STUDY CONTRIBUTING TO THE EFFICIENCY OF PAVEMENT INSPECTION USING ROUGHNESS INDICATORS

Abstract

 Pavement inspections carried out on national roads under direct control are basically carried out by ‘visual inspection’, which requires a great deal of work by sub-station staff, so an efficient inspection method is being investigated. This paper investigates the possibility of screening in pavement inspection using ‘roughness indicators’ obtained from connected cars. In the study, the threshold values of roughness indicators for screening were examined using statistical methods (ROC curves, logistic regression), using the extracted ‘pavement inspection result data’ and ‘roughness indicators’ obtained from connected cars, and the validity of the examined threshold values was verified using the ‘screening rate’. From these results, it was confirmed that the ‘roughness index’ can be used as a screening indicator for pavement inspection on single-lane sections.
