改性沥青技术在高等级道路中的应用研究

Application of Modified Asphalt Technology on HIGHWAY

随着我国公路交通的迅速发展,通车总里程逐年增加,而沥青路面占据了较高的比例,相应带来对高等级公路沥青路面材料的要求越来越高,改性沥青以其优良的技术性能和经济性能得到了广泛的应用。本文通过对改性沥青在道路中的应用介绍,并对目前改性沥青使用中的一些误区进行分析,可供道路专业人员在道路设计及维修养护方案的选择上借鉴。

With the rapid growth of highway traffic, the total mileage increased year by year, while the asphalt pavement occupies a higher proportion, corresponding to bring the materials requirements for high-level asphalt pavement increasingly high, and the modified asphalt with its excellent technical and economic performance has been widely used. Base on the application introduction of modified asphalt in the roads, and the analysis of misunderstanding in current modified asphalt usage, this article can be used for road professionals as reference of road design and maintenance of the conservation programs.
