An Evaluation System of Pavement Permanent Deformation Based on AASHTO PP69-10 with 1-mm Three-Dimensional Pavement Surface Model
Measurement of pavement rut is critical to highway agencies for both pavement design and rehabilitation. Historically rut depth is the only pavement permanent deformation indicator collected with various measurement technologies. Recently, the new draft protocol called American Association of State Highway and Transportation Officials (AASHTO) Standard Practice PP69-10 outlines a set of procedures to derive multiple measures of pavement permanent deformation, including percent deformation, water entrapment depth, rut depth etc. Multiple parameters can be useful for project-level analysis, but may not be realistic indices for overall permanent deformation evaluation at network level. In this paper a three-step procedure is applied to evaluate the overall permanent deformation. Transverse profile data are collected on over 200km (125 miles) National Highway Systems (NHS) using the 1mm PaveVision3D Ultra data collection system. Twelve permanent deformation attributes are calculated according to the requirement of PP69-10. Scoring functions of these attributes are elicited using utility theory based methods with statistics of attributes from the collected sample data sets. Analytical Hierarchy Process (AHP) is performed for the development of a comprehensive permanent deformation evaluation system. Additive weights are obtained for all attributes based on pairwise comparisons. A case study is conducted to compare current rut depth based practice with the proposed new comprehensive evaluation system.
