Project No. D-3885-06 <br />Christ Our Savior Catholic Parish <br />| .4 Degree of Fill Compaction <br />The degree to which fill is to be compacted is expressed in terms of "relative <br />compaction.'r Relative compaction is defined as the ratio; expressed in percent, of the <br />in-place dry densiry of the compacted fill to the reference maximum dry density. The <br />reference maximum dry density shall be obtained following ASTM DI557. Optimum <br />water content shall be obtained in the same test used to obtain the relerence maximum dry <br />density. Conection of the maximum dry density and optirnum water content for oversize <br />particles of gravel and cobbles shall be made following ASTM D4718 when, in the <br />opinion of the Geotechnical Engineer, such correction is appropriate. The in-place density <br />shall be obtained following ASTM DI556 (sand cone method) or ASTM D2922 (nuclear <br />method-shallow depth) test method. The in-place water content shall be obtained <br />following ASTM D4944 (calcium carbide gas pressure meter), ASTM D3017 (nuclear <br />method-shallow depth), or ASTM D2216 (oven drying). Correction of the in-place <br />density and water content for oversize particles of gravel and cobbles shall be made <br />following ASTM D471 8 when, in the opinion of the Geotechnical Engineer, such <br />correction is appropriate. <br />If any of the test methods specified in this section are judged by the Geotechnical <br />Engineer to be impractical or unreliable because the material has a coarse particle size <br />distribution, or for other reasons, the Geotechnical Engineer shall establish other <br />procedures to obtain the required soil characteristics. <br />2.0 Products <br />2.1 Materials <br />2.1.1 General - During grading operations, soil types other than those identified in <br />the geotechnical investigation report may be encountered by the Contractor. Consult the <br />Geotechnical Consultant for his evaluation of the suitability of using these soils a fill <br />material prior to placernent or disposal. <br />60 <br />I <br />t <br />T <br />I <br />I <br />I <br />t <br />t <br />T <br />I <br />t <br />T <br />T <br />I <br />T <br />T <br />t <br />I <br />T
