Physical properties of SK-90 and Sasobit modified asphalt binder.

Asphalt binders	25°C penetration (0.1 mm)	15°C ductility (cm)	Softening point (°C)	60°C dynamic viscosity (Pa·s)	After RTFOT
					Mass loss (%)	Penetration ratio (%)	10°C ductility (cm)
SK-90	79	＞100	52.8	141.2	−0.113	61.3	10.4
Sasobit-modified asphalt binder	54	＞100	75.9	953.7	0.198	58.4	5.2
