806.06.01 Asphalt Coating Material . Furnish asphalt coating material

conforming to AASHTO M 190. The Department will obtain random samples of the asphalt coating material for analysis. The Department will reject all material not conforming to AASHTO M 190.

liquid asphalt material furnished under this subsection provides satisfactory coating properties, workability, and adherence characteristics for patching during cold and damp weather in either asphalt or concrete pavement surfaces. Furnish patching mixtures made with liquid asphalt or KP-6 that is capable of being stored for at least 6 months before being used and that is readily workable at all ambient temperatures above 25 F. With each shipment of material, provide test results certifying that the materials furnished conform to the following KP-6 Requirements table. Additionally, take a one- gallon sample from each transport as specified in the Materials Field Sampling and Testing Manual from the Department’s Division of Materials. Ship the sample to the Division of Materials by any expedient means of transport. Obtain the Division of Materials’ approval before using the liquid asphalt. 806-5 KP-6 REQUIREMENT S Property Test Method Specification 100% Pay 90% Pay 80% Pay 60% Pay 0% Pay Flash Point, ˚F AASHTO T 48 ≥ 200 ≥ 195 190 - 194 188-189 186 - 187 ≤ 185 Water, % AASHTO T 55 ≤ 0.2 ≤ 0.5 0.6 – 1.0 1.1 – 1.2 1.3 - 1.5 ≥ 1.6 680 ˚F Distillation AASHTO T 78 Temperature (F) Vol. of Total Distillate, % Vol. of Original Sample, % to 437 None None to 500 0 - 0.5 0 - 5 to 600 10 - 65 0 - 25 Residue From Distillation @ 680 ˚ F(% Volume by Difference) 72 - 95 76-96 Tests on Residue from Distillation Modified Penetration With Cone(1) ASTM D 5 180 min.

806.08 FIELD TOLERANCES. The Department, according to established criteria,

allows 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.

806.09 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 asphalt supplier shall send, at his expense, representative samples of materials stored at the source terminal or refinery to the Department’s Division of Materials. When the Department accepts asphalt materials by pretesting and certification, provide two copies of the bill-of-lading/load ticket with each hauling unit. The bill-of-lading/load ticket will contain the material’s lot number, a statement of the quantity of materials within each load by weight and volume, and other information as required by KM 64-444 or KM 64-445. The Contractor and Department’s representative will each receive copies at the point of delivery. Do not use asphalt materials that are not properly covered by certification or otherwise tested and approved by the Department. When asphalt materials not of the specified grade, not appropriately certified, or not conforming to the applicable 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. 806-6

806.09.01 Acceptance of Non-Specification Asphalt Materials. Furnish asphalt

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 quest ion, 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, asphalt materials not of the specified grade, 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. If the liquid asphalt has been incorporated into the project as an asphalt mixture, the deduction will be applied to the posted price of asphalt item. When the material is not of the specified grade or 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 in this section. As provided in Subsection 806.08, 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. When available, 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.

806.10 TIME LIMITATION ON APPROVALS. The Department will test materials

in storage at the terminal as deemed necessary. Additionally, the Department will require the retesting, and re-approval, of materials not incorporated into the work within one month (2 months for PG binders) of the shipment date. 806-7 SECTION 807  JOINT MATERIALS

807.01 DESCRIPTION. This section covers joint sealers and joint fillers of various types.

The Department may approve other types of joint materials provided they conform to the requirements of the type specified in the Contract.

807.02 SAMPLING. The Department will sample all materials according to the Materials

Field Sampling and Testing Manual from the Department’s Division of Materials.

807.03 Joint Sealers.

807.03.01 Hot-Poured, Elastic Joint Sealers. Furnish hot-poured, elastic joint

sealers that meet or exceed the requirements of ASTM D 6690, Type II and the following table. Provide a certification of conformance with each lot of sealer.
