2026 Pavement Maintenance Overlay Special Provisions <br />PW# 3860 SP - 61 March 5, 2026 <br />1 5-04.3(9)B Vacant <br />2 <br />3 5-04.3(9)C Mixture Acceptance Nonstatistical Evaluation <br />4 HMA mixture which is accepted by Nonstatistical Evaluation will be evaluated by the <br />5 Contracting Agency by dividing the HMA tonnage into lots. <br />6 <br />7 5-04.3(9)C1 Mixture Nonstatistical Evaluation Lots and Sublots <br />8 A lot is represented by randomly selected samples of the same mix design that will be <br />9 tested for acceptance. A lot is defined as the total quantity of material or work produced <br />10 for each Job Mix Formula placed. Only one lot per JMF is expected. A sublot shall be <br />11 equal to one days production or 800 tons, whichever is less except that the final sublot <br />12 will be a minimum of 400 tons and may be increased to 1200 tons. <br />13 <br />14 All of the test results obtained from the acceptance samples from a given lot shall be <br />15 evaluated collectively. If the Contractor requests a change to the JMF that is approved, <br />16 the material produced after the change will be evaluated on the basis of the new JMF for <br />17 the remaining sublots in the current lot and for acceptance of subsequent lots. For a lot in <br />18 progress with a CPF less than 0.75, a new lot will begin at the Contractors request after <br />19 the Engineer is satisfied that material conforming to the Specifications can be produced. <br />20 <br />21 Sampling and testing for evaluation shall be performed on the frequency of one sample <br />22 per sublot. <br />23 <br />24 5-04.3(9)C2 Mixture Nonstatistical Evaluation Sampling <br />25 Samples for acceptance testing shall be obtained by the Contractor when ordered by the <br />26 Engineer. The Contractor shall sample the HMA mixture in the presence of the Engineer <br />27 and in accordance with AASHTO T 168. A minimum of three samples should be taken for <br />28 each class of HMA placed on a project. If used in a structural application, at least one of <br />29 the three samples shall be tested. <br />30 <br />31 Sampling and testing HMA in a structural application where quantities are less than 400 <br />32 tons is at the discretion of the Engineer. <br />33 <br />34 For HMA used in a structural application and with a total project quantity less than 800 <br />35 tons but more than 400 tons, a minimum of one acceptance test shall be performed. In all <br />36 cases, a minimum of 3 samples will be obtained at the point of acceptance, a minimum of <br />37 one of the three samples will be tested for conformance to the JMF: <br />38 <br />39 •If the test results are found to be within specification requirements, additional <br />40 testing will be at the Engineers discretion. <br />41 <br />42 •If test results are found not to be within specification requirements, additional <br />43 testing of the remaining samples to determine a CPF shall be performed. <br />44
