Slopes on Roads in the Lisbon District

Client:​ Infraestrutras de Portugal

Projects: Slopes on Roads in the Lisbon District - EN 115-5 Km5+150

Description: The purpose of the contract was to stabilise the embankment slope of the EN115-5 at KM 5+150, using Ø8OOmm piles and Ø5OOmm rigid inclusions.

High-strength uniaxial geogrid was used to provide the foundation with load-bearing capacity and to stabilise it.

To support the granular and bituminous layers, a reinforced concrete crown beam was built and reinforced with micropiles. The granular layers (ABGE) and the corresponding bituminous layers were then applied.
