[ARCHIVED] City Street Sealing Project Begins Friday, Aug. 16

Slow Down Sign

Contractors with the City of Twin Falls will begin sealing city streets Friday, Aug. 16 through Thursday, Aug. 29. The project – known as Fog Sealing – will add necessary oils, resins and plasticizers back into the pavement to protect against the effects of oxidation and weather.

Fog seal work will affect several streets in northwest Twin Falls and will require traffic restrictions, detours, and closures of streets for up to six hours. See for a complete list and map of streets that will be fog sealed. Residents will be notified with door hangers at least 24 hours prior to fog seal work on their streets. Vehicles will not be permitted on sealed streets until the fog seal has cured completely.

Over the years, road pavement and the structure below it start to deteriorate and weaken as a result of traffic volume, rain, snow, and temperature changes. According to the Foundation for Pavement Preservation, as much as 60 percent of the life of asphalt pavement can be lost in its first two years through oxidation. 

To extend the life of the pavement, the City of Twin Falls Street Department preserves the binder that consists of oils, resins and plasticizers. Fog sealing asphalt frequently can keep street surfaces in good condition almost indefinitely and is far less expensive than road reconstruction.

Fog Seal treatment is also considerably less than the cost of a traditional chip and slurry seal; leaves asphalt with a clean black surface and no messy rock chips to clean, and it’s GreenCircle Certified as an environmentally-friendly product.
