- <br />Materials not meeting the specified moisture content and dry density requirements, as determined <br />by the tests, shall be reworked until approved results are obtained. Reworking may include <br />removal, rehandling, reconditioning, rerolling, or combinations of these procedures. The <br />Contractor shall be entitled to no additional allowance above the prices of the work required to <br />achieve the placement moisture content and density specified in this section. <br />The moisture content of the earthfill material prior to and during compaction shall be distributed <br />uniformly throughout each layer of the material. As far as practicable, the materials shall be <br />brought to the proper moisture content by adding supplementary water, if required, to the material <br />by sprinkling on the earthfill and each layer of earthfill shall be conditioned so that the moisture is <br />uniform throughout the layer. <br />Density control of compacted earthfill shall be such that the dry density of the compacted material, <br />as determined by tests performed by the Engineer, shall conform to not less than 90% of its <br />Proctor maximum dry density. Material which does not meet these requirements will be rejected <br />and shall be reworked until a dry density equal to or greater than these requirements is reached. <br />3.06 PLACING AND COMPACTING <br />A. Compacted Fill <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 placing <br />operations shall be such that the materials will be sufficiently blended to secure the best <br />practicable degree of compaction and stability. <br />The material shall be compacted to 90% of the Standard Proctor as described in ASTM D-698. The <br />method of compaction shall be submitted to [he Engineer for approval. <br />END OF SECTION <br />01/99 Section 02290 -Page 3 of 3 <br />
