I <br /> 1 5-04.3(10)C2 HMA Compaction Statistical Evaluation — Acceptance Testing <br /> 2 In the table, "WSDOT FOP for AASHTO T 355" is revised to read "FOP for AASHTO T 355". <br /> 3 <br /> 4 5-04.3(10)C3 HMA.Statistica! Compaction — Price Adjustments <br /> 5 In the first paragraph, "WSDOT FOP for AASHTO T 355" is revised to read "FOP for AASHTO T <br /> 6 355". <br /> 7 <br /> 8 The first sentence in the second paragraph is revised to read: <br /> 9 <br /> 10 For each HMA compaction lot (that is accepted by Statistical Evaluation) which does not <br /> 11 meet the criteria in the preceding paragraph, the compaction lot shall be evaluated in <br /> 12 accordance with Section 1-06.2(2)D5 to determine the appropriate Composite Pay Factor <br /> 13 (CPF). 1 <br /> 14 <br /> 15 The last two paragraphs are revised to read: <br /> 16 <br /> 17 Determine the Compaction Price Adjustment (CPA) from the table below, selecting the <br /> 18 equation for CPA that corresponds to the value of CPF determined above. <br /> 19 <br /> Calculatin• HMA Corn'action Price Adjustment (CPA) <br /> Value of CPF Equation for Calculating CPA <br /> When CPF > 1.00 CPA = [1.00 x (CPF — 1.00)] x Q x <br /> UP <br /> When CPF = 1.00 CPA= $0 <br /> When CPF < 1.0 CPA= [0.60 x (CPF — 1.00)] x Q x <br /> UP <br /> 20 <br /> 21 Where <br /> 22 CPA = Compaction Price Adjustment for the compaction lot ($) <br /> 23 CPF = Composite Pay Factor for the compaction lot (maximum is 1.05) <br /> 24 Q = Quantity in the compaction lot (tons) <br /> 25 UP = Unit price of the HMA in the compaction lot ($/ton) <br /> 26 <br /> 27 5-04.3(10)C4 HMA Statistical Compaction — Requests for Retesting <br /> 28 The first sentence is revised to read: <br /> 29 <br /> 30 For a compaction sublot that has been tested with a nuclear density gauge that did not <br /> 31 meet the minimum of 91.5 percent of the theoretical maximum density in a compaction lot <br /> 32 with a CPF below 1.00 and thus subject to a price reduction or rejection, the Contractor <br /> 33 may request that a core, taken at the same location as the nuclear density test, be used for <br /> 34 determination of the relative density of the compaction sublot. <br /> 35 <br /> 36 5-04.3(13) Surface Smoothness <br /> 37 The second to last paragraph is revised to read: <br /> 38 <br /> 39 When concrete pavement is to be placed on HMA, the surface tolerance of the HMA shall <br /> 40 be such that no surface elevation lies above the Plan grade minus the specified Plan depth <br /> 41 of concrete pavement. Prior to placing the concrete pavement, bring any such irregularities <br /> 42 to the required tolerance by grinding or other means allowed by the Engineer. <br /> 43 <br /> City of Everett Page AM-20 Amendments <br /> Everett Downtown Streetscape Improvement March 22, 2019 <br />
