DRAFT <br />The water shall not be drained into work completed or under construction without the consent of the Engineer. <br />The dewatering operation shall continue until such time that it is safe to allow the water table to rise in the <br />excavation and upon [he 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 embanlmtent materials thereon, and of all materials for <br />use in embanlanent construction, will be detemtined by the Engineer. No embankment material shall be placed <br />in the fill area when either the material or the foundation or embanlanent on 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 embatilmtent, whether from excavation for other parts of the work or <br />from borrow pits, shall be placed in the location designated by the Engineer. <br />If, in the opinion of the Engineer, the surface of the prepared foundation oz the compacted surface of any layer <br />of ear[hfill is too dry or smooth to bond properly with the layer of material to be placed thereon, it shall be <br />moistened and/or worked with harrow, scarifier, or other suitable equipment, in an approved manner to a <br />sufficient depth [o provide a satisfactory bonding swface before the next succeeding layer of earthfill material <br />is placed. If in the opinion of the Engineer, [he compacted swface of any layer of the earthfill in place is too <br />wet for proper compaction of the layer of earthfill material to be placed thereon, it shall be removed; allowed to <br />dry; or be worked with harrow; scarifier, or other suitable equipment to reduce the moisture content to the <br />required amount; and then it shall be recompacted before the next succeeding layer of earthfill material is <br />placed. <br />The earthfill on each side of any structwes shall be kept at approximately the same level as the placing of the <br />earthfill progresses, and the stmctwes shall be protected against displacement or other damage. <br />3.05 MOISTURE AND DENSITY CONTROL <br />A. Fill Material <br />The standard optimum moisture content is defined as "that moisture content which will result in a <br />maximum dry unit weight of the soil when subjected to the Standard Proctor Compaction Test as <br />described by ASTM D-698." Material represented by the samples tested having a placement moistwe <br />content less than 2% below standard optimum condition or more than 3% wet of the standard optimum <br />condition will be rejected and shall be reworked until the moismre content is between these limits. <br />Additional moisture as required in the opinion of the Engineer maybe applied by sprinkling. <br /> <br />
