content of the material is reduced to an amount within the specified <br />limits. <br />d. The water contained in the earthfill material during compaction shall <br />be distributed uniformly throughout the layer of material being <br />compacted. The moisture content after compaction shall be as <br />uniform as practicable throughout anyone layer of the earthfill <br />material. The allowable ranges of Water content are based on design <br />considerations. <br />e. Material represented by the samples tested having a water content <br />outside the limits shown below will be rejected and shall be removed <br />or reworked until the water content is between these limits as <br />specified below. <br />Zone I Fill: Less than one (1) percent below optimum water <br />content and more than 3 (3) percent above optimum water <br />content. <br />2. Zone II Fill: Less than two (2) percent below optimum water <br />content and more than 2 (2) percent above optimum water <br />content. <br />3. Zone III Fill: No requirement <br />4. Topsoil: No requirement <br />3. Density Control: <br />a. Density control of compacted earthfill shall be such that the dry <br />density of the portion of the compacted material passing a United <br />States Standard No. 4 sieve as determined by tests performed by the <br />Engineer shall conform to the following limits: <br />1. Material represented by samples having a dry density less <br />than 98% of its laboratory maximum dry density will be <br />rejected as outlined below. Such rejected material shall be <br />rerolled or reworked as necessary until its dry density is <br />equal to or greater than 98% of its maximum dry density. <br />2. For all earthfill having a dry density greater than the above <br />limit and based on a continuous record of tests made by the <br />Engineer on previously compacted and accepted earthfill , <br />the uniformity of dry density shall be such that: <br />a. The average dry density of all accepted embankment <br />material and of material represented by any 10 <br />consecutive tests within a work area of the liner <br />embankment shall be not less than 98% of the <br />laboratory maximum dry density with no single test <br />sample being lower than 95% of the maximum dry <br />density. <br />NCCI Pit #1 Reservoir Liner - Technical Specifications Fill <br />312323 -9 <br />
