The Public Works pavement preservation program identifies city streets that are in need of appropriate surface treatments to extend the life of the street surface. The identified city streets are selected by completing a pavement surface inspection and receiving a pavement condition index rating.

The Public Works Department conducts its major surface treatments twice a year which include oil, slurry, and chip sealants. These sealants are applied in the spring around April and in the fall around November. Residents living in areas targeted for service will be notified 48-hours in advance. In addition to surface treatments, Public Works maintains the roads throughout the year by patching, potholing, crack sealing, and various other methods that help keep our roads safe. For more Information please call (928) 373-4500.

Pavement Surface Treatments

SLURRY SEAL: The application of a mixture of asphalt emulsion, aggregate (small crushed rock), and water to an existing pavement surface that aids in extending the life and quality of our roads. 

OIL SEAL: The application of a thin liquid-oil asphalt emulsion. The mixture is sprayed onto the existing pavement surface to aid in preserving the road, prevent oxidation, and help retain road flexibility. 

CRACK SEAL: The process of sealing cracks with a hot polymer sealant. The main purpose of crack sealing is to prevent moisture from entering the pavement. It is also used to seal cracks prior to surface treatments (slurry and oil seal).

CHIP SEAL: A two-step process which includes first an application of asphalt emulsion, then a layer of aggregate to an existing pavement surface. The aggregate is applied immediately after the asphalt emulsion is applied to the pavement surface.
