摘　　要：结合福州南三环路湾边至帝封江段提升整治改造项目,通过对旧沥青混凝土面层材料进行现场调查、系统取样、有关性能试验及相关分析和评价,全面了解了旧沥青混凝土路面的材料性能。结果表明,该工程沥青混合料矿料级配不良、沥青含量偏低、力学性能不良、水稳定性和高温稳定性不足、沥青与集料黏附性能差。试验结果为后续路面改造、旧料回收及材料设计提供了科学依据。Based on the upgrading and reconstruction project of south fragment of the third ring road from Wanbian to Difengjiang in Fuzhou,the material properties of old asphalt concrete pavement is comprehensive understood by field survey,systematic sampling,relative experiments,analysis and evaluation for old asphalt concrete pavement.The results indicate that the old asphalt mixture of the project has poor mineral aggregate gradation,low asphalt content,poor mechanical properties,insufficient water stability and high temperature stability,as well as poor adhesion between asphalt and aggregate,which will provide scientific basis for the further existing pavement reconstruction,old mixture recycling and material design.
