1 6-02.3(5)G Sampling and Testing Frequency for Temperature, Consistency, <br /> 2 and Air Content <br /> 3 This section's title is revised to read: <br /> 4 <br /> 5 6-02.3(5)G Sampling and Testing for Temperature, Consistency, and Air Content <br /> 6 <br /> 7 The first paragraph is revised to read: <br /> 8 <br /> 9 Concrete properties shall be determined from concrete as delivered to the project and111 <br /> 10 as accepted by the Contractor for placement. The Contracting Agency will perform <br /> 11 acceptance testing on all concrete for temperature, and air content, if applicable. <br /> 12 Concrete that is not self-consolidating concrete will be tested for slump. The following <br /> 13 additional acceptance tests will be performed on self-consolidating concrete: <br /> 14 <br /> 15 1. Slump flow within the target slump flow range. <br /> 16 <br /> 17 2. J ring passing ability less than or equal to 1.5 inches. <br /> 18 <br /> 19 3. VSI less than or equal to 1. <br /> 20 <br /> 21 In the fifth sentence of the second paragraph, "five truck loads" is revised to read "ten truck <br /> 22 loads". <br /> 23 <br /> 24 The second paragraph is supplemented with the following: <br /> 25 <br /> 26 If the remaining quantity to be placed is less than ten truck loads; then a sample shall <br /> 27 be randomly taken from one of the remaining truck loads. <br /> 28 <br /> 29 In the last sentence of the third paragraph, "five truck loads" is revised to read "ten truck <br /> 30 loads". <br /> 31 <br /> 32 6-02.3(5)H Sampling and Testing for Compressive Strength and Initial Curing <br /> 33 The second paragraph is revised to read: <br /> 34 <br /> 35 The Contractor shall provide and maintain a sufficient number of cure boxes in <br /> 36 accordance with WSDOT FOP for AASHTO T 23 for curing concrete cylinders. The cure <br /> 37 boxes shall be readily accessible and no more than 500 feet from the point of <br /> 38 acceptance testing, unless otherwise approved by the Engineer. The Contractor shall <br /> 39 also provide, maintain and operate all necessary power sources and connections <br /> 40 needed to operate the cure boxes. The cure boxes shall be in-place and functioning at <br /> 41 the specified temperature for curing cylinders prior to concrete placement. Concrete ' <br /> 42 cylinders shall be cured in the cure boxes in accordance with WSDOT FOP for <br /> 43 AASHTO T 23. The cure boxes shall have working locks and the Contractor shall <br /> 44 provide the Engineer with one key to each of the locks. Once concrete cylinders are <br /> 45 placed in the cure box, the cure box shall not be disturbed until the cylinders have been <br /> 46 removed. The Contractor shall retain the cure box Temperature Measuring Device log <br /> 47 and provide it to the Engineer upon request. <br /> 48 <br /> 49 The following new paragraph is inserted after the last paragraph: <br /> 50 11151 All cure box costs shall be incidental to the associated item of work. <br /> I <br /> AMENDMENTS TO THE 2014 STANDARD SPECIFICATIONS BOOK <br /> Revised: 8/3/15 <br />
