Test Study On The Performance Of The Composite Recycled And Modified Asphalt

Asphalt highways and urban roads presently use is mainly petroleum asphalt, petroleum asphalt is extracted from oil. According to the relevant studies have shown that the world’s oil reserves are available for human use for only about 100 years, and this petroleum substance is non-renewable energy, it will pollute the environment after abandonment, so whether road asphalt can be recycled and used effectively is particularly important. This paper mainly through laboratory simulation of asphalt aging and modify for regeneration and aging asphalt, analyze asphalt’s major indicator’s change rule in the regeneration process of modification. By observations of electron micrographs component test, analyze and make a contrast with among modified asphalt in the regeneration process of the composite and component index changes and changes in electron micrographs. Experimental study on aging asphalt modified by regeneration and experimental research and analysis as well as an experimental research about aging mechanism modified asphalt compound in a different order of regeneration. Comprehensive analysis of various data based on the proposed mechanism of aging complex regeneration modified asphalt technology enriches the asphalt pavement recycling technology. Asphalt content increases in the aging process and decreases in the other three components. In the process of compound regenerative modification, changes in the components of the composite regenerated asphalt modification process is in line with changes in each index. Regeneration through experimental data contrast analysis of modified integrated technology can be reused for many times, make the aging asphalt recycled asphalt performance comprehensive improvement, the aging of asphalt mixture recycling has a certain guiding role.
