How healthy is your pavement network? Use the Federal Highway Administration’s (FHWA) new Pavement Health Track (PHT) Analysis Tool to determine the health of your pavement network in terms of the pavement’s remaining service life (RSL). The PHT Analysis Tool uses pavement performance models developed by FHWA for the Highway Economic Requirements System (HERS) and the National Pavement Cost Models. These pavement performance models are simplified versions of the models and procedures used in the American Association of State Highway and Transportation Officials’ Mechanistic-Empirical Pavement Design Guide.
