16. Abstract

The objective of this study was to enhance and develop the Pavement Health Track (PHT) Analysis Tool for the FHWA to provide improved performance, recalibrated analysis models, and modeling of maintenance treatments on the pavement remaining service life (RSL), and to improve the graphical user interface and reporting features.

The PHT Analysis Tool is an engineering software application for determining and reporting the health of pavement networks in terms of the pavement's RSL. The PHT Analysis Tool uses performance models recently developed by FHWA for the Highway Economic Requirements System (HERS) and the National Pavement Cost Model (NAPCOM). These pavement models are based on concepts developed under National Cooperative Highway Research Program (NCHRP) Projects 1-37A and 1-40D and included in the Interim American Association of State Highway and Transportation Officials (AASHTO) Mechanistic-Empirical Pavement Design Guide (MEPDG), making them a simplified version of the more complex mechanistic-empirical (ME) set of models and procedures used in the Interim AASHTO MEPDG.

This report presents an overview of the simplified MEPDG models incorporated into the PHT Analysis Tool along with a detailed description of PHT Analysis Tool approaches to determining pavement RSL, a description of the maintenance model, guidance on setting up the PHT Analysis Tool input database from HPMS and other databases, and guidance on setting key parameters for determining overall RSL.
