随着高速公路的发展,现有规范已不能完全适用于高等级公路沥青路面性能的评价,不能反映真实路况。本文结合相关研究现状采用路面车辙代表深度Dr、裂缝率Ck、修补率Lr等指标来表征路面破损技术状况。采用了客观权重的模糊模式识别交叉迭代模型,避免了人为因素的干扰,能够直观的体现出各种因素对路面破损的影响,提高路面破损状况评价方法的科学性和适用性。通过实例分析了解评定过程,并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。
With the development of expressway, the existing norms can not be fully applied to the evaluation of asphalt pavement performance of high-grade highway, and can not reflect the real road conditions. In this paper, the status quo of pavement damage technology is described based on the status quo of relevant research using the representative depth of the rut Dr, crack rate Ck, repair rate Lr and other indicators. The cross-iterative model of fuzzy pattern recognition with objective weight is adopted to avoid the interference of human factors. It can intuitively reflect the influence of various factors on the pavement damage and improve the scientificity and applicability of the pavement damage assessment method. Through the example analysis and understanding of the assessment process, and for the highway asphalt concrete pavement maintenance quality assessment and conservation strategies to provide a reference.
