UFGS 02 66 10 Test Fill
fill to anchor the [geomembrane,] [geosynthetic drainage layer,] [geotextile,] and [_____]. The anchor trench shall be a minimum of [450]
[_____] mm [18] [_____] inches wide and [600] [_____] mm [24] [_____] inches deep. The anchor trench shall be backfilled and compacted as specified in Section [31 00 00 EARTHWORK] [_____].
3.2.5 Test Fill Placement
All components of the test fill shall be constructed as described in the specification sections previously referenced. Geosynthetics shall extend a minimum of [300] [_____] mm [12] [_____] inches beyond the edge of the overlying layer.
3.2.6 Survey Control Points
**************************************************************************
NOTE: Control points should be shown on plan and
section views of the test fill. Permanent marks
should be placed on each geosynthetic layer which will be surveyed.
**************************************************************************The location of survey control points shall be as shown on the drawings. For soil layers, survey control points shall consist of 450 mm 18 inch steel pins. The steel pins shall be installed so as to not damage
underlying geosynthetics. Three straight rows of control points shall be placed horizontally across the test fill. The rows shall be parallel to the top and bottom edges of the test fill. Each row shall consist of the following:
a. Steel pins placed outside of the test fill, [3] [_____] meters [10]
[_____] feet away from each side.b. Steel pins placed in the select fill layer, [3] [_____] meters [10]
[_____] feet from the outside edge of the select fill layer on both sides of the test fill.
c. Permanent marks on the upper surface of each geosynthetic layer, on both sides of the test fill.
3.2.7 Permanent Bench Mark
Surveys shall be tied to a permanent bench mark outside the boundaries of the landfill.
3.3 TESTSEach layer of the test fill shall be tested as specified below. For random fill, clay barrier layer, and select fill layers, rapid methods may be used to perform moisture and density tests in accordance with ASTM D6938, or ASTM D4643. However, at least [1] [_____] density test per lift shall be performed using the methods described in ASTM D1556 or ASTM D2167 and at least [1] [_____] moisture content test per lift shall be performed using the methods described in ASTM D2216.
3.3.1 Random Fill Tests
A minimum of [2] [_____] sets of classification tests shall be performed on each lift of random fill placed. Classification tests shall be performed
