When providing DGA for aggregate surfacing, traffic bound base, and maintenance operations conform to the grading requirement in Sizes of Coarse Aggregates table.

805.15 Gradation Acceptance of Non-Specification Coarse

AGGREGATE. Aggregate purchased for Department work must meet the requirements of this section. The Department may accept non-specification aggregate or work according to Subsection 105.04. When the Engineer determines that the aggregate not conforming to gradation requirements may be left in place, the Department will accept the aggregate at a reduction in the Contract unit bid price for the work containing the aggregate according to the following procedures. The Department will not consider these procedures a means to continue accepting non-specification aggregates. The Department will base the reduction on the invoice price for the aggregate at the source. When satisfactory invoices are not furnished, the Department will use current bin prices for that source on file with the Cabinet’s Division of Purchases. The maximum deduction for non-specification material which is allowed to remain in place is 50 percent. When aggregate fails to conform to gradation on more than one sieve, the Department will apply the largest payment reduction of the out-of-specification sieves represented. The Department will define a lot based on the smallest definable quantity of material represented by acceptance test results, either pa ssing results or failing results, or both. Normally, the Department will average all test results for the lot to determine the test result for payment according to the deduction tables. However, when test results are not reasonably uniform the Department will not average the high and low test results within a 805-7 lot. The Department will assign each test result to equal quantities in new smaller lots in proportion to the number of tests representing the original lot. When daily tests are performed, the lot will be a day’s production unless the Department defines a smaller lot. When 2 consecutive lots contain non-specification material, discontinue the use of the aggregate until the Department makes a decision concerning the overall acceptability of the aggregate from that source. The Department will not impose a reduction in payment for quantities less than 50 tons unless the Engineer deems it necessary.

806.01 DECRIPTION. The asphalt materials section covers performance-graded (PG)

binders, emulsified asphalts, cut-back emulsions, and liquid asphalt for cold-patching mixtures. Provide the specified grade of material conforming to the requirements in this section from suppliers listed in the Department ’s List of Approved Materials. Inclusion on the list of approved suppliers is obtained by following the guidelines of the Approved Supplier Certification (ASC) program contained in Kentucky Method (KM) 64-444, by following the guidelines of the Emulsified Asphalt Supplier Certification (EASC) program contained in KM 64-445, or by pretesting and approval. The Department may approve other types of asphalt materials provided they conform to the requirements of the type specified in the contract.

806.02 SAMPLING. The Department will sample all asphalt materials according to KM

64-404.

806.03 PG BINDERS. This subsection covers the requirements and pay schedules for PG

binders.

806.03.01 General Requirements. Provide PG binders conforming to AASHTO M

332 with any differences found in the PG Binder Requirements and Price Adjustment Schedule. Contrary to M 332, PG 76-22 must ha ve a minimum solubility of 97.0 percent. Do not use any form of recycled engine oil, including Recycled Engine Oil Bottoms (REOB), as a modifier in asphalt materials.
