Services are required for approximately one (1) week or two (2) consecutive weeks a year.

The type of materials, equipment and services required by this RFQ are very specialized and the needed materials that involve an asphalt sealant and rejuvenation product are produced in an oil refining facility. This polymer modified liquid emulsification is transferred directly at the manufacturing plant into specialty trucks for delivery. These trucks are outfitted with computerized spray bars and are dedicated for the purpose of transporting and spreading the specialized emulsification. These trucks are not utilized in any other businesses. Therefore, these trucks are not readily available for rental and are owned and operated solely by those vendors who manufacture and distribute this type of emulsification specialty product
