Chemical Analysis: Perform chemical analysis in accordance with the approved
Sampling and Analysis Plan (SAP).
Confkrnation Sampling: Collect confirmation soil samples from the ‘excavation
bottom and sidewalls in accordance with the SAP.
Soil Tests: For each loose lift, take representative samples from both the foundation
layer and the vegetative layer for testing at the frequencies listed in Table 02200-1,
EARTHWORK TESTING REQUIREMENTS.
Moisture Content and Density Tests: Perform moisture content and density tests in
a grid pattern on the upper foundation layer and the vegetative layer. Stagger the grid
pattern for successive lifts so that sampling points are not at the same location in each
lift. Moisture content and density tests will be performed in accordance with
Table 02200- 1, EARTHWORK TESTING REQUIREMENTS. Observe and
visually classify in accordance with ASTM D2488 with notes recorded on the daily
inspection reports.
Weather Conditions: Do not place or compact general fill, foundation layer material,
or vegetative cover during adverse weather conditions.
Excess Surface Water: Remove excess surface water before placement of additional
general fill, foundation layer, or vegetative cover. Kin-place material is reworked and
recompacted, compact affected areas in the same manner as the rest of the area.
Repair and reestablished grades darnaged by erosion before acceptance of the work.
Subgrade Fill: During construction keep subgrade fill and excavations shaped and
drained. Maintain ditches and drains along subgrade in a manner that permits
drainage of water. Do not disturb the finished subgrade by traffic or other operations
and protect and maintain in a satisfactory condition until base course or pavement is
placed. The storage or stockpiling of materials on the finished subgrade will not be
permitted. No base course, or pavement will be laid until the subgrade has been
checked and approved. Do not place base course
subgrade.
