高速公路沥青路面结构与材料设计发展的调研

Investigation on Development of Structure & Material Design for Asphalt Pavements of Freeway

沥青路面高速公路在我国发展迅速。不少地区在实践中积聚了失败与成功的经验。通过走访调研,收集整理了上海、江苏、山东、湖北和安徽等地的沥青路面结构设计资料以及路况。根据沥青面层使用材料的不同,把我国沥青路面发展划分为三个阶段。分析指出我国沥青路面的发展主要围绕新材料的开发应用展开,材料性能设计方法的研究明显投入不足。亟待探讨基于路用性能的沥青混合料性能设计方法。

Asphalt pavements freeway in our country have experienced great development.Failure and success experience was accumu- lated from practice in different area.Through investigation and visitation,the design data and service conditions of asphalt pave- ments,in Shanghai,Jiangsu,Shandong,Hubei and Anhui province,were collected and processed.According to the paving mixing material types used in the surface layer,the development stages of asphalt pavement in our country can be divided into three different phases.Therefore,this paper pointed out that development of asphalt pavement in our country is in accordance with the research and application of new material,and the investment on asphalt material performance design method is obviously not enough.And then, mixing design method based on pavements performance for asphalt mixtures is urgently to be developed.
