Geosynthetics are at the ready

eosynthetics play a varied and important role in infrastructure,
from liners and covers for reservoirs to landfill covers. They can
be found in highway construction and in coal ash impoundments.
They are part of the basic framework of public and private construction, supporting modern expectations for transportation, sanitation
and reliable energy.
The American Society of Civil Engineers (ASCE) gave American
infrastructure a D+ in its 2017 Infrastructure Report Card. As shown
in this issue, geosynthetics can play a significant role in the rebuilding
of infrastructure. It may be awhile before Washington moves toward
comprehensive infrastructure legislation, but things are moving on state
and local levels, and in private industry. Federal infrastructure legislation has become law on a relatively smaller scale, such as the recently
passed $19 billion disaster aid package, which includes funds to rebuild
infrastructure in areas of the country struck by storms.
In this issue, we take a final look at the Palos Verdes Reservoir liner
and cover, the fourth installment in the series of a geosynthetics project
in motion. Landfill gas collection and containment is the concern in our
second feature, a concern addressed by a minitube blanket, a type of
drainage geocomposite. Supporting poor soil beneath a major freeway
is the focus of "Stabilization of Subgrade Soils during Interstate 95 Lane
Widening," a problem addressed with geogrids. In the fourth feature,
closure of a coal ash impoundment is accomplished using a tufted
geosynthetic final cover system, a combination of a geomembrane and
engineered synthetic turf.
This is just a small sampling of the many infrastructure applications
geosynthetics can address. As federal legislation advances, geosynthetics are at the ready.
