Geosynthetics August/September 2020 - 43
proposed action is potentially a worthwhile investment and should be further evaluated as a realistic opportunity,
compared against other alternatives
with similar B/C ratios.
Engineers are often consulted in
quantifying technical matters on both
sides of the B/C ratio; being asked to
predict the service life of a geosynthetic
in various environmental, transportation, hydraulic or geotechnical applications is commonplace. Regular discussions around service life of exposed
versus buried geosynthetics are common in the industry. It is refreshing to
hear project managers acknowledge
that plastics undergo first-, secondand third-order degradation mechanisms over time. We now have educated
customers in our industry. Important
questions are being asked: How long
will it last? When will this need to be
repaired or replaced? What environmental conditions (temperature, elevation, exposure orientation, latitude and
longitude) can be controlled to protect
this infrastructure?
It is freely admitted that the focus
of this discussion over the past 30 years
has been general in nature. Engineers
typically looked at worst-case scenarios
and concentrated on a few key parameters of the geosynthetics to make gross
estimates (i.e., a few years, 10-30 years,
more than 100 years) of service life.
Such gross estimates make it difficult
for project managers to produce effective B/C analyses due to the huge variability that each of those ranges contain.
However, I believe that it is time for our
industry to become more transparent
about the key indicator properties for
durability-challenged geosynthetics.

DON'T LANDFILL USABLE GEOTEXTILES!
We deal in used, surplus, or salvaged
geotextiles and building materials. AND, as
America's largest "industrial thrift store,"
we're also interested in anything obsolete...
Materials, Equipment, Inventory, or Machinery,
etc. that could be re-used/"repurposed"
anywhere in the US.
