Road Condition Assessment Summary

Roadway Asset Services, LLC (RAS) performed a pavement condition assessment for the City of Pueblo, CO to provide an accurate assessment of pavement conditions. The pavement data collection started on January 24, 2022 and completed on March 9, 2022.

The pavement condition assessment included an automated mobile data collection, a Pavement Condition Index (PCI) calculated using RAS’s pavement analysis tool - Technical Rating Intelligence Program (Road TRIPTM), and the delivery of an ESRI file geodatabase. The assessment and conditions rating were performed in general accordance with national standards, where applicable.

The network PCI was determined following the American Society for Testing Materials (ASTM) D6433-11 “Standard Practice for Roads and Parking Lots Pavement Condition Index Surveys” to determine the PCI in combination with the International Roughness Index (IRI).

The City’s roadway network system surveyed as part of this pavement condition project included nearly 500 centerline miles of roadway. Almost 99% of the City’s roads (approximately 493 centerline miles) are asphalt, but there are a few concrete segments as well (approximately 1.6 centerline miles).

RAS’s pavement analysis tool, Road Technical Rating Intelligence Program (Road TRIP™), was used to evaluate and classify the distresses, and calculate the PCI. The PCI is a numerical rating of the pavement condition based on the type, severity, and density of distresses observed on the pavement surface. The PCI is a measure of the overall serviceability provided by a pavement to the vehicle driver. The IRI value is normalized to provide a value between 0 and 100. At the time of this evaluation, the weighted arithmetic average PCI for all roads was 62, which corresponds to a network average of “Fair” condition.
