【 摘 要 】

In order to reduce the pavement wear caused by cracks which made by frost heave or temperature stress, the rubber powder or carbon black had been added to the asphalt roadbed with the as-prepared deicer agent, and the properties of the modified asphalt were evaluated by through penetration, softening point, ductility and Marshall test. The results showed that with the increase of the content of rubber powder (carbon black), the penetration and ductility of the asphalt decreased, and the softening point decreased slightly. When the content of rubber powder and carbon black was 10%, the modified effect of asphalt was the best. When the as-prepared deicer agent and rubber powder (carbon black) are added into the asphalt, the asphalt has some antiseptic and antifreeze properties, and the stability and flow value of the modified asphalt mixture increase, and the wear resistance of the asphalt pavement is increased.
