Provide material meeting the requirements of the following table. Ensure each lot number is accompanied by a certification stating conformance with this Subsection.
C.Accessory Items. Use a closed-cell, polyethylene foam, back-up rod that is compatible with the sealant. Ensure no bond or reaction occurs between the back-up rod and sealant.
D.Approvals. Ensure that each lot of sealant is delivered in containers plainly marked with the manufacturer’s name or trademark and a lot number. Ensure that the manufacturer furnishes certified test results of each lot of joint sealant shipped to each project. The Department does not require tests for ozone and UV resistance, or movement capability and adhesion, on every lot, but ensure that every lot is accompanied by certified results of the latest tests performed. Ensure that the manufacturer indicates the date of shipment on each lot. Do not use material after six months from the date of shipment from the manufacturer without first having the material sampled and tested. The Department will take routine check samples of silicone sealant during application and test it to verify the material ’s acceptability. Provide equipment suitable for obtaining representative check samples from the silicone sealant at a frequency determined by the Materials Field Sampling and Testing Manual from the Department’s Division of Materials. The Engineer may accept the foam back-up rod on the project by visual inspection. 807-3 Use rapid-cure silicone sealant conforming to the following table:
1.Allow a cure time of 48 hours at 77 °F and 50 % relative humidity.
807.04 Joint Fillers.

807.05 FIELD TOLERANCES. The Department, according to established criteria, will
allow tolerance limits to be applied to field samples. These limits are incorporated into the price adjustment schedules. These tolerances are for field samples only and will not apply to certification samples.
807.06 ACCEPTANCE. The Department will normally perform field quality acceptance
testing on samples obtained at the project site or Contractor’s storage facility. When required by the Department, the sealer supplier shall send, at his expense, representative samples of materials stored at the source to the Department’s Division of Materials. When the Department accepts materials by pretesting and certification, provide two copies of the bill-of-lading/load ticket with each delivered unit. The bill-of-lading/load ticket, at a minimum, will contain the material’s lot number and a statement of the quantity of materials within each load. In addition, materials pretested by the Department will include the assigned SiteManager identification number in the shipment documentation. The Contractor and Department’s representative will each receive copies at the point of delivery. Do not use materials that are not properly covered by certification or otherwise tested and approved by the Department. When materials not appropriately certified or not conforming to requirements when tested become incorporated into projects, the Engineer will, according to Section 105, evaluate the work affected and require adjustment of pay quantities or corrective work as deemed appropriate.
807.06.01 Acceptance of Non-Specification Joint Materials. Furnish joint materials
purchased for Department work conforming to the requirements of this section. The Department will apply the following procedures only when reasonably acceptable work has been produced using the material in question, as provided in Subsection 105.04. When the use of non-specification material results in an inferior or unsatisfactory product, remove and replace the material at no expense to the Department, or at the Vendor’s expense when materials are purchased directly by the Cabinet. The Department may accept, at a reduced Contract price, joint materials not appropriately certified, or not conforming to the applicable requirements when check-tested, after an evaluation of the work. However, the Department will not consider these procedures as a means to continue accepting non-specification material. The Department will determine the price adjustment based on the delivered cost of the material. When the material is not appropriately certified, the Department may deduct the full cost of the material. When the material fails to conform to the applicable requirements, the Department will normally make deductions according to the pay schedules included in this section. As provided in Subsection 807.04, the Department has established field tolerances for determining the acceptability of failing material at no price deduction. The Department will determine the frequency of check-sampling and testing on pretested material. The Department will make deductions for failing test results based on the average of two check samples representing the material in question. When a sample fails on two or more tests, the Department may add the deductions, but the total deduction will not exceed 100 percent. 807-6 807-7
807.07 TIME LIMITATION ON APPROVALS. The Department will test materials in
storage at the Contractor’s site as deemed necessary. Additionally, the Department will require the retesting, and re-approval, of materials not incorporated into the work according to the time limitations specified in the Materials Field Sampling and Testing Manual from the Department’s Division of Materials. 807-8 SECTION 808 WATERPROOFING MATERIALS
808.01 DESCRIPTION. This section covers materials for use in waterproofing. The
Department may approve other types of waterproofing materials provided they conform to the requirements of the type Contract specifies.
