Update of the State Pavement Management System and Implementation of the Mechanistic-Empirical Pavement Design Guide

The Hawaii Department of Transportation (HDOT) needs to update its pavement design procedure and pavement management system (PMS). For new pavement sections, calibration of the Mechanistic-Empirical Pavement Design Guide (MEPDG) was performed with the help of tools developed for development of Historical Pavement Structural Information (HPSI); development of axle load spectra (ALS), number of axles per vehicle, and lane distribution factors; and processing of roughness. Testing of material characteristics was performed, including dynamic modulus (|E*|) of Hot Mix Asphalt (HMA), HMA permanent deformation and fatigue cracking, resilient modulus (Mr), binder testing, permeability of permeable base material, and coefficient of thermal expansion of Portland Cement Concrete (PCC). Local models of |E*| and Mr are examined and the difficulties for selecting Mr, created by non-linearities and environmental effects, are analyzed. Simple rules are presented to select Mr input values. A procedure is presented to limit the number of simulations needed for calibration of the MEPDG for cracking and roughness. In addition, a mechanism for top-down fatigue cracking is postulated. Overall, it is shown that the MEPDG can produce reasonable results for Hawaiian conditions. For implementation, after personnel training, it is recommended to use the MEPDG for a few years in tandem with the current procedure to develop calibration data and getting experience with it. Changes to the HDOT design procedure (e.g., traffic loading) are proposed. For the PMS, it is found that although pavement condition has been collected for years, there has been a lack of consistency in terms of the protocols used, the length and location of the pavement segments, and the calculation of the Pavement Condition Index (PCI). The capabilities of StreetSaver©, RoadSoft©, and PAVER™ were analyzed in detail. It is found that any of these programs (and others) can satisfy HDOT needs if some data issues discussed are overcome. This research advanced the most with PAVER™, for which a network of almost 2,000 pavement sections for Oahu was created and populated. Guidelines for the use of PAVER™ that complement the Users’ Manual have been created as well as a program to prepare the data for import into PAVER™. Consequently, if HDOT select a low cost software for its PMS, the suggested order or preference for adoption is (1) PAVER™, (2) StreetSaver®, and (3) RoadSoft®. Recommendations are provided for solving many PMS and MEPDG issues.
