4-23 factor for PGAB Content, VMA at Ndesign, and Voids at N design shall be 0.70. If the PGAB content falls below 0.80 for Method C, then the PGAB pay factor shall be 0.55. The following variables will be used for pay adjustment: PA = Pay Adjustment Q = Quantity represented by PF in ton P = Contract price per ton PF = Pay Factor The Department will determine a pay adjustment using Table 11: Pay Adjustment Calculations as follows: TABLE 11: PAY ADJUSTMENT CALCULATIONS Acceptance Method Mix Properties / Gradation Density Method A PA = (Voids @ N d PF- 1.0)(Q)(P)x0.20 + (VMA at N design PF- 1.0)(Q)(P)x0.20 + (PGAB Content PF- 1.0)(Q)(P)x0.10 PA = (density PF- 1.0)(Q)(P)x0.50 Method B Method C PA = (% Passing Nom. Max PF-1.0)(Q)(P)x0.05+(% passing 2.36 mm PF- 1.0)(Q)(P)x0.05+(%passing 0.30 mm PF-1.0)(Q)(P)x0.05+(%passing 0.075 mm PF-1.0)(Q)(P)x0.10+(PGAB Content PF-1.0)(Q)(P)x0.25 In addition, for 9.5 mm NMAS mixtures the following pay adjustm ent shall also apply: The average percent passing for the 0.075 mm sieve shall be eva luated for each Lot. If the average is greater than 6.5%, a pay adjustment according to Table 12 below shall apply in addition to the other pay adjustments for the given method o f testing. TABLE 12: 0.075 MM SIEVE PAY ADJUSTMENT Average Percent Passing 0.075 mm Sieve Pay Adjustment 6.6% - 7.0% -5% > 7.0% -10% The Department shall notify the Contractor whenever the average of at least three samples in a given Lot is greater than 6.5%.
401.21 Acceptance Method D Unless otherwise stated in the 403 special provision, one
sample will be taken from the paver hopper or the truck body pe r 250 ton per pay item. The mix will be tested for gradation and PGAB content. Disputes wi ll not be allowed. If the mix is within the tolerances listed in Table 13, the Department wil l pay the contract unit price. Contractor shall cut two 6 in cores, which shall be tested for percent TMD per AASHTO T- 269 unless otherwise noted in Section 403 - Hot Mix Asphalt Pav ement. If the average for the two tests falls below 92.5% the disincentive shall apply. I f the test results for each 250 ton increment are outside these limits, the following deduction s shall apply to the HMA quantity represented by the test. 4-24 TABLE 13: METHOD D ACCEPTANCE LIMITS AND PAY ADJUSTMENTS Property USL and LSL Pay Adjustment Percent Passing 4.75 mm and larger sieves Target +/-7% N/A Percent Passing 2.36 mm sieve Target +/-7% -2.0% Percent Passing 1.18 mm sieve Target +/-5% N/A Percent Passing 0.60 mm sieve Target +/-4% N/A Percent Passing 0.30 mm sieve Target +/-3% -1.0% Percent Passing 0.075 mm sieve Target +/-3% -2.0% PGAB Content Target +/-0.5% -5.0% % TMD (In-place Density) LSL of 92.5% -10.0% If test results do not meet the Table 13 requirements, deducts as shown shall be applied to the quantity of mix represented by the test.
401.22 Method of Measurement The Department will measure Hot M ix Asphalt
Pavement by the ton in accordance with Section 108.1 - Measurem ent of Quantities for Payment.
401.23 Basis of Payment The Depar tment will pay for the work, in place and accepted, in
accordance with the applicable sections of this Section, for ea ch type of HMA specified. The Department will pay for t he work specified in Section 401.1 2, for the HMA used, except that cleaning objectionable material from the pavement a nd furnishing and applying bituminous material to joints and contact surfaces is incidenta l. Payment for this work under the appropriate pay items shall be full compensation for all la bor, equipment, materials, and incidentals necessary to meet all related contract requirements , including design of the JMF, implementation of the QCP, obtaining core samples, transporting cores and samples, filling core holes, applying emulsified asphalt to joints, and providin g testing facilities and equipment. The Department will make a pay adjustment for qualit y as specified in Section
401.20 Acceptance Met hod A, B & C or 401.21 A cceptance Method D.
401.24 Proce ss for Dispute Resolution (Methods A, B, & C only) At the time of Hot-
Mix Asphalt sampling, the Department will obtain a split sample of each Acceptance test random sample for possible dispute resolution testing. The Con tractor shall also obtain a split sample of the HMA at this same time. If the Contractor wi shes to retain the option of requesting dispute testing of the initial Acceptance sample, th e Contractor will test their split of the Acceptance sample and shall report their results to the Resident, with a copy to Contractor.mainedot@maine .gov by 7:00 AM, on the second working day from time of QA sampling, otherwise dispute resolution will not be initiated. The Department’s dispute resolution split sample will be properly labeled and stored for a period of at least two weeks after it has been reported, or until the sample is tested. The properties eligible for dispute and the respective variances are shown in Table 14. The Contractor may dispute the Department’s Acceptance results and request that the dispute resolution split sample be tested by notifying the Depa rtment’s Resident and QA
