Pavement Management Index

The City of Portsmouth has hired Vanasse Hangen Brustlin, Inc (VHB) annually to perform an
update to the City’s pavement management system. This project is part of an on-going
program where the city road conditions are evaluated periodically, the road network
conditions and budget requirements are analyzed, and road paving programs are developed.

In the summer of 2018, VHB resurveyed the pavement condition of 25.1 miles of Portsmouth’s
total 104.2-mile, City-maintained road network. By hiring VHB to resurvey 25% of the City’s
roads each year and updating the roads where maintenance and resurfacing has been
performed, Portsmouth has maintained an up-to-date Pavement Management System.

Under the scope of this project, VHB performed a detailed inspection of the condition of the
pavement on the City maintained roads and has created a database of this information
which can be viewed, edited and analyzed using VHB’s RoadManager™ software. VHB will
deliver this database to staff in the Public Works Department. The data is linked to the City’s
Geographic Information System (GIS), so that thematic maps can be created to display any
of the information in the database.

This report describes the steps taken in this project, the results of the field evaluations, and
compares the results of potential roadway funding scenarios.
