System Overview

One of the greatest challenges a city faces is maintaining, preserving and restoring its paved streets. Even though transportation/street maintenance is one of the few areas where cities receive regional, state and local monies (TransNet, Measure P, Senate Bill 1 (SB1)), needs continue to exceed available funding. Most public agencies face financial constraints and must make choices about how to spend their limited transportation/maintenance dollars. Every few years, the city hires a consultant to update its Pavement Management System (PMS) to provide an objective assessment of pavement conditions citywide. The state requires a PMS in order for jurisdiction to be eligible for state funding. The PMS assists staff with selecting pavement preservation and rehabilitation strategies to maximize the use of public funds by applying the correct treatment at the appropriate time interval to extend the life of the pavement. It is critical to note that focusing all efforts on restoring poor conditioned roadways does not maximize the use of public funds.

Pavement Condition Index (PCI)

Below are photographs depicting examples of 5 different PCI scores.


PCI = 21	PCI = 40	PCI = 68	PCI = 75	PCI = 95

Bad Condition <----------------------------------------------------------------------------------------------------------------> Good Condition

This process begins with each of the street segments being rated with a Pavement Condition Index (PCI) between 0 and 100 (with 100 being “like new”). The scores translate into six general condition categories, ranging from “Failed” to “Excellent.” Each score range is assumed to warrant a specific type of treatment. Treatments can be thought of in three general categories – seal, overlay, and reconstruct, with reconstruct being a complete rebuilding of the pavement roadway. The computerized Pavement Management System then begins a complicated process of prioritizing Chula Vista’s over 3,000 street segments to determine the most efficient and effective use of anticipated funds over multiple years.

PCI	Condition Category % of Streets	Pavement Treatment	Cost per Square Yard
71-85	61%	Preventive Maintenance (e.g. slurry, chip seal, cape seal)	$12
51-70	23%	Thin overlay (e.g. less than or equal to 2-inch AC)	$33 - $45
26-50	12%	Thick overlay (e.g. Mill & Fill over 2 to 4-inch AC)	$66
0 - 25	4%	Thick overlay (e.g. Mill & Fill 4 to 6-inch AC)	$75

Asphalt Concrete (AC)

The system considers a number of factors to determine priority, including street type and use, (i.e., number of lanes, total traffic volumes, and heavy truck volumes), street pavement condition rating, and the cost effectiveness of various treatment strategies. The end result is a multi-year list (usually a five-year list) of streets and strategies that maximizes citywide pavement life using available and anticipated funding, while preventing streets in good condition from becoming poor and, therefore, more costly to maintain.

The Pavement Management System has determined that about $20 million per year over the next ten years is required to maintain a target overall citywide condition rating, PCI of 80. However, available funds for pavement rehabilitation are estimated to average about $10 to $14 million per year over the next five years. Due to the shortfall between needed and actual funding, the city must also focus on preserving street pavements using less costly maintenance and rehabilitation treatments to ensure those roadways do not continue to degrade into poor conditions. Meanwhile, staff actively searches for alternative funding to re-build and/or reconstruct streets that are beyond repair.

In summary, each year the city’s pavement program will strategically focus on various maintenance and rehabilitation treatments on roadways of varying pavement condition as appropriate. It is critical that streets in good condition also receive less costly preservation treatments such as slurry seal coats in an effort to extend the life of those streets and prevent having to use more expensive pavement rehabilitation treatments in the future. Based on the limited funds available, this is the most cost-effective strategy to maintain the best pavement condition citywide.
