These are <br />noted as Soil Types 2 and 3 on the Summary Sheets, home lenses of a <br />lean clay were found. These are rather scattered however, and aaa <br />nOt be counted on over the entire site. Por the purposes o! <br />the site, the lean clays of Soil Type No. 4 or the very silty sands <br />of Soil Type &o. 3 will probably be the bast. Soil Type No. 2 aan <br />used haWever, and contains sufficient fines to allow good eanpaation <br />Ia general, Soil Type Ao. 1 is somewhat too coarse and contains insu <br />ficient fines for proper compaction on a land Lill use. Portunately,~ <br />moat of the soils on the land fill site are of either Soil Type• 2, <br />or 4. <br />All of these soils can ha easily compacted by <br />proper means. In general, the sancta of Soil Types 2 and 3 will be <br />compacted morseaeily and efficiently with a vibratory roller. A <br />6heep'a Foot may be used or the soil may simply be tread compacted, <br />since the required density is not extremely high. <br />Soil Type Ho, 1 is a well graded, silty sand of <br />coarse to medium grain size. This material is non-plastic, psrmeablc <br />and generally of medium 8ensity. It compacts easily under a vibrator <br />but not under a Sheep's Foot or wheal rolling. This Boil does not <br />contain sufficient binder to allow its use as a cover for the land fi <br />material. It is a good material for Pine aggregate of certain types ~ <br />and for some kinds of road base. This soil type therefore could ba <br />stockpiled and used for these purposes. This will De discussed in the <br />5 <br />
