Results

• Either AC or furan resin decreased the penetration value and increased the softening point

• Classical bitumen’s stifness was increased with two modifiers

• Both of the modifiers decreased the temperature susceptibility of classical bitumen

• Flash point test results inicated that there is no porblem for using modified bitumens at construction site

• Aging characteristics were developed with modification• Stability of modified mixtures increased but flow values

decreased• Rutting resistance of pavement developed with

modification
