� � i 1 When more than one JMF is being utilized to produce HMA, lhe material 2 produced fur each JMF, shall be placed by separate spreading and compacting [ 3 equipment. ( 4 5 5-04.3(10) Compaction 6 ' 7 5-04.3(10)A Genera/ 8 Immediateiy after the HMA mixture has been spread, slruck off, and surface I 9 irregularities adjusted, it shall be thoroughiy and unifortnly compacted. The 10 completed course shall be free from ridges, ruts, humps, dEpressions, 11 objectionable marks, or irregularities and in conforrnance with the line, grade, � 12 and cross-section shoNn in the Plans or as established by the Engineer. I( 13 necessary, the mix design may be altered to achieve desired results. ' 14 15 Compaction shall take place when the HMA is in the proper condition so that no I 16 undue displacement, cracking, or shoving occurs. All compaction units shall be � 17 operated at the speed, within specification limits, that will produce ttia required 18 compaction. Freas inaccessibla to large compaclion equipment shall be � �9 compacted by mechanical or hand taroers. Any HMA that becomes loose, 20 broke�'�, contaminated, shnws an excess or defi�iency of asphal( binder, or is in 21 any way defective, shali be removed and replaced at no additional cust with � 22 fresh HMA which shall be immediately compacted to conform with the 23 surrounding area. 24 : 25 The type of rollers to be used and their relative posilion in the compaciion ' 26 sequence shali generally be the Contrac'or's option, provided specification 27 �ensities are attained.An exception shall be that the pneumatic tired roller shall 28 be used between October 1 and F pril 1. Coverage's with 2 vibratory or steel i29 wheel roller may precede pneumatic tired rolling. When HMA Class D is being 30 constr�cted, the use of pneumatic rollers will not be reyuired. 31 E 31 Vibratory rollers shall not be operated in the vibralory mode when the internal 33 temperalure of the HMA is less than 175°F without permission of the Engineer. 34 In no case shall a vibralcry roller be operaleo in a vibratory mode when ' 35 checking or cracking of ttie mat occurs at a oreater temperature. Vibratory � 36 rollers in the vibratory mode are also prohibited on bridge decks. 37 1 38 5-04.3(10)B Contro! 39 �iMA Classes A, d, E, and F used in traffic lanes, including lanes for ramps, 40 truck climbing, weav�ng, and speed change, and having a specified compacted 41 course thickness greater than 0.10 foot, shall be compacted to a speci(ied level 42 i+f relative density. The specified level of relative density shall be a Composite 43 Pay Faclor (CPF) of not less than .75 when evaluated in accordance with 44 Section 1-06.2(1), using a minimum of 91.0 percent of the reference maximum 45 den�ity as dete�mined by WSDOT FOP for AASHTO T 209. The reference 4C m?ximum density shall be determined as the moving average of the most + 47 recent (ive determinalions for the lot of HMA being placed. The specified level 46 of density attained wiil be determined by the statistical evaluation of Tive nuclear � 49 densily gauge tesis tal:en in accordance with WAQTC FOP TM 8 and 50 WSDOT SOP T 729 on the day the HMA is placed (afler completion of the i Port ot Everett FAWAT-03-(139 Satel�ite Rai118arge Transfe�Facility Final Port Raview DraR �, Phase 7 Pier Constructlon 64 15 March 2005
