Referee Testing. 40 Throughout the life of the Project, there may be differences in material test results or statistical 41 sample populations between the IQF and ADOT. It is important to recognize the difference 42 between material quality and statistical validation.
Referee Testing. 36 Throughout the life of the Project, there may be differences in material test results or statistical 37 sample populations between the IQF and ADOT. It is important to recognize the difference 38 between material quality and statistical validation. 39 Material quality is measured by whether a test passes or fails and is an indication of whether the 40 material will perform its intended purpose. Engineering judgment may be used to substantiate 41 the use of material failing to meet the specification if the material still meets the intended 42 purpose. Statistical validation is a measure of whether the OV and Quality Acceptance 43 populations are statistically equal. It does not represent the quality of material being 44 incorporated into the Project. 1 While expected to occur very rarely, disputes over specific test results may be resolved in a 2 reliable, unbiased manner by Referee Testing and evaluation performed by ADOT’s 3 Construction & Materials Group or an independent third-party testing laboratory as appointed by 4 ADOT’s Construction & Materials Group. The decision by ADOT, or its designee, is final.
Referee Testing. In cases of controversy, make analysis in accordance with the method specified for “Salt” in the current “Official Methods of Analysis for the Association of Official Agricultural Chemists.”
Referee Testing. Testing performed by ADOT’s central laboratory to resolve disputes over specific test results between the IQF and ADOT.
Referee Testing. In addition to performing the duties described elsewhere in this document on certain CDA, FCA or DBA projects, ENGINEER may be occasionally asked by STATE and Developer or DB Contractor to perform Referee Testing on other CDA, FCA or DBA projects for which it is not already contracted. Referee testing may need to be used if a Developer or DB Contractor and the Independent Engineer performing OV testing for that CDA, FCA or DBA project were unable to resolve discrepancies between their testing results. DocuSign Envelope ID: D7BC1FFB-B194-404D-9C0A-6D86DAF7A722 WORK AUTHORIZATION NO. CONTRACT FOR ENGINEERING SERVICES THIS WORK AUTHORIZATION is made pursuant to the terms and conditions of Article 5 of Engineering Contract No. (the Contract) entered into by and between the State of Texas, acting by and through the Texas Department of Transportation (the State), and (the Engineer).
Referee Testing. The Materials and Tests Division is the referee laboratory. The Contractor may request referee testing if a “remove and replace” condition is determined based on the Engineer’s test results, or if the differences between Contractor and Engineer test results exceed the maximum allowable difference shown in Table 11 and the differences cannot be resolved. The Contractor may also request referee testing if the Engineer’s test results require suspension of production and the Contractor’s test results are within specification limits. Make the request within five working days after receiving test results and cores from the Engineer. Referee tests will be performed only on the sublot in question and only for the particular tests in question. Allow 10 working days from the time the referee laboratory receives the samples for test results to be reported. The Department may require the Contractor to reimburse the Department for referee tests if more than three referee tests per project are required and the Engineer’s test results are closer to the referee test results than the Contractor’s test results. The Materials and Tests Division will determine the laboratory-molded density based on the molded specific gravity and the maximum theoretical specific gravity of the referee sample. The in-place air voids will be determined based on the bulk specific gravity of the cores, as determined by the referee laboratory and the Engineer’s average maximum theoretical specific gravity for the lot. With the exception of “remove and replace” conditions, referee test results are final and will establish payment adjustment factors for the sublot in question. The Contractor may decline referee testing and accept the Engineer’s test results when the placement payment adjustment factor for any sublot results in a “remove and replace” condition. Placement sublots subject to be removed and replaced will be further evaluated in accordance with Section 3076.6.2.2., “Placement Sublots Subject to Removal and Replacement.”
Referee Testing. Subsection 1101.08.06 of OPSS.PROV 1101 is amended by deleting the first paragraph in its entirety and replacing it with the following: Referee testing by an independent laboratory may be invoked by the Contractor for any lot of PGAC within 5 Days of receiving all the QA test results for the lot. Table 1 is deleted in its entirety and replaced with the following: Table 1 Additional Testing Requirements and Acceptance Criteria for All PGAC Grades (Note 1) PGAC Grade Property and Attributes (Unit) Test Method Results Reported Rounded To The Nearest Acceptance Criteria Major Borderline Rejectable All PGACGrades Ash Content, % by mass of residue (%) LS-227 0.01 ≤ 0.60 > 0.60 and ≤ 0.80 > 0.80 All PGACGrades Except PG58-28 and PG52-34 Non-recoverable creep compliance at 3.2 kPa (Jnr-3.2) (kPa-1) AASHTO T 350 testing conducted at 58°C 0.01 < 4.50 N/A ≥ 4.50 Average percent recovery at 3.2 kPa (R3.2) (%) 0.1 > the lesser of 55.0 or [(29.371)(Jnr-3.2)- 0.2633] N/A ≤ the lesser of 45.0 or [(29.371)(Jnr-3.2)-0.2633-10] Percent difference in non-recoverable creep compliance between 0.1 kPa and 3.2 kPa, Jnrdiff (%) 0.1 Testing carried out for information purposes only PG70-28, PG64-28, PG58-28 CTOD, t (mm) LS-299 0.1 ≥ 10.0 < 6.0 and ≥ 4.0 < 4.0 Low temperature limiting grade (LTLG) (°C) LS-308 0.1 ≤ -28.0 > -25.0 and ≤ -22.0 > -22.0 Notes:1.
