UFGS 02 66 10 Test Fill
in accordance with ASTM D422 and ASTM D4318. A minimum of [5] [_____]
density and [5] [_____] moisture content tests shall be performed per lift.
3.3.2 Clay Barrier Layer Tests**************************************************************************
NOTE: Sealed double ring infiltrometer (SDRI) tests
can be used to determine the hydraulic conductivity
of the clay barrier layer. However, SDRI tests are
not commonly performed due to the cost and length of
time required to complete the test. SDRI tests
should not be performed on slopes greater than 3
percent. EPA/600/R-93/182 provides additional
information on double ring infiltrometer tests.
**************************************************************************The QC Inspector shall inspect the clay barrier layer during construction to verify material and placement methods are acceptable. A minimum of [5]
[_____], 75 mm 3 inch Shelby tube samples shall be taken from the completed clay layer at locations directed by the QC inspector. Shelby tube samples shall be extruded and visually examined by the QC inspector for signs of inadequate bonding between lifts. A set of classification tests and a hydraulic conductivity test shall be performed on each Shelby tube sample taken. Classification tests shall be performed in accordance with ASTM D422 and ASTM D4318. Hydraulic conductivity tests shall be performed in
accordance with ASTM D5084. A minimum of [5] [_____] field density tests and [5] [_____] moisture content tests shall be performed on each lift of clay placed.3.3.3 Geosynthetics Tests
**************************************************************************
NOTE: Geomembrane seam tests are sometimes
performed on test fills. If seam tests are going to
be performed, requirements for seam types and
locations should be specified. Vertical pipes are also sometimes placed in the test fill to simulate gas vents in the cover system. A geomembrane boot is then installed around the pipe. Delete this
paragraph if geomembrane seam tests will not be
performed.
**************************************************************************
[Three] [_____] sets of quality control and [3] [_____] sets of quality assurance shear and peel tests shall be performed on geomembrane seams at approved locations. All geomembrane seams shall be nondestructively tested for leaks. Seam tests shall be performed as specified in Section 02 56 13 WASTE CONTAINMENT GEOMEMBRANE.
3.3.4 Granular Drainage Layer Tests
**************************************************************************
NOTE: Granular drainage layer material is normally
not compacted for landfill applications. Therefore,
density tests are typically not required for a
granular drainage layer.
**************************************************************************
A minimum of [2] [_____] sets of classification tests shall be performed on
