BOEING EVERETT SECTION 34 11 11 <br /> NEW RAIL SPUR BALLASTED TRACK CONSTRUCTION <br /> WORK ORDER 10-305 <br /> 3] SURFACING AND AUGNING <br /> A After the skeleton track has been inslalled, p�ace ballast i;.the tie cribs and shoulders of the track <br /> structure to restrain movement of ihe ties due to temperature changes in lhe CWR. Unload ballast <br /> in suNicient quantities lhal wiil form a high shuulder and will fill the lie cribs and provide an adequale <br /> amount oi ballast for the initial lreck lift,plus a surplus as required to continue lo hold the track in <br /> Ilne after lhe initial track lifl. <br /> B Track surfacing shall be by melhods lhat will prevent undue bending of the rail, slraioing oi the <br /> joints, and damaging or loosening the spnng clip fastenings. The amounl of Irack hR shall neither <br /> exceed 4 inches nor endanger the honzontal and veAical slability of lhe lrack. The track shall be <br /> raised so thal a final lift shall not be less lhan 1 inch or more than 3 inches when bringing the lrack <br /> to the final suAace.Complele(ina�suAacing and aligning ol lhe lrack aNer the track has been initiaily <br /> surlaced and aiigned,tastened, and joined logether by specified method <br /> C Have restraining rail in place tor final tampmg, suAacing and lining operation. <br /> D A%er the track has been finally raised, Imed and suAaced,the reils shall be refastened withm the <br /> specitied zerothermal stress temperature range. Clips shall be lhoroughly cleaned ol dust,dirt,and <br /> grindings prior to retaslening of rail Ties and (aslening devices damaged during the suAacing <br /> operetion shall be replaced with new ties and lastening devices at no addilional cosl to the Owner. <br /> E. The final raising and aligning operations shell fill cribs and shoulders with ballasl lo wilhin 1 inch <br /> below the base oi rail. Provide a minimum ot 1-inch clearance between metallic portions ot the lrack <br /> structure end ballast. <br /> F. Discontinue suAacing when the ambient lemperalure is higher lhan 95 degrees F or the rail <br /> temperature exceeds 100 degrees F <br /> G Perlortn tamping with a squeeze-vibratory type power tampec Conlrol of the power tamper's <br /> tamping cyc�e shall ensure the mazimum undorm compaction of ballasl around the track Uniformly <br /> tamp ballasl under bolh sides of each lie,directly under each running rail tor a dislance oi 1 B inches <br /> on both sides of the raiL Tamping will not be permitled at the center ot the tie,but fill the cnbs with <br /> ballast For each tie,proceed wlth tamping simultaneously inside and outside both running rails on <br /> both sides of the tie. MechaNcally tamp the total treck length including transition slab area track <br /> zones. <br /> H Compact ballast shoulders wdh a vibretory shoulder compactor. Continue compacting unlil the <br /> ballast is firmly interlocked and lhe surface is true and unyielding, displaying no delormalion or <br /> movement under the compacGon eqwpment drainage lines, inlets, and underground ulilities <br /> conduits from damage during tamping and compacting. <br /> I Afler the fmal suriacing and Iming oi lrack has been completed,dress the ballast to coniorm to the <br /> ballast seclrons indicated on the Contract Drawings Reslope subballast outside lhe toe of slope oi <br /> ballast lhal has been fouled or disturbed by the Contracror's operaUons to lhe indicated cross <br /> secfions on tha Contract Drawings <br /> J The f�nal suAace and alignment of track shall be within the ballasted track installation tolerances <br /> specdied m Section 34 11 10.
