改性沥青材料在公路工程中的应用

Modified Asphalt Materials in Highway Engineering

沥青已在公路施工中得到广泛使用,但单纯依靠沥青自身性质很难满足道路工程对沥青的多方面要求。因此,为满足工程要求,需要对沥青性能加以改善。改性沥青的应用可以改善沥青路面的抗变形能力,也可以增强沥青路面的抗车辙性能及弹性性能,增强沥青的抗低温和抗疲劳开裂能力,改善沥青与集料的粘附性,延长沥青路面的使用寿命。分析探讨了改性沥青的性能和生产工艺,为公路工程沥青路面的质量控制提供应用基础。

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.
