Exploring AASHTO PP69-10 Rut Parameters with 3D 1mm Pavement Surface Model

摘要: Rut measurement is critical to modern pavement modeling and management. Over the years, rut has been measured with manual or limited-point automated devices. However, such lagging technologies outdated protocols have led “rut depth” only convention, which compromises application of data. Recently, new 3D 1mm surface model produced PaveVision3D Ultra system capable providing engineers full-lane-width high resolution transverse profiles for analysis. Multiple characteristics as area deformation can be consistently derived based on American Association State Highway Transportation Officials (AASHTO) protocol PP69-10. To provide insight into PP69-10 parameters, bulks profile data collected from Arkansas National Systems (NHS) are analyzed in this study. The value range parameter modeled. relationship depth traditional method established. correlations among different attributes examined. Results presented study will helpful highway agencies shifting state practice measurement.
