Abstract

Monitoring surface conditions and prediction of the damage of road surface have been carried out periodically from point of view of the traffic safety and the pavement management system (PMS). Nowadays, the true profile for a specified spatial frequency range can be easily obtained by a profiler although it has inherent detective properties. In this paper, we studied an estimation of the true profile using the measurement data of the PIARC EVEN experiment acquired by a conventional 3m profilometer. The results show that the profilometer enables to estimate the true profile accurately for practical use on general highways.
