ROAD WIDENING WITH TERRAMESH AND GEOGRIDS
LORETO APRUTINO – PESCARA, ITALY
REINFORCED SOIL WALLS AND SLOPE REINFORCEMENT
Product: Green Terramesh & Terramesh System
Problem
The Highways Department for the Abruzzo Region tendered a contract for the construction
works to eliminate the sharp bends in the stretch
of road between the junction with the Remontello
Provincial Highway and the town of Loreto Aprutino (Pescara). These works affected a section of
State Highway 151 “Valle del Tavo”.
Solution
The project included the horizontal and vertical
remodelling of the road alignment, with widening
of several stretches. In order to minimise the environmental impact of the works, the designer
decided to adopt reinforced soil technology using
Terramesh. The lowest sections were formed by
a front face of gabions whilst, for the upper sections, a facing which could be covered with vegetation was preferred.
During construction
In order to minimise the costs, the main reinforcement elements high-strength used Paralink, a
polyester geogrid covered with polyethylene. The
ultimate strengths of the geogrids used for this
project were 400 and 800 kN/m and they were
placed in a staggered manner as specified in the
design.
