The water shall not be drained into work completed or under construction without the consent of the <br />Engineer. <br />The dewatering operation shall continue until such time that it is safe to allow the water table to rise <br />' in the excavation and upon the approval by the Engineer. <br />3.03 STRIPPING -See Section 02100 -Site Preparation <br />3.04 PLACING EMBANKMENT MATERIALS <br /> The suitability of each part of the foundation for placing embankment materials thereon, and of all <br />1 materials for use in embankment construction, will be determined by the Engineer. No embankment <br /> material shall be placed in the fill area when either the material or the foundation or embankment on <br /> which it would be placed is frozen. <br /> No brush, roots, sod, or other perishable or unsuitable materials shall be placed in the embankment. <br />' Each load of the material placed in the embankment, whether from excavation for other parts of the <br />work or from borrow pits <br />shall be placed in the location designated by the Engineer <br /> , <br />. <br /> If, in the opinion of the Engineer, the surface of the prepared foundation or the compacted surface of <br /> any layer of earthfill is too dry or smooth to bond properly with the layer of material to be placed <br /> thereon, it shall be moistened and/or worked with harrow, scarifier, or other suitable equipment, in <br /> an approved manner to a sufficient depth to provide a satisfactory bonding surface before the next <br /> succeeding layer of earthfill material is placed. If in the opinion of the Engineer, the compacted <br />' surface of any layer of the earthfill in place is too wet for proper compaction of the layer of earthfill <br /> material to be placed thereon, it shall be removed; allowed to dry; or be worked with harrow; <br />' scarifier, or other suitable equipment to reduce the moisture content to the required amount; and <br />then it shall be recompacted before the next succeeding layer of earthfill material is placed. <br /> The earthfill on each side of any structures shall be kept at approximately the same level as the <br /> placing of the earthfill progresses, and the structures shall be protected against displacement or other <br /> damage. <br />' 3.05 MOISTURE AND DENSITY CONTROL <br />A. FIII Material <br />The standard optimum moisture content is defined as "that moisture content which will <br />result in a maximum dry unit weight of the soil when subjected to the Standard Proctor <br />Compaction Test as described by ASTM D-698." Material represented by the samples tested <br />having a placement moisture content less than 2% below standard optimum condition or <br />more than 3% wet of the standard optimum condition will be rejected and shall be reworked <br />until the moisture content is between these limits. Additional moisture as required in the <br />' opinion of the Engineer may be applied by sprinkling. <br />Each layer of the material on the embankment shall be compacted as Indicated in the section <br />which applies to the material being placed. During compaction, the placement moisture <br />content and dry density of the earthfill shall be maintained within the control limits specified <br />in each section. <br />' To determine that the moisture content and dry density requirements of the compacted <br />earthfill are being met, field and laboratory tests will be made at frequent intervals on <br />' 07/97 <br />Section 02290 -Page 2 of 3 <br />1 <br />
