Abstract:

A number of States are beginning to use roughness measurements from the California and Rainhart profilographs for construction control of rigid pavements. A recent Texas study, Research Study 8-10-87-56, provided correlations between Present Serviceability Index (PSI) as obtained from profile measured by the Surface Dynamics Profilometer (SDP), and profile index (PI) obtained between these profilographs for rigid pavements. The PI was computed using the 0.1- and 0.2-inch blanking bands, which are the ones most commonly used for computing PI. This current report provides details on similar study which investigates correlations of PSI with Rainhart and California profilograph PI measurements for asphalt pavements and concrete pavements with asphalt overlays. Two-tenths mile sections in six different areas of Texas were measured with these devices for the study. Additionally, as in the first study, the 0.1 and 0.2 blanking bands were used to compute the PI. In addition to the correlations with PSI, correlations are also provided between each profilograph with one another.
