City of South San Francisco Paving Program
The City of South San Francisco is investing $18 million over five years to maintain and repair 138.9 miles of streets. Funded by Measure W, this program prioritizes high-traffic roads classified as "poor" or "very poor." Maintenance strategies include slurry seals, overlays, and surface reconstruction.
Pavement Repair Strategies
Slurry Seal
A thin layer of liquid asphalt applied to extend roadway life. Roads may be closed for 4 to 5 hours post-application.
Microsurfacing
A polymer-modified asphalt emulsion applied to restore road texture and improve skid resistance.
Chip Seal
A layer of asphalt binder sprayed on the road, followed by aggregate chips, improving durability and skid resistance.
Cape Seal
A combination of chip seal and slurry or microsurfacing to provide a strong, smooth, and durable surface.
Micro Milling
Removes a thin layer of pavement to improve smoothness and prepare for resurfacing.
Prep-Work
Includes crack sealing, patching, and surface cleaning to ensure proper bonding of new asphalt layers.
Cold Milling (Grinding)
Removes deteriorated pavement to prepare for overlays or reconstruction.
Hot Mix Asphalt
A durable asphalt mix applied at high temperatures for strong, long-lasting pavement.
Rubberized Hot Mix Asphalt
Incorporates recycled rubber for improved durability, noise reduction, and environmental benefits.
Cold-In-Place Recycling
Reuses existing asphalt material in place, reducing costs and environmental impact.
Full Depth Reclamation (FDR)
Recycles the entire pavement structure, mixing it with a stabilizing agent for a new road base.
Full Depth Reclamation with Lime Treatment
Enhances FDR with lime to strengthen clay-heavy soils and improve durability.
Asphalt Concrete Overlay
A layer of new asphalt placed over existing pavement to restore ride quality and extend pavement life.
Asphalt Concrete Grind and Inlay
Removes and replaces the top asphalt layer in localized sections to repair worn-out areas.
