Prepare areas to be excavated or wheit,e.mbankment is to be constructed in with Section 02100. accordance i City of Fayetteville Page 02220-2 • • i 12/22/96 ' 3.2 EXAMINATION DURING CONSTRUCTION A. As excavation, embankment, and trenching work proceeds, examine the work area for evidence of prehistoric people's dwelling sites or artifacts of historical or archeological I significance. If any of these are encountered, suspend construction in the affected area until Owner or Engineer contacts archeological authorities to determine the disposition thereof. 3.3 GENERAL CONSTRUCTION REQUIREMENTS ' A. Excavation and embankments shall be finished to reasonably smooth and uniform surfaces according to the lines, grades, thicknesses and typical cross sections indicated on the Drawings. B. - Do not waste materials unless they are unsuitable for construction of embankments and they exceed the amount that can be spread on cut or embankment slopes. C. Common excavation materials that are surplus to the needs of the project shall be stockpiled at locations indicated on the Drawings or as directed by Engineer. D. Complete site preparation work in accordance with Section 02100 prior to beginning L excavation and embankment work. E. Conduct grading operations, as far as practicable, so that the most suitable soil is placed 1 in the top layer of the embankment. Where both suitable and unsuitable materials are encountered in the same general excavation area, control grading to keep materials separated. F. Exercise care and discretion in locating and using haul lanes near trees to be preserved. Haul lanes near trees shall be approved by Engineer. 3.4 ROADWAY EXCAVATION A. Excavate cut areas to approximate subgrade elevations to reasonably smooth and uniform surfaces in accordance with the lines and grades indicated on the Drawings. I B. Use suitable materials, so far as practicable, in the formation of embankments, in the subgrade, on slopes, and at other such places indicated by Engineer. ' C. Excavated material to be used in embankments shall be immediately placed in the embankment area so as to avoid stockpiling and double handling. I 1 City of Fayetteville Page 02220-3 , 1 • • 12/22/96 D. Where excavation to the finished grade section results in a subgrade or slopes of unsuitable material, remove the unsuitable material and backfill with approved material, such as select material "hillside" or any acceptable material from common excavation. E. Place material unsuitable for embankment construction on slo locations designated by Engineer. pes hauled off site, or other iF. Remove rock with suitable rippers. Blasting will not be permitted. ' G. Excavate rock to a minimum depth of 8 inches below subgrade elevation, not to exceed a maximum depth of 12 inches below subgrade elevation within the limits of the roadbed, including sidewalks, and the excavation backfilled with material designated on the Drawings. Take care that un-drained pockets shall not be left in the surface of the rock. H. Remove or stabilize, to the Engineer's satisfaction, rock on the cut face that is loose, hanging, or that creates a potentially dangerous situation during or upon completion of excavation in each lift. Ripping of the next lift will not be allowed until this work has been ' completed. I. Except in solid rock, trim all slopes to the slopes shown in the cross section drawings, and exercise care so that no material shall be loosened below the required slopes. Remove or cut roots, stumps, and other foreign matter in the sides of ditches or drainage outlets to conform to the slope, grade, and shape of the section shown. 3.5 EMBANKMENT CONSTRUCTION A. Embankment construction consists of constructing roadway embankments, including preparation of the areas upon which they are to be placed; construction of dikes within or outside the right-of-way; placing and compacting approved material within roadway areas where unsuitable material has been removed; and placing and compacting embankment material in holes, pits, and other depressions within the roadway area. Use only approved materials in construction of embankments and backfills. B. Remove sod and ve getable matter from the surface upon which embankment is to be constructed in accordance with Section 02100. Completely break up cleared surface by plowing, scarifying, or disking to a minimum depth of 6 inches, and then recompact as specified in Paragraph 3.6.C. C. Whenever a compacted road surface containing asphalt or granular material lies 3 feet of the subgrade, scarify old road surface to a depth of at least 8 inches. Recompact this scarified material to a stable condition. D. Place roadway embankment material-in parallel layers not exceeding 8 inches, loose City of Fayetteville Page 02220-4 • • 1 12/22/96 I measurement, over the full width of the embankment and compact as specified before the next layer is placed. Use effective spreading equipment on each lift to obtain uniform thickness prior to compacting. As compaction of each layer progresses, continuously level and manipulate material to assure uniform density. Add water or dry, if necessary, in order to obtain the required density. Route compaction equipment uniformly over the entire surface of each layer. E. When embankment is to be placed and compacted on hillsides, continuously bench slopes as the work is brought up in layers. Make benching of sufficient width to permit operations of placing and compacting equipment. Start each horizontal cut at the intersection of the original ground and the vertical sides of the previous cuts. Recompact material thus cut out. No additional payment will be made for this. F. When excavated material consists predominantly of rock fragments of such size that the material cannot be placed in layers of the thickness specified, place such material in the embankment in layers not exceeding in thickness the approximate size of larger rocks, up to 12 inches maximum. Reduce size of rock or boulders too large to permit placing in 12 inch layers as necessary to permit this placement. The 12 inches of embankment immediately below fir.ished subgrade may be placed in one layer with no rock exceeding 6 inches in its greatest dimension. Construct each layer so that rock voids are substantially filled with rock fines and earth. Place and manipulate rock in uniform layers with rock fines or earth distributed throughout the layer. Do not end dump rock over the edges of the layer being constructed. Deposit rock on the layer being constructed and move the rock ahead so as to advance the layer with a mixture of rock fines and earth. G. Casting material directly into place with draglines, cableways, or other similar machines will not be permitted. H. Control embankment construction so that partially constructed embankments remain stable at all times. Replace portions that have become displaced due to carelessness or negligent work; no extra payment will be made for such embankment repair. I. For those portions of embankments immediately adjacent to structures or which are for , other reasons inaccessible to compaction equipment in use, construct with only suitable material in successive parallel layers of not more than 6 inches thickness, loose measurement. Uniformly mix each layer and compact to the requirement of the specific item by the use of mechanical equipment. Hand tamping will not be permitted. ins of not less than 200 feet in length,Construct embankments in sections or the full length of the embankment if less than 200 feet. 3.6 COMPACTION REQUIREMENTS City of Fayetteville Page 02220-5 ' • • ' 12/22/96 A. Accomplish compaction by any satisfactory method or methods that will achieve the specified density. B. Maintain compaction equipment, tools, and machinery in good operating condition. C. Compact each layer of embankment to 95 percent of maximum density at optimum ' moisture content per AASHTO T 99, with correction for coarse particles retained on the #4 sieve not to exceed 30 percent by weight as determined by AASHTO T 224. If more than 30 percent by weight of embankment material is retained on the #4 sieve, compact ' to 95 percent of maximum density at optimum moisture content per AASHTO T 180. Specified density of 90 percent with the same previous conditions is required immediately next to wingwalls and similar structures. ' D. During compaction maintain , moisture content substantially at optimum throughout each layer. Maintain moisture content by adding and thoroughly mixing water or by aeration 1 or other drying methods, as necessary. E. Maintain specified density of embankment layer prior to placing a subsequent layer. F. Construct embankment to grade over the full width in uniform layers parallel to the ' finished surface. G. Density requirements will not apply to portions of embankment constructed of material so rocky that it cannot be satisfactorily tested as specified. In such cases, determine extent of compaction effort by rolling based upon the amount of breakage and consolidation that can be accomplished. This can only be done with the direction of the Engineer.

The tests sal pass the minumum requirements of these specifications. - City of Fayettevil le Page 02520-6 , • 1 12/18/96 IB. The concrete shall be deposited on the base in such manner to prevent damage to the base material and to require as little re-handling as possible. g IC. Mechanical Methods - After the concrete has been deposited ands r eit shall b consolidated by means of a mechanical vibrating machine f approved type and design. IThe pavement shall be vibrated with equipment recommended for the type of slab lay down process the Contractor uses. Vibration shall extend over the entire pavement area and the vibrating machine shall satisfactorily consolidate the mixes required for this type Iof construction and shall not displace the side forms,joints, or dowel bar assemblies. The concrete shall be deposited, spread, and vibrated in a manner that will insure minimum segregation and develop a maximum density and strength in the finished I pavement. After vibratory consolidation, the concrete shall be struck off by means of an approved power driven, mechanical finishing machine to the lines and grades indicated in the typical section and the Drawings. I Slip Form Paver- The slip form paver shall be designed to spread, consolidate, screed, I and finish the freshly placed concrete in one complete pass of the machine in such manner that a minimum of hand finishing will be necessary to provide a dense and homogeneous pavement in conformance with the Drawings and specifications. The paver shall be self- I propelled. The machine shall vibrate the concrete for the full width and depth of pavement being placed. This vibration shall be accomplished by means of satisfactory internal vibration in the course of concrete placed. The sliding forms shall be rigidly held ill together laterally to prevent spreading of the forms. Hand finishing shall be kept to a minimum. If the machine is of the trailing form type, and hand finishing is required, it must be done within the length of the trailing forms. The slip form paver shall be operated with a cont inuous forward movement and all operations of mixing, delivery, and spreading concrete shall be so coordinated as to I provide a uniform progress with stopping and starting of the paver held to a minimum. If for any reason, it is necessary to stop the forward movement of the paver, the vibratory and tamping elements shall also be stopped immediately. No tractive force shall be I applied to the machine except that which is controlled from the machine. D. After the concrete has been struck off and consolidated, it shall be further smoothed and I consolidated by any approved method of mechanical floating which will satisfactorily finish the pavement to the required cross-section, elevation, and surface smoothness. Excess water, laitance, or foreign materials brought to the surface during the course of the floating operations shall not be reworked into the pavement but shall be removed immediately upon appearance by means of a squeegee or straightedge drawn from the center of the pavement toward either edge. In general, the additional water to the surface of the-Concrete to assist in firiliing operations will not be permitted., if allowed, it shall be applied as a fog spray by means of approved spray equipment. • City of Fayetteville Page 02520-7 Ill 12/18/96 1 E. After the longitudinal floating has been completed, but while the concrete is still plastic, I the slab surface shall be checked by the Contractor in both directions for trueness, using a straightedge. For this purpose an accurate 10' metal straightedge shall be used, swung I from a handle longer than one-half the width of the slab. Additional floating may be necessary to eliminate all irregularities. The straightedge shall be held in successive positions paralled to the pavement centerline in contact with the surface and the surface checked for the full width of the slab. Progression along the pavement shall be in successive stages of not more than one-half the length of the straightedge. Depressions found shall be immediately filled with freshly mixed concrete, struck-off, floated, and I refinished. High areas shall be cut down and refinished. Straightedge testing and surface correction shall continue until the entire surface conforms to the required grade and section. The surface deviation tolerance shall be 1/8" +1-• Any surface with a deviation anon I exceeding this tolerance shall be corrected by grinding. Any pavement dg +/- surface deviation may be removed at the discretion of the Engineer. Any cost of correction to surface deviations shall be borne by the Contractor. I F. Following the straightedging and after all excess moisture has disappeared, the surface I of the concrete pavement shall be given a final finish with a drag followed by tining. The tining grooves produced in the concrete shall be from 1/8" to 3/16" in depth. These grooves shall be transverse to the centerline of the pavement. G. Longitudnal and transverse joints,where required, shall be so constructed as to allow the normal finishing operations to be executed and completed over the joint. After the final I finish,but before the concrete has taken its initial set, the edges of the pavement along each side of the slab, and on each side of transverse expansion joints and formed joints, shall be worked with a 1/2" radius edger. Any edge marks produced shall be removed I by floating and brooming that area. Concrete on top of joint filler shall be completely removed. Joints shall be tested with a straightedge before concrete has set. Corrections shall be made if one side of the joint is higher or lower than the other. I H. Immediately after finishing operations have been completed and as soon as marring of the concrete will not occur, the entire surface on the concrete shall be cured with either I polyethlene-burlaP mats or membrane curing. Either product shall be listed in the AHTD Qualified Products List and shall be applied according to the manufactuer's I recommendations and in accordance with the AHTD Standard Specifications. I. All traffic shall be excluded from newly constructed pavement by the Contractor until the concrete is found, by suitable tests of representative cylinders prepared at regular intervals and subjected to the same curing conditions as the pavement, to have a compressive strength of not less than 80% of the minimum compressive strength specified. The pavement shall not be ojiened to traffic in less than 7 days, except that the minimum time for opening the pavement to traffic shall be reduced if the Contractor chooses to use a high early strength concrete that meets or exceeds the mix design. The I Page 02520-8 1 City of Fayetteville 1 • • I12/22/96 time of opening will be dictated by the same type of test of the cylinders when the compressive strength is not less than 80% of the minimum compressive strength 11specified.

SS-S-200, hot applied joint sealant ASTM D-3406 or ASTM D-3405, or one part silicone formulation that does not require a primer for bond to concrete. These sealants Iwill form an effective seal against water and be incompressible. Hot applied sealant shall not be used on integral curb or curb and gutter. Traffic should not be allowed until sealant has cured sufficiently to prevent damage to sealant. Immediately before sealing, I the joints shall be thoroughly cleaned of all laitance, curing compound, and other foreign material. Cleaning shall be accomplished by sandblasting. Upon completion of cleaning the joints, they shall be blown out with compressed air using a compressor that will I maintain the compressed air system free of oil and water. Transverse construction joints shall be constructed when there is an interruption in the concrete operation of more than 30 minutes.

Provide all pumps or other equipment necessary to maintain the test pressure within 5 psi at the test point for a period of two hours. Fire hydrant valves shall be open during the pressure test. ' B. Leakage 1. The leakage test shall be conducted concurrently with the pressure test. Leakage is defined as the quantity of water that must be supplied into the newly laid pipeline, or any valved section thereof, to maintain pressure within 5 psi of the specified test pressure after the air in the pipeline has been expelled and the pipeline has been filled with water. Leakage shall not be measured by a drop in pressure in a test section over a period of time. No pipeline installation will be accepted if the leakage is greater than that determined by the following formula: 1 1 City of Fayetteville Page 02675-2 • ' • 1 12/11/96 SD5' 133200 1 L= allowable leakage, (gallons per hour) S = length of pipe tested, (feet) D = nominal diameter of pipe, (inches) P = average test pressure during test, (psig) ' 2. If the leakage is greater than specified above, locate and make repairs as necessary until leakage is within specified allowance, without additional cost to Owner. 3. Repair visible leaks regardless of the amount of leakage. 3.5 DISINFECTION A. After successful pressure testing, the lines shall be flushed with a velocity equal to or greater than 2'/z fps. The line shall then be disinfected in accordance with AWWA C651, continuous feed method, except that the placing of hypochlorite granules into the main during construction will not be permitted. B. Pipes are to be disinfected after laying is completed by holding a chlorine solution of at least 50 ppm strength in the pipe for 24 hours. At the end of the 24 hour period, the treated water shall contain no less than 25 ppm of chlorine throughout the length of the main. C. As the heavily chlorinated water flows past fittings and valves, related valves and hydrants shall be operated so as to disinfect new appurtenances and pipe branches. Take extreme care to prevent heavily chlorinated water from flowing back into water mains in active service. Take care to ensure that discharge of flushing water shall not adversely affect any downstream properties. The disinfecting water shall be diluted or otherwise have the chlorine concentration diluted in a manner approved by Engineer. The cost of the chemicals shall be borne by Contractor. D. After the lines have been disinfected, they shall be thoroughly flushed until chlorine , residual measurements show that the concentration in the water leaving the main is no higher than that generally prevailing in the system or is acceptable for domestic use, or less than 1 ppm. Disposal of flushing water shall be as described above and as provided by applicable Laws and Regulations. Procure a special permit from the Arkansas Department of Pollution Control&Ecology to discharge the solution and water used in the disinfection of the pipes. - E. Bacteriological samples shall then be collected from each respective section of the new main on two consecutive days and shall be submitted to the Arkansas Department of City of Fayetteville Page 02675-3 1 • • 12/11/96 ' Health for analysis.
