摘要
目前沥青路面使用一定年限后普遍出现一些问题 ,解决的途径只有从结构、材料、工艺 3方面考虑 .笔者在调查大量相关资料的基础上 ,通过分析国内外已有高速公路沥青路面的组成及使用状况 ,对高速公路沥青路面的面层、基层和底基层材料选择和合适厚度进行了分析研究 ,为我国高速公路沥青路面设计提供一些建议 .
Some problems will arise if asphalt pavement has been used for several years.The solutions can be considered from structure,material and construction technology. This paper first analyses material choice and appropriate thickness of surface,base,and subbase of asphalt pavement of expressway.Secondly this paper campares and appraises function evaluation structural constitutes of asphalt concrete pavement and its usability by investigating a lot of information of existing expressway asphalt pavement and analyzing their constitutes and function.Furthermore,some suggestions are provided for asphalt pavement design of expressway.
