高黏度改性沥青在上海公路中的应用回顾及其长寿命探讨

Review of the Application and Discussion on the Long-life Potential of High Viscosity Modified Asphalt in Shanghai Highway

“双碳”政策的推行,加速了我国对长寿命道路技术的需求,故长寿命路面结构与材料一体化研究有着重要意义。在回顾上海地区实体工程卢浦大桥、东海大桥、浦东新区排水路面的基础上,分析了高黏度改性沥青对路面服役性能及耐久性的改善作用,并结合长寿命道路在国内外的发展,讨论了不同地区对长寿命路面的定义及设计差异,论证了高黏度改性沥青在长寿命道路建设中的可行性及优势。

The implementation of carbon peaking and carbon neutrality has accelerated the demand for long-life pavement in China,and the research on integration of the structure and material of long-life pavement is of great importance.Based on the review of physical projects(Lupu Bridge,Donghai Bridge and drainage pavement in Pudong New Area)in Shanghai,this article analyzed the improvement of high-viscosity modified asphalt on pavement performance and durability.And combined with the development of long-life pavement over the world,discussed the definition and design differences of long-life pavement in different regions,and demonstrated the feasibility and advantages of high-viscosity modified asphalt in the construction of long-life pavement.
