Description

Specifications include, but are not limited to: Contractor shall provide all labor, equipment, materials, incidentals and traffic control necessary to produce, haul, place, roll and broom approximately 59,277 square yards of laid-in-place scrub seal. The scrub seal will be approximately 4.21 miles long and 24 feet wide. Contractor shall provide PMRE (Polymer Modified Rejuvenating Emulsion) & Type 1 chips. Traffic control with pilot cars must be maintained until dusk or fading light each workday as determined by the Project Manager. Contractor must provide enough pilot cars to keep traffic stops to a maximum of 15 minutes. Prior to emulsion application, Contractor must ensure roadway is clean and free of debris. All cracks must be dry and blown free of debris to allow emulsion to adhere to the existing crack walls. The emulsion application rate for scrub seals is estimated at .45 gallons per square yard. Following application of the emulsion, use a scrub broom to force the emulsion into the existing surface. The cover material application rate is estimated at 25 pounds per square yard. Actual application rates will be based on the scrub design and the actual field adjustments. If the cover material application rate of 25 pounds per square yard is not sufficient to provide a quality job, the Project Managers will jointly determine what the new application rate should be. Contractor must furnish a water truck for dust control and wetting of chips. Arrangements must be made by the Contractor for acquiring water for wetting and sweeping. It will be the responsibility of the Contractor to determine the centerline and place reflective tabs prior to the scrub seal. The Department will provide final striping.
