A passenger car mounted PCA roadmeter has been correlated with the BPR roughometer used for road roughness testing in Virginia for many years. The results showed a good correlation and that the roadmeter is capable of excellent reproducibility. Roadmeter (Rm) and roughometer (R) roughness are related by the equation R=1.14Rm+25. A temperature correction is necessary if precise roadmeter results are to be obtained. Spectra analysis using the roadmeter is useful in more completely describing roughness characteristics and in defining the most objectionable types of roughness. The roadmeter is recommended for use by the operating divisions of the Highway Department for all future road roughness testing.
South Dakota Road Profiling (SDRP) systems have been widely sanctioned for use in assessing road roughness and rutting at highway speeds. Traditionall...
