Motorists are asked to use caution in Atascadero while crews work to refresh the asphalt in several spots around town through Sept. 4.
Final road striping is also scheduled for Sept. 10.
Affected are the streets within the Colony at Apple Valley subdivisions, San Luis Avenue and Pueblo Avenue, and El Camino Real from the Vons shopping center to El Bordo Avenue.
The project, which began last week, focuses on a process called micro-surfacing, which is intended to rehabilitate the top half-inch of pavement with new asphalt to extend pavement life and lessen the need for bigger road repairs, according to the city.
The nearly $415,325 project was contracted out by the city to American Asphalt in Fontana.
While no road closures are proposed, the project is being done one lane at a time with additional delays for drying time, according to the city. Cars parked in marked paving areas will be towed.
