<br />1.2 <br />development to allow time for representative testing without unduly <br />interrupting construction activities. Should the material prove to <br />be unsuitable, such material shall not be used. <br />Representative tests shall be conducted for every 10,000 cu <br />yds of material used as fill, or when a change in material occurs <br />within the borrow area or stockpile. Representative tests for <br />granular material shall be run for every 5,000 cu yds of material <br />taken from borrow pits or stockpiles and used as fill. <br />Construction Testino Schedule <br />During construction, the following schedule will be used for <br />conducting Construction Control Tests on each of the materials placed <br />during a work shift. <br />Number of Tests Quantity of Material Placed <br />1 test minimum Less than 2,500 cu yds <br />2 tests minimum 2,500 to 5,000 cu yds <br />1 tests/2,500 cu yd Greater than 5,000 cu yds <br />Tests may be conducted more frequently at the direction of the <br />Engineer or the Engineer's representative. Such testing will be done <br />when indicated as necessary by the following guidelines: <br />1) Areas where special compaction equipment or methods are <br />used. <br />2) Areas where the height of fill rises quickly versus the <br />quantity of fill placed. <br />3) Areas where compaction control is particularly important <br />such as around appurtenant structures. <br />4) Areas where the required compaction may noh have been <br />achieved based upon visual observations. <br />5) Areas where unacceptable material may have been placed. <br />6) Spot checks as required by the representative of a <br />regulatory agency. <br />
