永久性沥青路面研究综述

Summary on Perpetual Asphalt Pavement Research

永久性沥青路面的设计理念代表了国外高等公路路面结构、材料选择和设计新趋势,具有一定的合理性。本文评述了永久性沥青路面的概念及结构特点,总结了目前基于力学的永久性沥青路面结构设计方法,介绍了永久性沥青路面各结构层材料设计的特点,以及永久性沥青路面的施工、养护维修特色和寿命经济分析。揭示了永久性沥青路面具有区别于传统路面的结构特性,以及具有优良的路用性能。建议修建高等级公路时能借鉴国外永久性沥青路面实践经验,提出基于永久性沥青路面设计理念的设计方法和施工工艺,以提高我国高等级公路的经济效益和社会效益。最后提出了基于我国的特点,需要进一步开展的研究工作。

Design concept of perpetual asphalt pavement represents the new tendency of pavement structure and material design abroad. The concept and character of perpetual asphalt pavement structures were appraised. The design ways of pavement structure, character of material design, character of construction and maintenance on perpetual asphalt pavement were explained. At the same time, the economic analysis was done. The structure characteristics of perpetual pavement were posted to be distinguished from that of traditional pavement structures, and to have good performance. Thus to borrow ideas of perpetual pavement from foreign experiences in high-grade highway construction is proposed and a design method and construction technology is put forward based on perpetual pavement design concept, which could enhance the economic efficiency and the social benefit of high-grade highway in China. At last the works should be done is shown based on Chinese characteristics in future.
