capacity. Tabulated manufacturer's data is acceptable, if the
embedment soil conditions are applicable to the project site.
SD-04 Samples
Articulating Concrete Block
At the same time as the ACB and Geotextile Data submittal, the
Contractor shall submit two samples of the proposed block. The
samples shall be typical of the size, texture, color, and finish.
If the Contracting Officer is familiar with the product, this
submittal may be waived.
SD-06 Test Reports
Flume Test
At the same time as the ACB and Geotextile Data submittal, the
Contractor shall submit a report of testing for the ACB in
substantial conformance with FHWA RD-89-199. The report shall
clearly state if the critical shear stress associated with the
stability threshold of the ACB system was derived from laboratory
testing that included a sub-block drainage layer as a component of
the tested system.
1.4
SCHEDULE
To limit ultraviolet light exposure of the geotextile, the blocks shall
generally be placed within 7 days after placing the geotextile, and the
void filler shall generally be placed within 14 days after placing the
geotextile.
1.5
DELIVERY, STORAGE AND HANDLING
The Contractor shall check products upon delivery to assure that the proper
material has been received and is undamaged. For geosynthetics, the
guidelines presented in ASTM D 4873 shall be followed.
1.5.1
Blocks
All blocks shall be sound and free of defects that would interfere with
proper placement or that would impair the strength or longevity of the
installation. Blocks with the following defects shall be discarded:
a.
Blocks
with broken appendages.
b.
Blocks
with chips larger than 50 mm 2 inches in any dimension.
c.
Blocks
with cracks wider than 0.5 mm 0.02 inches and longer than
33%
of the
nominal height.
Minor cracks incidental to the usual method of manufacture, or chipping
that results from customary methods of handling in shipping, delivery and
placement will not be deemed grounds for rejection. Blocks shall be stored
in a suitable location away from mud, paint, wet cement, and other
contamination or disturbance.
