路面损坏状况指数PCI是沥青路面使用性能指数PQI分项指标之一,路面损坏状况的检测采用快速检测设备检测或人工方法调查,但沥青路面损坏分类和分项较多,无论采用何种方式检测均较为复杂。通过研究PCI与沥青路面使用性能指数PQI其他3个指标路面行驶质量指数RQI、路面车辙深度指数RDI、路面抗滑性能指数SRI的关系,采用未确知聚类预测方法发掘PCI与RQI、RDI、SRI之间的内部联系。通过预测路面破损状况指数PCI,可用于辨识并剔除公路技术状况评定中的不良数据,对于提高公路技术状况评定的工作效率具有重要意义。 Pavement damage status index PCI is one of the indicators of PQI performance index of asphalt pavement, pavement damage status testing using rapid testing equipment testing or manual methods of investigation, but asphalt pavement damage classification and sub-items, no matter what way to detect Are more complicated. The PCI and RQI, RDI and RDI were explored by using the unascertained clustering prediction method to study the relationship between PCI and the other three indexes of PQI, RQI, RDI and SRI of pavement performance index (PQI) Internal links between SRIs. By predicting the pavement damage status index PCI, it can be used to identify and remove the bad data in the highway technical status assessment, which is of great significance for improving the working efficiency of highway technical status assessment.
