| Hot asphalt recycling technology has been more and more applications to the various levels of road repair and overhaul. Known for their, the old asphalt mixture recycling can not only save resources but also reduce environmental pollution caused by waste. However, there are targeted for the reclaimed mix asphalt mixture on. This thesis conducted at the Modified Asphalt Hot Mixed recycling technology research.Main contents includes the following parts:1, SBS modified asphalt and asphalt indoor thermal oxidative aging of long-term study; 2, conduct SBS modified and asphalt which after aging agents to infrared spectrum; 3, composed of recycled asphalt mixture design and Performance Studies.Through the above analysis of the contents of this thesis, the following conclusions:1, through the asphalt on the different long-term thermal aging, come to the aging of the aging prediction equation can be used to simulate the nonlinear and rate-based aging parameters of aging performance evaluation method of the four kinds of anti-aging properties of asphalt evaluation; 2 different aging time on the asphalt and modifier of IR test, using carbonyl index and sulfoxide-based index of the asphalt and modifier to evaluate the degree of aging, SBS modifier derived anti-aging properties than asphalt and modified asphalt; 3, through the mixture of recycled asphalt for composition design of mixed materials with different rates of old and new asphalt recycling agent type and dose on the regeneration of modified asphalt mixtures properties, and of recycled asphalt pavement performance proposed indicators;...
