Reid Middlctnn & Assuci;��es <br /> Seplemher 2. I992 <br /> r:,s� r, <br /> 5, The liner ma�erial should be placul in relxtively thin lilis (8 to 10 inches louxe thickness) <br /> and compacted to at least 95 percent of the maximum dry density determined in accordance <br /> with the ASTM D-1557 tect proceclure. At the time of compactian, the moisture comem <br /> of the liner material should be adjusteci to the op�imum value or to wi�hin 2 percent ahcrve <br /> this value. <br /> Soils to he useAl as pond lining material will be very sensitive to moisture. The moiswrc <br /> cuntent of this material will need to be as recommended in order to achieve the recommendal <br /> compaction. I� is generally ��x ��,ss�ni� u, a�n���� the recommendecl compaction if work is <br /> nttempted during wet weather or wiU: excessively wet soil. Therefore, the pond lining should <br /> be inslallai during extended periods of dr� weather. <br /> We recommend that GcviBngineen he ret.iinul to assist in identifying the upper extem of <br /> the existing liner prior �o pond ezpansiun ac(ivitics.
