Profilograph Correlation with Present Serviceability Index Asphalt Pavements
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, 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 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 miles sections in six different areas of Texas were measured with these devices for the study.
