What is Pavement Preservation?
Pavement Preservation is a cost-effective way to maintain our roads. This program is designed to take direction through funding allocation from Pinal County and the Board of Supervisors. Such a program can vary annually depending on funding available. The overall goal is to have a long-term strategy that enhances pavement performance by having cost-effective practices and treatments to extend pavement life, improve safety and satisfy the needs of our motorists.

There Are Various Types of Treatments to Extend Pavement Life

Chip Seal - a preventive maintenance surface treatment entailing a single application of asphalt emulsion by a distributor followed by a cover aggregate applied by a chip spreader. The surface is then rolled to seat the aggregate.

Crack Seal - a preventive technique in which a crack is prepared cleaned, dried and a high quality sealant material is placed into cracks to prevent infiltration of water into the underlying pavement layers.
Fog Seal - a light application of diluted emulsion sprayed on an existing asphalt surface to enrich aging, weathered surfaces. Fog seals are also used to reduce chip loss on chip seals.

Slurry Seal - a preventive or corrective maintenance surface treatment composed of a mixture of aggregate, emulsified asphalt, mineral filler, additives and water. The slurry seal improves road surface texture and seals and protects the pavement.

Microsurfacing - a skid resistant surface treat-ment composed of a mixture of polymer modi-fied asphalt emulsion, well graded aggregate, mineral filler, water and other additives. Microsurfacing cures more quickly than slurry seal allowing for a thicker application.

Such treatments, plans, and progress 
may vary depending on funding available.
