The Pavement Management System (PMS) of the City of El Paso Department of Transportation is a tool used to prioritize day-to-day street operations and long-term projects. The PMS uses a systematic and repeatable method for collecting and calculating the data and calculating Pavement Condition Index (PCI) values. The Micropaver software used in this process is an accepted industry standard and was developed by the Army Corps of Engineers.
The restoration techniques used to manage the City’s pavement include; patching, crack sealing, asphalt rejuvenation, microsurfacing, resurfacing and reconstruction. The type of repairs a street receives is based on its needs and recommendations from Micropaver.
The PCI is a reflection of the condition of a street’s asphaltic layer and does not include conditions of the curb/gutter, the foundation beneath the asphaltic layer, sidewalks, and drainage associated with the roadway. Data for the PCI is collected periodically and is updated in phases, the first phase occurring in 2003 and the most recent in 2008.
Every street within the city limits has been assessed and assigned a rating based on their respective PCI. Ratings are depicted on a color scale on a PCI map with a corresponding rating: Excellent, Very Good, Good, Fair, Marginal, Poor and Very Poor.
The pavement condition for each street is subject to change due to the multiple factors including but not limited to; weather conditions/cycles, passenger and commercial traffic volumes, design standards used when the street was initially constructed, age of the roadway, drainage, pavement cuts into the street for utility work, and ongoing street rehabilitation projects.
Streets excluded from resurfacing are those requiring full reconstruction for one or more of the following reasons: they are not in compliance with City standards; require drainage systems, is part of an on-site ponding subdivision; are part of local or regional transportation projects; or have poor soil conditions. These streets are identified reconstruction candidates. The process used to make this determination can be seen as a flowchart here: Flowchart for Street Selection
The number of streets resurfaced annually is based on funding allocated to the resurfacing program. Funding levels are determined during the City’s budget process.
