kN/m strength geogrids
High-strength geogrids designed and installed for slope
stabilization on Florianopolis Ring Road in Brazil.

I
n 2015, a variant road was built to relieve urban traffic in the
southeastern section of federal road BR 101, more precisely in
Florianopolis, which is the capital city of Santa Catarina, Brazil.
With a length of 4,828 km (3,000 miles), BR-101 is a major
Brazilian highway that runs the length of Brazil, from the city
of Touros in the north to Sao Jose do Norte in the south of the
country. In constructing this road, very challenging slope stability
problems associated with very soft soils, which contained peat
and turf, were predominant. Very high-strength geogrids were
required to ensure the sliding stability of the slopes located in the
most critical section, which had a length of about 15 km (9 miles)
and up to 12 m (39 feet) in height. This paper aims to describes the
design, installation and, most importantly, characteristics of the
slope stabilization using a very high ultimate strength polyester
geogrid (1,750 kN/m [120,000 lb/ft]); so far, the highest strength
geogrid used for this purpose known by the authors of this paper.
The Ring Road of the Metropolitan Region of Florianopolis
is a major part of the Brazilian road infrastructure. Due to the
high complexity of the soil conditions in the region and the great
extents of the highway exceeding 50 km (31 miles), several technical
and constructive challenges had to be overcome.
The aim of constructing this variant road was to create
an expressway that would avoid the metropolitan area of
Florianopolis, providing an alternative route to the BR-101 traffic,
avoiding the metropolitan region and allowing for more efficient
urban mobility. Construction on the Florianopolis Ring Road
