PROJECT DESCRIPTION
The project concerns expressway R3, section Trstená by-pass in total
length of 9.8km on E77 transition route from Poland via Orava Region
down to the south.
The retaining walls were constructed as end of embankments at the
bridge earth fill supports for six bridges where they gradually turned
into sloping embankment wing walls with average heights ranging
between 4 and 14m.
Retaining walls exceeding height of 5m were designed as stepped.
The faces of the walls were vertical. Retaining walls under the bridge
structure were built on the bridge support foundations, while the wing
walls were constructed on their own strip foundations.

Contractor (Združenie Trstená R3) – acting on behalf of the main
contractor VÁHOSTAV – SK, a.s. Žilina was choosing between three
systems for the construction of reinforced earth structures and decided
to use a combination of mono-oriented Tenax geogrids and T-BLOCK
concrete blocks manufactured by VÁHOSTAV – SK – PREFA, s.r.o.
Horní Hriov. The geo-grids are anchored between two T-BLOCK units
with the use of T-Clips locks. The dimensions of the blocks were 1000
x 500 x 300mm.
