Road Maintenance

The streets in Turlock vary in their age and condition. Newer streets are generally in better condition and both easier and cheaper to maintain through maintenance treatments such as a slurry seal. Older streets are generally in worse condition with repairs requiring an overlay or complete reconstruction. The limited resources are stretched further when they can be applied towards prevention as opposed to overlays or reconstruction. The goal of the City is to increase the overall, average Pavement Condition Index (PCI) of the City's transportation network to a point where it can be readily maintained in a cost-effective manner.

The most common type of maintenance activity performed across large portions of roadway surfaces in the City is a slurry seal. Unlike an overlay, which is comprised of 1-1/2" to 2" of asphalt and results in a new roadway surface, a slurry seal is a mixture of oil, water, asphalt emulsion, aggregate (very small crushed rock), and is placed on top of an existing asphalt pavement surface. This treatment does not drastically improve the condition of the road, but regular applications of maintenance treatments can extend the life of a road by many years.
