San Diego, CA–The City of San Diego will have crews on the ground to repair and resurface roads through its slurry seal program.
Over the next few weeks, Slurry Seal Project S2221 will be resurfacing 32 miles of roadway in and around the communities of Serra Mesa, Linda Vista, Mira Mesa, Sabre Springs, Rancho Bernardo, Rancho Peñasquitos and Pacific Highlands Ranch.
The project will be completed in phases over multiple weeks. During the first two weeks, city crews will resurface roads in the area.
As part of the city’s commitment to providing smooth streets and safer modes of transportation for all, several streets contained in this slurry seal project will receive new bike lane facilities after being resurfaced. Park Village Road and Sabre Springs Parkway will be repurposed to include separated bikeways.
Slurry seal is a cost-effective, pavement preservation method consisting of asphalt emulsion, sand, and rock. This mixture is applied to the street surface at an average thickness of a quarter inch and extends the life of streets that are already in good condition. Slurry seal is often completed in phases over a period of several days or weeks. It provides a durable surface, addresses existing surface distress on streets, and is a vital program in maintaining the City of San Diego’s more than 2,800 miles of roadway.
Preventing the deterioration of streets is key to improving the overall condition of San Diego’s network of streets and reduces the need for more costly asphalt overlay and reconstruction required for badly deteriorated streets.
Streets are selected for resurfacing through a pavement management system that helps to determine when to schedule streets for resurfacing. Each street segment is assigned an Overall Condition Index based on the pavement’s roughness and cracks.
To prioritize street paving, the Overall Condition Index is used in conjunction with other factors, such as traffic volume, road type, maintenance history, other construction projects, and available funding. Repairs are often grouped within a neighborhood to include streets that are in similar condition or performed after other projects, such as pipeline replacement.
