0757.16 Acceptance of RCC: <br /> (a) General -Acceptance of RCC will be based on the results of the Engineer's quality <br /> verification testing according to Section 00165. <br /> (b) Aggregate -Acceptance will be based on the Engineer's quality verification testing. „1 <br /> (1) Aggregate Gradation - A stockpile contains specification aggregate gradation when the <br /> quality level for each sieve size calculated according to 00165.40 is equal to or greater than <br /> the quality level indicated in Table 00165-2 for a PF of 1:00. Each required sample <br /> represents a sublot. When the quality level indicated in Table 00165-2 yields a PF of less <br /> than 1.00 for any constituent, the material is non-specification. <br /> (2) Non-specification Aggregate Gradation.- Stockpiled aggregates that contain non- <br /> specification aggregate gradation will be rejected by the Engineer unless non-specification <br /> material is removed from the stockpile. Do not add additional material to the stockpile until <br /> enough non-specification material is removed so that the quality level for each constituent is <br /> equal to or greater than the quality level in Table 00165-2 fora 1.00 PF. <br /> (c) Plastic'RCC -Acceptance of the plastic RCC will be based on the tests performed by <br /> the Engineer, according to the tolerances and limits of 02002.50 and Table 02002-1. <br /> (d) Hardened RCC -Prepare and cure the test specimens according to ASTM C 1435 and <br /> test at 28 days according to AASHTO T 22. - ~ r.~ ~ c ~ _ ~Zvn e . ~ z. <br /> (1) General -For all classes of RCC, acceptance of hardened RCC will be based on an <br /> analysis of compressive strength tests of cylinders performed by the Engineer. <br /> (2) Actual Strength Test Value (28 day) -The ASTV is the average compressive strength <br /> of the three cylinders tested. If the compressive strength of a single test specimen varies by <br /> more than 10% from the average of the other two specimens, that compressive strength <br /> value will be discarded. The average compressive strength test of the two remaining <br /> specimens will be the ASTV. <br /> (3j Sampling. and Testing -Sampling and testing shall be according to the MF'TP. ?h4 ~ oti <br /> r~~~, Tr-.S~ A~~t~~~~~ <br /> (4) Acceptance -The ASTV Shall exceed the f c (specified strength) for the mix design. If <br /> a set of cylinders has an ASTV less than f'c, the Engineer will review the results to <br /> determine if the RCC represented by the cylinders shall be removed. In any case, RCC that <br /> has an ASTV of less than 85% of the specified strength shall be removed unless otherwise <br /> authorized, in writing, by the Engineer. The cost of removal, replacement and all related <br /> work shalt be the Contractor's responsibility, subject-, if the RGC is allowed to remain in <br /> place, to a price adjustment according to 00150,25. <br /> !fan ASTV falls below the f'c, the Contractor may submit a written plan within three days of the <br /> test for review by the Engineer. The plan shall outline a proposed altemate method of <br /> evaluating compressive strength. The plan shall provide evidence that a reasonable f cr (over- <br /> design)was maintained and that there is credible evidence (besides low strength) which <br /> warrants consideration of this option. If the Engineer determines that the compressive strength <br /> <br /> ,test results are suspect from definable external factors, the Engineer may allow an altemate <br /> method of acceptance. <br /> Special Provisions -Job #4317 Page 5 of 26 <br /> f <br /> <br />
