Pavement monitoring: new methods for analyzing longitudinal evenness

The current method of analyzing longitudinal profile data in Germany (based on Power Spectral Density analysis) has been under criticism for some time now, the main reason being the inability to correctly characterize the unevenness in terms of its random, periodic and transient parts on a consistent basis. The paper deals with general approaches and basics in evaluating longitudinal profile data and then describes two new evaluation methods being capable of evaluating the whole range of wavelengths and shapes (irregular, periodic, transient) relevant to longitudinal evenness. Meanwhile both indicators have been included in the national monitoring program and first statistical results for the whole network of primary roads can be presented.
