The Research and Development Section of the Louisiana Department of Highways has been using a PCA Road Meter to gather information concerning Present Serviceability Indices for the AASHO Correlation Study. the PCA Road Meter has replaced the Chloe Profilometer because the Chole Profilometer had proven undesirable for this purpose for several reasons, primarily slow operational speed and lack of safety.
This study was conducted to correlated the PCA Road Meter in present use with a PCA Road Meter in another vehicle and with a newer device, the Mays Road Meter. The Mays Road Meter was also evaluated for future use, either by the Research and Development Section or by other units of the Louisiana Department of Highways. The BPR Roughometer was included in this study to have a correlation between any of our present roughness measuring devices in order to be able to interchange equipment in case of breakdown or need for comparative results.
A passenger car mounted PCA roadmeter has been correlated with the BPR roughometer used for road roughness testing in Virginia for many years. The res...
The research project was conducted to evaluate the performance of an inexpensive non-contact roughness measuring device, Roughness Surveyor, as well a...
