CONSTRUCTION AND VERIFICATION OF PAVEMENT CRACK PREDICTION CURVE FOR REPRESENTATIVE SECTION OF EACH NATIONAL HIGHWAY OFFICE AND ROUTE

Abstract

 This study shows the result of constructed and verified the pavement crack prediction curve for representative points considering utility of the pavement crack prediction curve at the management site which was indicated in the previous research titled Construction and verification of pavement crack prediction curve concerning representative parts by region and condition.¹⁾ A number of studies has addressed probabilistic crack prediction predictions to support with the uncertainty crack prediction process. However, there are not many research results verified by the actual measurement results for the analyzed crack prediction prediction. In this study, considering the utility of the pavement crack prediction curve at the management site, we constructed the pavement crack prediction curve using the road surface property measurement results extracted the representative points for each route in each national road office within the jurisdiction of the Kanto Regional Development Bureau. In the verification, we compared with the previous research and created a tool that can be used at the management site.
