Modified Asphalt Materials in Highway Engineering

Asphalt is widely used in engineering,but relying solely on the nature of the asphalt itself,it is difficult to meet a wide range of road works on asphalt requirements.Therefore,in order to meet project requirements,the need to improve the performance of the asphalt.The application of modified asphalt can improve asphalt pavement deformation resistance,can enhance the anti-rutting performance of asphalt pavement to improve the elastic properties of asphalt,asphalt can enhance the resistance to low temperature and fatigue cracking,asphalt and aggregate to improve the adhesion of improve the ability of anti-aging asphalt to extend the service life of asphalt pavement.This article discusses the performance of modified asphalt and production processes,for highway construction quality control of asphalt pavement application infrastructure.
