Research on Asphalt Pavement Inspection Data Quality Evaluation System

Aiming at the accuracy, completeness, and consistency problems that may occur in the actual inspection process of the anti-skid performance, road roughness, rutting and other inspection indicators of expressway asphalt pavement, this paper defined three evaluating indicators, which were data accuracy rate, data consistency rate, and data consistency rate, respectively. And then, an asphalt pavement inspection data quality evaluation system was established. In combination with the data of some sections of expressways in Jiangsu Province and related data over the years, the effectiveness of the corresponding evaluation system was verified through case analysis, and the results showed that the establishment of the inspection data quality evaluation system, can better judge the consistency of the inspection data, data threshold, and data accuracy of each inspection index, so as to provide a solution for quickly identifying abnormal inspection data during expressway asphalt pavement inspection period.
