I 1 <br /> 2 9-03.1(5) Combined Aggregate Gradation for Portland Cement Concrete <br /> 1 3 This section is revised to read: <br /> 4 <br /> 5 As an alternative to using the fine aggregate sieve grading requirements in Section 9- <br /> I <br /> 6 03.1(2)B, and coarse aggregate sieve grading requirements in Section 9-03.1(4)C, a <br /> 7 combined aggregate gradation conforming to the requirements of Section 9-03.1(5)A <br /> 8 may be used. <br /> I9 <br /> 10 9-03.1(5)A Deleterious Substances <br /> 11 This section is revised to read: <br /> I 12 <br /> 13 The amount of deleterious substances in the washed aggregates /8 inch or larger shall <br /> 14 not exceed the values specified in Section 9-03.1(4)A and for aggregates smaller than <br /> I 15 /8 inch they shall not exceed the values specified in Section 9-03.1(2)A. <br /> 16 <br /> 17 9-03.1(5)B Grading <br /> I 18 The first paragraph is deleted. <br /> 19 <br /> 20 9-03.8(7) HMA Tolerances and Adjustments <br /> 21 In the table in item 1, the last column titled "Commercial Evaluation" is revised to read <br /> I22 "Visual Evaluation". <br /> 23 <br /> 24 9-03.11(1) Streambed Sediment <br /> I 25 The following three new sentences are inserted after the first sentence of the first paragraph: <br /> 26 <br /> 27 Alternate gradations may be used if proposed by the Contractor and accepted by the <br /> I <br /> 28 Engineer. The Contractor shall submit a Type 2 Working Drawing consisting of 0.45 <br /> 29 power maximum density curve of the proposed gradation. The alternate gradation shall <br /> 30 closely follow the maximum density line and have Nominal Aggregate Size of no less <br /> I 31 than 11/2 inches or no greater than 3 inches. <br /> 32 <br /> 33 9-03.21(1)B Concrete Rubble <br /> I 34 This section, including title, is revised to read: <br /> 35 <br /> 36 9-03.21(1)B Recycled Concrete Aggregate <br /> I 37 Recycled concrete aggregates are coarse aggregates manufactured from hardened <br /> 38 concrete mixtures. Recycled concrete aggregate may be used as coarse aggregate or <br /> 39 blended with coarse aggregate for Commercial Concrete. Recycled concrete aggregate <br /> 40 shall meet all of the requirements for coarse aggregate contained in Section 9-03.1(4) <br /> I41 or 9-03.1(5). In addition to the requirements of Section 9-03.1(4) or 9-03.1(5), recycled <br /> 42 concrete shall: <br /> 43 <br /> I 44 1. Contain an aggregated weight of less than 1 percent of adherent fines, <br /> 45 vegetable matter, plastics, plaster, paper, gypsum board, metals, fabrics, <br /> 46 wood, tile, glass, asphalt (bituminous) materials, brick, porcelain or other <br /> I <br /> 47 deleterious substance(s) not otherwise noted; <br /> 48 2. Be free of harmful components such as chlorides and reactive materials unless <br /> 49 mitigation measures are taken to prevent recurrence in the new concrete; <br /> I 50 3. Have an absorption of less than 10 percent when tested in accordance with <br /> 51 AASHTO T 85. <br /> 52 <br /> I <br /> I <br /> AMENDMENTS TO THE 2016 STANDARD SPECIFICATIONS BOOK <br /> Revised: 8/1/16 <br />
