Pavement roughness analysis using wavelet theory
W Liu, Tien Fang Fwa, Zhe Z · 2004
This paper presents a wavelet transform analysis procedure to offer supplementary information to the commonly used road summary indices. The proposed wavelet analysis is able to provide useful information for network pavement management and pavement maintenance operations by examining the roughness features at both high and low frequencies. It can be a valuable tool for highway engineers, as a supplement to the International Roughness Index IRI (or any other roughness indices) analysis, to gain more insight into the behavior and performance of highway pavements under their charge.
