Add the following sub-section:
302-15 CRACK SEAL
302-15.1 GENERAL
Crack seal material shall conform to 203-17 CRACK SEALANT. 302-15.2 Site Preparation
Treat cracks from ¼ to 2 inch in width for the entire length of the crack. All cracks to be sealed shall be completely clean, dry, and free of all loose material, vegetation, and any other foreign substance which may cause the sealant not to adhere to the crack wall.
The Contractor shall treat all vegetation within the limits of the paved area to receive surface seal treatment with a post emergent herbicide. Herbicide shall be applied at least 5 (five) working days prior to sealing the street. Allowance for the five-day period shall be shown in the schedule required per Section 6-1, Construction Schedule and Commencement of the Work.
Cracks shall be cleaned using a hot compressed air lance (HCL) apparatus. The Contractor shall clean and dry all cracks with the HCL immediately before sealing. Air exiting the lance shall be heated to a DocuSign Envelope ID: F7534773-FF05-4C1A-972F-1488643FB005 temperature sufficient enough to remove the oxidized surface from the crack walls. The HCL shall meet the following requirements:
- Compressed air capacity: 90 PSI min.
- Heated air temperatures: 600 F to 2,200 F
- Exit heated air: 1,000 ft/sec.
- Propane: 5 to 20 PSI
The joints and cracks shall be inspected and approved by the Engineer prior to placing the crack sealant material. Final joint and crack cleaning will be the same day of the sealing operation except as otherwise approved by the Engineer or his designee.
302-15.3 Application
302-15.3.1 Small Cracks (¼ - 1” Wide)
Sealant shall be prepared and applied to the pavement cracks in conformance with all manufacturers’ instructions except where noted otherwise in this document. - Sealant shall be applied when the pavement surface temperature is greater than 50°F. - Containers of hot-melt rubberized sealant shall be delivered to the job-site in unopened containers that are clearly marked with data showing the manufacturer's name, the product designation and the manufacturer's batch number and lot numbers.
- The hot-melt rubberized asphalt shall be melted in a jacketed, double boiler type melting unit. - Application of the hot-melt sealant shall be made with a pressure feed applicator or pour pot. - Sealant shall be applied from the bottom of the crack up to the surface in a manner which does not result in sealant bridging or entrapping air pockets.
- Apply crack treatment with a nozzle inserted into the crack. The sealant shall be applied to a slightly overfilled condition and then leveled with a squeegee. The overband shall not exceed 1” on either side of the crack.
- If after two days the crack treatment is more than 1/4 inch below the specified level, the sealant fails, or the crack re-opens, re-treat the crack.
- Immediately remove crack treatment material that is spilled or deposited on the pavement surface. - Before opening to traffic, apply sand or the manufacturer’s recommended detackifying agent to tacky crack treatment on the traveled way.
- Sweep up excess sand before opening to traffic.
302-15.3.1 Large Cracks (1-2” Wide)
Sealant shall be installed per the manufacturer’s recommendation.
