The test pad <br /> was constructed to allow a minimum of 20 feet spacing between the west end of the test pad <br /> and the west slope crest of the secondary landfill. <br /> BORROW SOILS <br /> The borrow area was located south of the secondary landfill. The borrow area soils were <br /> classified as a red-brown silty sand (SM). Samples of the borrow soils were acquired by <br /> Kleinfelder prior to test pad construction for sieve analysis, with the following result. <br /> Borrow Soil Description -200 Sieve (Percent Passing) <br /> Red-Brown silty sand (SM) 34 <br /> Based on the sieve analysis and visual observations, SP/SM material was not present in the <br /> borrow area. The SM borrow soil was transported by scraper to the test pad where additional <br /> ANIL lab testing was performed. <br /> ST PAD CONFIGURATION <br /> The test pad was approximately 200 feet in length and approximately 100 feet wide. The long <br /> axis of the test pad was aligned in a north/south direction. Both the County and Teichert <br /> staked the test pad area. The eastern half of the test pad consisted of the "2-lift" construction, <br /> and the western half consisted of the "single-lift" construction pads. <br /> SITE PREPARATION <br /> Prior to construction of the test pad, the site was cleared of all brush, grass and any other <br /> organic matter which had grown subsequent to the completion of the foundation layer. <br /> Foundation material removed during the course of this procedure was replaced and the <br /> foundation layer was restored to its original final grade and surveyed by the County. The <br /> foundation layer was compacted to a minimum relative compaction of 90 percent (ASTM test <br /> method D-1557 "A"). <br /> TEST PAD CONSTRUCTION <br /> Approximately 13 to 14 inches of SM borrow materials were placed by Teichert on the test <br /> pad. Composite samples from two locations of the test pad were acquired for sieve analysis <br /> to verify visual classification. <br /> Test Pad Soil Description -200 Sieve (Percent Passing) <br /> Red Brown silty. sand (SM) 32 <br /> GSM:md 13/94 <br /> Copyright 1994 KLeinfelder, Inc.
