Construction of a road embankment

Construction of a railways embankment
|
A road or railway embankment is normally a large
structure, the construction of which always involves moving vast
amounts of soil normally of good quality.
It also causes considerable
inconvenience for the community, both in terms of land take and
for the environmental impact such a structure has.
The construction
of a viaduct or of a concrete structure represents a decidedly more
expensive alternative, even in terms of the structure’s environmental
impact.
To limit costs, it’s necessary to build road embankments having steeper slopes, or else to build them having the same shape
but using cheap or available on-site fill soil with poor mechanical
properties.
The utilization of TENAX TT geogrids allows for the construction
of steep slopes (up to 80°- 85° above horizontal), while
still guaranteeing full performances within the project designer’s
safety factor.
During project design, it’s possible to consider
all the stresses to which the road embankment will be subjected,
such as static and dynamic surcharge loads, or eventually, the ones
due to seismic activity, therefore guaranteeing the safety of the
structure.
Furthermore it is possible to utilize any type of soil
available on-site, allowing a considerable savings in terms of construction
costs.

A geogrid reinforced road embankment allows
to save 50% of the fill soil and 50% of the land
take (and even more) compared to a traditional
unreinforced one.

A geogrid reinforced steep slope allows to double
an existing railway line with minimal or
no additional space required.
