The report describes the effectiveness of the PCA Road Meter in determining the serviceability of rigid and flexible pavements. The PCA Road Meter is a device installed in a conventional automobile to measure the number and magnitude of vertical deviations per mile of road between the body of the automobile and the center of the rear axle housing. From these measurements, the sum of squares of road-car deviations can be calculated and correlated with Slope Variance of the Chloe Profilometer. The Louisiana Department of Highways installed a Road Meter in one of its passenger automobiles and conducted this study for its own correlations and verification of various influencing factors on the results. The system was tested for accuracy, repeatability, and correlativity to the Chloe Profilometer. (BPR abstract)
