NOTE: This guide specification only applies to
geosynthetic (extensible) reinforcement. There are
differences in design and construction applicable to
steel soil (inextensible) reinforcement.
**************************************************************************
a. Blocks. Segmental concrete retaining wall units will be referred
to as blocks.
b. Drainage Aggregate. Granular soil or aggregate which is placed
within, between, and/or immediately behind segmental concrete units.
c. Fill. Soil or aggregate placed in, behind, or below the wall will
be referred to as fill.
d. Reinforced Fill. Soil which is placed and compacted within the
neat line volume of reinforcement as outlined on the plans.
e. Retained Fill.
Soil which is placed and compacted behind the
reinforced fill.
f. Reinforcement. Reinforcement shall consist of a geogrid or a
geotextile product manufactured for use as reinforcing. Reinforcement
shall not include steel products.
g.
Long Term Design Strength.
The long term design strength (LTDS) is:
LTDS = Tult / (RFD * RFID * RFCR)
where:
Tult is the ultimate strength
RFID is the reduction factor for installation damage
RFCR is the reduction factor for creep
1.3
SUBMITTALS
**************************************************************************
NOTE: Submittals must be limited to those necessary
for adequate quality control. The importance of an
item in the project should be one of the primary
factors in determining if a submittal for the item
should be required.
A "G" following a submittal item indicates that the
submittal requires Government approval. Some
submittals are already marked with a "G". Only
delete an existing "G" if the submittal item is not
complex and can be reviewed through the Contractor's
Quality Control system. Only add a "G" if the
submittal is sufficiently important or complex in
context of the project.
For submittals requiring Government approval on Army
projects, a code of up to three characters within
the submittal tags may be used following the "G"
designation to indicate the approving authority.
