Road Repair Projects Underway in the City of San Diego

Slurry seal road repair Collwood Boulevard

The City of San Diego continues to repair and resurface roads through its slurry seal program. Over the next few weeks, resurfacing is scheduled for streets in and around Balboa Park and North Park, along with Otay Mesa, College Area and eastern parts of the City.

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 Diegos more than 2,800 miles of roadway.

Preventing deterioration of streets is key to improving the overall condition of San Diegos 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 the City determine when to schedule streets for resurfacing. Each street segment is assigned an Overall Condition Index (OCI) based on the pavements roughness and cracks.

To prioritize street paving, the OCI 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 similar condition or performed after other projects, such as pipeline replacement.
