This report is about accelerate-aging tests which are simulating the heat aging(process) during mixing at an asphalt plant and the oxidativeaging (process) occuring in asphalt binders during service. The accelerate-hardening test methods were TFOT,RTFOT, and PAV. A new test method for the accelerateoxidatiVe aging using an oxygen filled oven at 60$B!n(J. From these test methods we can conclude that 1)TFOT which modified testing time, was the same hardening as during mixing at an asphalt plant, 2)PAV and the accelerate-oxidative aging using an oxygen filled oven at 60$B!n(J were similar as far as oxidative aging of asphalt in field.
