) modified asphalt, using a commercial rejuvenator RA-102 as a reference. The conventional physical properties (penetration, ductility, softening point, and viscosity), high and low temperature rheological properties, composition, chemical characteristics, and microscopic characteristics of asphalt under different aging states were tested...
