1 03.8(6). For each HMA mix design accepted by statistical evaluation with greater than <br /> 2 20 percent RAP by weight of HMA or any amount of RAS, the Contractor shall construct <br /> 3 a test section to determine whether the mixture meets the requirements of Sections 9- <br /> 4 03.8(2) and 9-03.8(6). Test sections shall be constructed at the beginning of paving and <br /> 5 will be at least 600 tons and a maximum of 1,000 tons or as approved by the Engineer. <br /> 6 For a test section to be acceptable the pay factor (PF) for gradation, asphalt binder and <br /> 7 Va shall be 0.95 or greater for each constituent and the remaining test requirements in <br /> 8 Section 9-03.8(2) (fracture, uncompacted void, sand equivalent, dust/asphalt ratio, <br /> 9 Hamburg and IDT) shall conform to the requirements of that section. No further wearing <br /> 10 or leveling HMA will be paved on any of the four calendar days following construction of <br /> 11 the test section. The mixture in the test section will be evaluated as a lot with a <br /> 12 minimum of three sublots required. If more than one test section is required, each test <br /> 13 section shall be a separate lot. <br /> 14 <br /> 15 5-04.3(10)A General <br /> 16 In the first paragraph, "checking" and "cracking" are deleted. <br /> 17 <br /> 18 In the third paragraph, the following new sentence is inserted after the second sentence: <br /> 19 <br /> 20 Coverage with a steel wheel roller may precede pneumatic tired rolling. <br /> 21 <br /> 22 In the third paragraph, the following new sentence is inserted before the last sentence: <br /> 23 <br /> 24 Regardless of mix temperature, a roller shall not be operated in a mode that results in <br /> 25 checking or cracking of the mat. <br /> 111 <br /> 26 <br /> 27 5-04.3(10)B1 General <br /> 28 In this section, "Project Engineer" is revised to read "Engineer". <br /> 29 <br /> 30 The first paragraph is revised to read: <br /> 31 <br /> 32 HMA mixture accepted by statistical or nonstatistical evaluation that is used in traffic <br /> 33 lanes, including lanes for ramps, truck climbing, weaving, and speed change, and <br /> 34 having a specified compacted course thickness greater than 0.10-foot, shall be <br /> 35 compacted to a specified level of relative density. The specified level of relative density <br /> 36 shall be a Composite Pay Factor (CPF) of not less than 0.75 when evaluated in <br /> 37 accordance with Section 1-06.2, using a minimum of 91 percent of the maximum <br /> 38 density. The specified level of density attained will be determined by the statistical111 <br /> 39 evaluation of the density of the pavement. The density of the pavement shall be <br /> 40 determined in accordance with WSDOT FOP for WAQTC TM 8 when using the nuclear <br /> 41 density gauge and WSDOT SOP 736 when using cores to determine density. <br /> 42 <br /> 43 The following four new paragraphs are inserted after the first paragraph: <br /> 44 <br /> 45 Tests for the determination of the pavement density will be taken in accordance the <br /> 46 required procedures for measurement by a nuclear density gauge or roadway cores <br /> 47 after completion of the finish rolling. <br /> 48 <br /> 49 If the Contracting Agency uses a nuclear density gauge to determine density the test <br /> 50 procedures FOP for WAQTC TM 8 and WSDOT SOP T 729 will be used on the day the <br /> 51 mix is placed. <br /> 52 <br /> I <br /> AMENDMENTS TO THE 2014 STANDARD SPECIFICATIONS BOOK <br /> Revised: 8/3/15 <br />
