基于多线纹理的路面磨耗检测及评价方法

Detection and Evaluation Methods of Pavement Wearing Based on Multi-line Texture

为了对路面磨耗状况进行定量描述,通过大量的文献分析和深入的理论研究,采用主客观相结合的方法,提出了基于三线路面构造深度的路面磨耗快速检测方法,并根据路面构造深度与路面磨耗率的关系,建立了路面磨耗与路面构造深度指数评价模型及评价标准。通过广泛的工程化应用,验证了提出的路面磨耗快速检测和路面磨耗评价方法的正确性。结果表明:所提出的路面磨耗检测和评价方法能有效区分高速公路和普通公路的不同磨耗状况,可为公路管理及公路养护提供参考。

To describe quantitatively pavement wearing condition,through extensive literature reviews and comprehensive theoretical studies,combined with the subjective and objective evaluating methods,a rapid detection method for pavement wearing condition based on tri-line texture depth was proposed.The relationship between pavement texture depth and pavement wearing ratio was also established. Moreover,evaluation model and criterion on pavement wearing condition and pavement texture depth index were proposed.Through various engineering applications,the proposed methods of rapid detection and evaluation of pavement wearing condition were verified.The results show that the proposed detection and evaluation methods can effectively distinguish the different wearing condition of expressway and highway,which provide references for road management and maintenance.
