Each strip of HMA placed during a 7 work shift shall conform to a single JMF established for the class of HMA specified unless 8 there is a need to make an adjustment in the JMF. 9 10 5-04.3(8) Aggregate Acceptance Prior to Incorporation in HMA 11 For HMA accepted by nonstatistical evaluation the aggregate properties of sand equivalent, 12 uncompacted void content and fracture will be evaluated in accordance with Section 3-04. 13 Sampling and testing of aggregates for HMA accepted by commercial evaluation will be at 14 the option of the Engineer. 15 16 5-04.3(9) HMA Mixture Acceptance 17 Acceptance of HMA shall be as provided under nonstatistical, or commercial evaluation. 18 19 Nonstatistical evaluation will be used for the acceptance of HMA unless Commercial 20 Evaluation is specified. 21 22 Commercial evaluation will be used for Commercial HMA and for other classes of HMA in 23 the following applications: sidewalks, road approaches, ditches, slopes, paths, trails, gores, 24 prelevel, temporary pavement, and pavement repair. Other nonstructural applications of 25 HMA accepted by commercial evaluation shall be as approved by the Engineer. Sampling 26 and testing of HMA accepted by commercial evaluation will be at the option of the Engineer. 27 28 The mix design will be the initial JMF for the class of HMA. The Contractor may request a 29 change in the JMF. Any adjustments to the JMF will require the approval of the Engineer 30 and may be made in accordance with this section. 31 32 HMA Tolerances and Adjustments 33 1. Job Mix Formula Tolerances – The constituents of the mixture at the time of 34 acceptance shall be within tolerance. The tolerance limits will be established as 35 follows: 36 For Asphalt Binder and Air Voids (Va), the acceptance limits are determined by 37 adding the tolerances below to the approved JMF values. These values will 38 also be the Upper Specification Limit (USL) and Lower Specification Limit (LSL) 39 required in Section 1-06.2(2)D2 40 Property Non-Statistical Evaluation Commercial Evaluation Asphalt Binder +/- 0.5% +/- 0.7% Air Voids, Va 2.5% min. and 5.5% max N/A 41 42 City of Pasco September 2020 19073 WATER MAIN REPLACEMENT – ALLEY EAST OF WEHE AVE SP-72 For Aggregates in the mixture: 1 a.

A lot is defined as the total quantity of material or work produced for 32 each Job Mix Formula placed. Only one lot per JMF is expected. A sublot shall be equal to 33 one day’s production or 800 tons, whichever is less except that the final sublot will be a 34 minimum of 400 tons and may be increased to 1200 tons. 35 36 All of the test results obtained from the acceptance samples from a given lot shall be 37 evaluated collectively. If the Contractor requests a change to the JMF that is approved, the 38 material produced after the change will be evaluated on the basis of the new JMF for the 39 remaining sublots in the current lot and for acceptance of subsequent lots. For a lot in 40 progress with a CPF less than 0.75, a new lot will begin at the Contractor’s request after the 41 Engineer is satisfied that material conforming to the Specifications can be produced. 42 43 Sampling and testing for evaluation shall be performed on the frequency of one sample per 44 sublot. 45 City of Pasco September 2020 19073 WATER MAIN REPLACEMENT – ALLEY EAST OF WEHE AVE SP-73 1 5-04.3(9)C2 Mixture Nonstatistical Evaluation Sampling 2 Samples for acceptance testing shall be obtained by the Contractor when ordered by the 3 Engineer. The Contractor shall sample the HMA mixture in the presence of the Engineer 4 and in accordance with AASH-TO T 168. A minimum of three samples should be taken for 5 each class of HMA placed on a project. 6 7 5-04.3(9)C3 Mixture Nonstatistical Evaluation – Acceptance Testing 8 Testing of HMA for compliance of Va will at the option of the City. If tested, compliance of Va 9 will use WSDOT SOP 731. 10 11 Testing for compliance of asphalt binder content will be by WSDOT FOP for AASHTO T 12 308. 13 14 Testing for compliance of gradation will be by FOP for WAQTC T 27/T 11. 15 16 5-04.3(9)C4 Mixture Nonstatistical Evaluation – Pay Factors 17 For each lot of material falling outside the tolerance limits in 5-04.3(9), the City will 18 determine a Composite Pay Factor (CPF) using the following price adjustment factors: 19 20 Table of Price Adjustment Factors Constituent Factor “f” All aggregate passing: 1½″, 1″, ¾″, ½″, ⅜″ and No.4 sieves 2 All aggregate passing No. 8 sieve 15 All aggregate passing No. 200 sieve 20 Asphalt binder 40 Air Voids (Va) (where applicable) 20 21 Each lot of HMA produced under Nonstatistical Evaluation and having all constituents falling 22 within the tolerance limits of the job mix formula shall be accepted at the unit Contract price 23 with no further evaluation. When one or more constituents fall outside the nonstatistical 24 tolerance limits in the Job Mix Formula shown in Table of Price Adjustment Factors, the lot 25 shall be evaluated in accordance with Section 1-06.2 to determine the appropriate CPF. 26 The nonstatistical tolerance limits will be used in the calculation of the CPF and the 27 maximum CPF shall be 1.00. When less than three sublots exist, backup samples of the 28 existing sublots or samples from the Roadway shall be tested to provide a minimum of three 29 sets of results for evaluation. 30 31 5-04.3(9)C5 Vacant 32 33 5-04.3(9)C6 Mixture Nonstatistical Evaluation – Price Adju stments 34 For each lot of HMA mix produced under Nonstatistical Evaluation when the calculated CPF 35 is less than 1.00, a Nonconforming Mix Factor (NCMF) will be determined. The NCMF 36 equals the algebraic difference of CPF minus 1.00 multiplied by 60 percent. The total job 37 City of Pasco September 2020 19073 WATER MAIN REPLACEMENT – ALLEY EAST OF WEHE AVE SP-74 mix compliance price adjustment will be calculated as the product of the NCMF, the quantity 1 of HMA in the lot in tons, and the unit Contract price per ton of mix. 2 3 If a constituent is not measured in accordance with these Specifications, its individual pay 4 factor will be considered 1.00 in calculating the Composite Pay Factor (CPF). 5 6 5-04.3(9)C7 Mixture Nonstatistical Evaluation - Retests 7 The Contractor may request a sublot be retested. To request a retest, the Contractor shall 8 submit a written request within 7 calendar days after the specific test results have been 9 received. A split of the original acceptance sample will be retested. The split of the sample 10 will not be tested with the same tester that ran the original acceptance test. The sample will 11 be tested for a complete gradation analysis, asphalt binder content, and, at the option of the 12 agency, Va. The results of the retest will be used for the acceptance of the HMA in place of 13 the original sublot sample test results. The cost of testing will be deducted from any monies 14 due or that may come due the Contractor under the Contract at the rate of $500 per sample. 15 16 5-04.3(9)D Mixture Acceptance – Commercial Evaluation 17 If sampled and tested, HMA produced under Commercial Evaluation and having all 18 constituents falling within the tolerance limits of the job mix formula shall be accepted at the 19 unit Contract price with no further evaluation. When one or more constituents fall outside 20 the commercial tolerance limits in the Job Mix Formula shown in 5-04.3(9), the lot shall be 21 evaluated in accordance with Section 1-06.2 to determine the appropriate CPF. The 22 commercial tolerance limits will be used in the calculation of the CPF and the maximum CPF 23 shall be 1.00. When less than three sublots exist, backup samples of the existing sublots or 24 samples from the street shall be tested to provide a minimum of three sets of results for 25 evaluation. 26 27 For each lot of HMA mix produced and tested under Commercial Evaluation when the 28 calculated CPF is less than 1.00, a Nonconforming Mix Factor (NCMF) will be determined. 29 The NCMF equals the algebraic difference of CPF minus 1.00 multiplied by 60 percent. The 30 Job Mix Compliance Price Adjustment will be calculated as the product of the NCMF, the 31 quantity of HMA in the lot in tons, and the unit Contract price per ton of mix. 32 33 If a constituent is not measured in accordance with these Specifications, its individual pay 34 factor will be considered 1.00 in calculating the Composite Pay Factor (CPF). 35 36 5-04.3(10) HMA Compaction Acceptance 37 HMA mixture accepted by nonstatistical evaluation that is used in traffic lanes, including 38 lanes for intersections, ramps, truck climbing, weaving, and speed change, and having a 39 specified compacted course thickness greater than 0.10-foot, shall be compacted to a 40 specified level of relative density. The specified level of relative density shall be a 41 Composite Pay Factor (CPF) of not less than 0.75 when evaluated in accordance with 42 Section 1-06.2, using a LSL of 92.0 (minimum of 92 percent of the maximum density). The 43 maximum density shall be determined by WSDOT FOP for AASHTO T 729. The specified 44 level of density attained will be determined by the evaluation of the density of the pavement. 45 The density of the pavement shall be determined in accordance with WSDOT FOP for 46 WAQTC TM 8, except that gauge correlation will be at the discretion of the Engineer, when 47 using the nuclear density gauge and WSDOT SOP 736 when using cores to determine 48 density. 49 50 City of Pasco September 2020 19073 WATER MAIN REPLACEMENT – ALLEY EAST OF WEHE AVE SP-75 Tests for the determination of the pavement density will be taken in accordance with the 1 required procedures for measurement by a nuclear density gauge or roadway cores after 2 completion of the finish rolling. 3 4 (June 26, 2020 COP GSP) 5 Supplement this section with the following: 6 7 The test procedures FOP for WAQTC TM 8 and WSDOT SOP T 729 will be used on the day 8 the mix is placed and prior to opening to traffic. 9 10 Two (2) density tests shall be taken within the first one hundred (100) tons of asphalt 11 delivered to the site each day and one (1) every 100 tons thereafter for the remainder of the 12 day. If the asphalt fails any test, the City will require additional testing to determine the 13 extent of the failure and more frequent tests may be required on additional asphalt. Testing 14 and samples shall be in accordance with Section 1-06.2(1). 15 16 In addition to randomly selected density test locations, the City may also isolate any area 17 that is suspected of being defective in relative density, and may require additional testing at 18 the Contractor’s expense. 19 20 HMA for preleveling shall be thoroughly compacted. HMA that is used for preleveling wheel 21 rutting shall be compacted with a pneumatic tire roller unless otherwise approved by the 22 City. 23 24 (June 26, 2020 COP GSP) 25 Revise this section from the APWA GSP and replace it with the following: 26 27 Test Results 28 HMA testing shall be pre-arranged and oil content results reported within two (2) hours of 29 sampling. Initial reports may be by phone, subsequent written documents shall be 30 submitted to the City prior to the next day’s paving shift. 31 32 5-04.3(10)A HMA Compaction – General Compaction Requirements 33 Compaction shall take place when the mixture is in the proper condition so that no undue 34 displacement, cracking, or shoving occurs. Areas inaccessible to large compaction 35 equipment shall be compacted by other mechanical means. Any HMA that becomes loose, 36 broken, contaminated, shows an excess or deficiency of asphalt, or is in any way defective, 37 shall be removed and replaced with new hot mix that shall be immediately compacted to 38 conform to the surrounding area. 39 40 The type of rollers to be used and their relative position in the compaction sequence shall 41 generally be the Contractor’s option, provided the specified densities are attained. Unless 42 the Engineer has approved otherwise, rollers shall only be operated in the static mode when 43 the internal temperature of the mix is less than 175°F. Regardless of mix temperature, a 44 roller shall not be operated in a mode that results in checking or cracking of the mat. Rollers 45 shall only be operated in static mode on bridge decks. 46 47 5-04.3(10)B HMA Compaction – Cyclic Density 48 (******) 49 50 City of Pasco September 2020 19073 WATER MAIN REPLACEMENT – ALLEY EAST OF WEHE AVE SP-76 Low cyclic density areas are defined as spots or streaks in the pavement that are less than 1 90 percent of the theoretical maximum density. The City may evaluate the HMA pavement 2 for low cyclic density at their discretion, and when doing so will follow WSDOT SOP 733. 3 Should the City accept a section of pavement with low cyclic density areas, a Cyclic Density 4 Price Adjustment may be assessed at the discretion of the City. 5 6 5-04.3(10)C Vacant 7 8 5-04.3(10)D HMA Nonstatistical Compaction 9 10 5-04.3(10)D1 HMA Nonstatistical Compaction – Lots and Sublots 11 HMA compaction which is accepted by nonstatistical evaluation will be based on acceptance 12 testing performed by the City dividing the project into compaction lots. 13 14 A lot is represented by randomly selected samples of the same mix design that will be 15 tested for acceptance. A lot is defined as the total quantity of material or work produced for 16 each Job Mix Formula placed. Only one lot per JMF is expected. A sublot shall be equal to 17 one day’s production or 400 tons, whichever is less except that the final sublot will be a 18 minimum of 200 tons and may be increased to 800 tons. Testing for compaction will be at 19 the rate of 5 tests per sublot per WSDOT T 738. 20 21 The sublot locations within each density lot will be determined by the Engineer. For a lot in 22 progress with a CPF less than 0.75, a new lot will begin at the Contractor’s request after the 23 Engineer is satisfied that material conforming to the Specifications can be produced. 24 25 HMA mixture accepted by commercial evaluation and HMA constructed under conditions 26 other than those listed above shall be compacted on the basis of a test point evaluation of 27 the compaction train. The test point evaluation shall be performed in accordance with 28 instructions from the Engineer.

HMA that is used to prelevel wheel ruts 32 shall be compacted with a pneumatic tire roller unless otherwise approved by the Engineer. 33 34 5-04.3(10)D2 HMA Compaction Nonstatistical Evaluation – Acceptance Testing 35 The location of the HMA compaction acceptance tests will be randomly selected by the 36 Engineer from within each sublot, with one test per sublot. 37 38 5-04.3(10)D3 HMA Nonstatistical Compaction – Price Adjustments 39 For each compaction lot with one or two sublots, having all sublots attain a relative density 40 that is 92 percent of the reference maximum density the HMA shall be accepted at the unit 41 Contract price with no further evaluation. When a sublot does not attain a relative density 42 that is 92 percent of the reference maximum density, the lot shall be evaluated in 43 accordance with Section 1-06.2 to determine the appropriate CPF. The maximum CPF shall 44 be 1.00, however, lots with a calculated CPF in excess of 1.00 will be used to offset lots with 45 CPF values below 1.00 but greater than 0.90. Lots with CPF lower than 0.90 will be 46 evaluated for compliance per 5-04.3(11). Additional testing by either a nuclear moisture-47 density gauge or cores will be completed as required to provide a minimum of three tests for 48 evaluation. 49 50 City of Pasco September 2020 19073 WATER MAIN REPLACEMENT – ALLEY EAST OF WEHE AVE SP-77 For compaction below the required 92% a Non-Conforming Compaction Factor (NCCF) will 1 be determined. The NCCF equals the algebraic difference of CPF minus 1.00 multiplied by 2 40 percent. The Compaction Price Adjustment will be calculated as the product of CPF, the 3 quantity of HMA in the compaction control lot in tons, and the unit Contract price per ton of 4 mix. 5 6 5-04.3(11) Reject Work 7 8 5-04.3(11)A Reject Work General 9 Work that is defective or does not conform to Contract requirements shall be rejected. The 10 Contractor may propose, in writing, alternatives to removal and replacement of rejected 11 material. Acceptability of such alternative proposals will be determined at the sole discretion 12 of the Engineer. HMA that has been rejected is subject to the requirements in Section 1-13 06.2(2) and this specification, and the Contractor shall submit a corrective action proposal to 14 the Engineer for approval. 15 16 5-04.3(11)B Rejection by Contractor 17 The Contractor may, prior to sampling, elect to remove any defective material and replace it 18 with new material. Any such new material will be sampled, tested, and evaluated for 19 acceptance. 20 21 5-04.3(11)C Rejection Without Testing (Mixture or Compaction) 22 The Engineer may, without sampling, reject any batch, load, or section of Roadway that 23 appears defective. Material rejected before placement shall not be incorporated into the 24 pavement. Any rejected section of Roadway shall be removed. 25 26 No payment will be made for the rejected materials or the removal of the materials unless 27 the Contractor requests that the rejected material be tested. If the Contractor elects to have 28 the rejected material tested, a minimum of three representative samples will be obtained 29 and tested. Acceptance of rejected material will be based on conformance with the 30 nonstatistical acceptance Specification. If the CPF for the rejected material is less than 31 0.75, no payment will be made for the rejected material; in addition, the cost of sampling and 32 testing shall be borne by the Contractor. If the CPF is greater than or equal to 0.75, the cost 33 of sampling and testing will be borne by the City. If the material is rejected before 34 placement and the CPF is greater than or equal to 0.75, compensation for the rejected 35 material will be at a CPF of 0.75. If rejection occurs after placement and the CPF is greater 36 than or equal to 0.75, compensation for the rejected material will be at the calculated CPF 37 with an addition of 25 percent of the unit Contract price added for the cost of removal and 38 disposal. 39 40 5-04.3(11)D Rejection - A Partial Sublot 41 In addition to the random acceptance sampling and testing, the Engineer may also isolate 42 from a normal sublot any material that is suspected of being defective in relative density, 43 gradation or asphalt binder content.
