高速公路沥青混凝土路面破损状况评价方法的缺陷及改进

以广东省多条高速公路沥青混凝土路面的路况普查数据为基础,分析了目前我国高速公路沥青混凝土路面破损状况评价方法的诸多不足,在此基础上提出了高速公路沥青混凝土路面破损状况的合理评价指标,即路面车辙代表深度、路面裂缝率以及路面修补率。此外,应用基于三角白化权函数的灰色聚类评估方法对沥青混凝土路面的破损状况进行了综合评定,为我国高速公路沥青混凝土路面养护质量的评定及养护对策的制定提供了参考依据。

Shortcomings and Improvement of Evaluation Methods for Breakdown Condition of Expressway Asphalt Concrete Pavements

On the basis of the data which are collected by the investigation on asphalt concrete pavements of a variety of expressways in Guangdong Province,the shortcomings of the evaluation methods for the breakdown condition of asphalt concrete pavements of expressways in China are analyzed.The reasonable evaluation indexes grounded on the above investigation are proposed,that is,rut represents deepness,crack ratio and repairing ratio of pavements.The evaluation methods for grey polymerization which are grounded on triangle-ablation function further make a comprehensive evaluation for the breakdown condition of asphalt concrete pavement,which provides the reference materials for the evaluation of maintenance quality and the formulation of solution to maintenance of asphalt concrete pavements of expressway in China.
