Tests <br /> The Contractor is responsible for quality control and shall perform sufficient testing to <br /> ensure compliance with these specifications. Test results shall be submitted to the <br /> Construction Manager. The Construction Manager may take samples and perform moisture <br /> content, compaction, and density tests during placement of backfill materials to spot-check <br /> compliance with these specifications. The Contractor shall remove surface material at <br /> locations designated by the Construction Manager and provide such assistance as necessary <br /> for sampling and testing. The Construction Manager may direct the Contractor to construct <br /> inspection trenches in compacted or consolidated backfill to determine that the Contractor <br /> has complied with these specifications. <br /> Tests undertaken by the Contractor shall be in accordance with the following: <br /> Moisture content ASTM D3017 <br /> Density in-place ASTM D1556 or ASTM D2922 <br /> Moisture-density relationships ASTM D1557 <br /> 1.03 SUBMITTALS <br /> The Contractor shall submit information in accordance with Special Provisions Section <br /> SP-08, SUBMITTALS, to substantiate compliance with this specification.

Compaction <br /> The process of mechanically stabilizing a material by increasing its density at a controlled <br /> moisture condition. "Degree of Compaction" is expressed as a percentage of the maximum <br /> density obtained by the test procedure described in ASTM D1557 for general soil types <br /> abbreviated in this specification as "90% ASTM D1557 maximum density". <br /> Walnut Grove Sewer Project(Conformed) 02210-2 SA0160401 <br /> March 2008 n:\sa0160401\specs\wg conform\div 2\02210.doc <br />
