tested having a placement moisture content less than 2% below standard optimum <br />condition or more than 3% wet of the standard optimum condition will be rejected 2nd <br />shall be reworked until the moisture content is between these limits. Additional moisture <br />as required in the opinion of the Engineer may be applied by sprinkling and mixing of <br />wetted soils. <br />Each layer of the material on the embankment shall be compacted as indicated in the <br />section which applies to the material being placed. During compaction, the placement <br />moisture content and dry density of the earthfill shall be maintained within the control <br />limits specified 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 />samples taken at embanlanent locations determined by the Engineer. The results of all <br />completed earthwork tests will be available to the Contractor at the office of the <br />Engineer. <br />Materials not meeting the specified moisture content and dry density requirements, as <br />determined by the tests, shall be reworked unfit approved results are obtained. <br />Reworking may include removal, rehandling, reconditioning, rerolling, or combinations <br />of these procedures. The Contractor shall be entitled to no additional allowance above <br />the prices of the work required to achieve the placement moisture content and density <br />specified in this section. <br />The moisture content of the earthfill material prior to and during compaction shall be <br />distributed uniformly throughout each layer of the material. As far as practicable, the <br />materials shall be brought to the proper moisture content by adding supplementary water, <br />if required, to the material by sprinkling on the earthfill and each layer of earthfill shall <br />be conditioned so that the moisture is uniform throughout the layer. <br />Density control of compacted earthfill shall be such that the dry density of the compacted <br />material, as determined by tests performed by the Engineer, shall conform to not less than <br />95% of its Standard Proctor maximum dry density. Material which does not meet these <br />requirements will be rejected and shall be reworked until a dry density equal to or greater <br />than these requirements is reached. <br />3.06 PLACING AND COMPACTING <br />A. Compacted Fil] <br />The material shall be placed in areas shown on the Plans in continuous and approximately <br />horizontal layers, not more than 12- inch loose lifts. The combined excavation and <br />placing operations shall be such that the materials will be sufficiently blended to secure <br />the best practicable degree of compaction and stability. <br />The material shall be compacted to 95% of the Standard Proctor as described in ASTM <br />D-698. The method of compaction shall be submitted to the Engineer for approval. <br />END OF SECTION <br />Drafr -Technical Specifications <br />01/99 Section 02290 -Page 3 of 3 <br />
