Abstract:

This paper discusses the use of digital filtering to analyze measured road profiles. Applications of road roughness analysis are given. The discussion of the signal processing operators emphasizes considerations, including pitfalls, that are particularly important. The purpose of filtering is to isolate, for further analysis, the roughness of a given type, e.g., that with 10 to 30-ft (3 to 9-m) wavelengths. Such analysis might include the calculation of measures of overall or average roughness and the most severe roughness in a road section. Both artificial and real test cases are given to compare and demonstrate the capabilities of selected filters. A particular type of filter is recommended on the basis of the test cases. Digital filter design by specification of the squared-magnitude function is emphasized. Selected results from a pilot study in which comparisons are made between hot-mixed asphalt concrete and surface-treated pavements are given to demonstrate the application of the suggested filter and roughness measures.
