There is also an application of 150,000 pounds of crack seal. Bid alternates will include pricing for parking lot resurfacing (chip seal and new asphalt) and an additional PMM location. The crack seal portion of this contract shall seal all cracks up to 1.5” in width on the following arterial and rural collector streets: Twin Peaks Rd. from Saguaro Highlands Dr. to Sanders Rd.; Emigh Rd.; Sanders Rd. between Emigh Rd. and Twin Peaks Rd.; Sandario Rd. between I-10 frontage and Moore Rd; The application of crack seal shall continue until the quantities are exhausted.

Crack sealing shall be completed in the fall; it is permissible to have the remainder of the applications completed in the spring. Decker Rd. and a portion of Potvin Ln. will be rehabilitated as part of this contract. The work is referred to as Decker Rd. even though it includes a section of Potvin Ln. Currently Decker Rd.is comprised of 1,320 LF of chip seal and 700 LF of unpaved roadway. The existing chip seal (approximately 1/2” thick) on Decker is to be removed and the entire length (within Town Limits – 2,000 LF) to be paved, 25 feet wide, with 2.5” of PAG 1 arterial mix placed on existing grade compacted to 95%. The contractor is responsible for investigating the depth of the existing paved roadway prior to bidding and basing the bid thereon.

Concrete ford walls (1’x4’) x 400 LF will be placed at wash crossings and the transition point between the new pavement and existing county dirt road. Decker must remain open to traffic at all times. The contractor shall not grade a crown section through the points where drainage crosses the road. Instead, the roadway shall be straight-graded to provide positive drainage across the roadway. The chip seal work to be performed on AZ Pavilions Dr. between Courtney Page Way and Burlingame Rd. must be completed at night due to heavy traffic volumes. It will be permissible to apply all other areas during daylight hours. Bid alternates: Bid alternative A is a stand-alone price request for a PMM application in the Adonis Subdivision.
