Research On Application Of The Modified Asphalt On Highway Pavement In The Region Of Beijing

This paper briefly introduces the history of development of the modified asphalt in China and abroad and its classification as well. Through numders of analysis on the formation mechanism of modified ashalts used in Beijing area,also by conducting conventional test,non-conventional test, special test in laboratory and application on highway paveraent,this research studies the effect of different denaturing agents in modified asphalt.lt makes also before-after studies, comparing different denaturing agents, comparing effect on different basic materials after modification and results in the adaptability of different modified asphalt under different climate and traffic conditions, thus provides a good technical support for the application of modified asphalt on the highway asphalt pavement.
