Ever since its invention, Reinforced Earth® has been used in the construction of wide range of road structures.
Most types of road infrastructure building requirements precisely match the universal application of Reinforced Earth® flagship solution. It is an excellent fit for the MSE walls for road structures. Constructing roads involves creating a path through existing terrain and therefore requires cutting through hills and uneven landscape or widening and rehabilitating existing infrastructure. Over the past decades, our team of engineers and designers has gained a wealth of knowledge and experience in developing engineered solutions for the most challenging situations for dealing with all types of soils, project constraints, and land formations.
MSE retaining walls for roads
Soft soils require stabilization to secure the infrastructure and mitigate any possible risk of sliding. For more than 60 years the resilient and flexible Reinforced Earth® technology is being widely used throughout the world for building vertical MSE walls for road structures that can be single-tier or multi-tier. The Reinforced Earth® technology can accommodate different types of backfills and a wide range of soil reinforcements that are made from steel or geosynthetic. Retaining walls for roads can also be designed and built using our other precast modular retaining walls such as T-Wall™.
Understanding the soil conditions and long-term behavior of traffic is of utmost importance when building a road, especially when dealing with poor soil conditions and low bearing capacity. With our range of products combined with our decades of engineering expertise, we can offer excellent soil stabilization for roads under challenging conditions while reducing costs and construction time while assuring long service lives.
Buried bridge structures and tunnels
When building roads, it is inevitable that certain natural obstructions will need to be traversed. Sometimes it could be crossing rivers, cutting through mountainous terrain or crossing a wildlife sanctuary. These obstacles can be overcome by building arch bridges, cut and cover tunnels, dedicated wildlife crossings or buried bridge structures that can be single or multi-span depending on the situation. In these instances, our TechSpan® precast concrete arches are a proven solution with a wide range of standardized arch profiles available reaching up to 22m span, and even larger spans for special projects. Our TechSpan® arches can also be combined with Reinforced Earth® MSE retaining walls as part of a completely integrated and engineered solution.
Please visit our precastarches.com website, which is dedicated to TechSpan®, where you can easily download our full catalog of shapes in pdf format. The website also facilitates quick calculations using the TechSpan® Design Tool to determine the optimal arch shape for your next project and to download it in .dwg AutoCAD compatible format.
Access ramps and bridge abutments
The transition from a roadway embankment to a bridge can come in many forms. Access ramps are one such instance and our retaining wall solutions are widely used in the construction of these access ramps. When constructing roads, the bridge abutments are considered critical structures. Our solutions are well suited to addressing load distribution and settlement requirements of bridge abutments because whether pile-supported or fill-supported, bridge abutments are dependent on confined stabilized soil. Our earth retaining solutions are customized and optimized to address unique conditions that are specific to each bridge application.
With the constant increase in traffic created by the rapid development in urban areas, roads often require widening to increase their capacity. Our retaining wall solutions can increase the width of the roadway while ensuring the continuity of service of the existing infrastructure. Our TerraLink® shored retaining wall solution has proven to be an excellent option for road widening applications, allowing us to link a new structure to an existing one.
Temporary roadway and bridge phasing
Highway construction often requires temporary shifts of traffic to mitigate huge traffic jams. Our TerraTrel® temporary wire mesh Mechanically Stabilized Earth (MSE) retaining wall solutions allow for easy handling and quick installation, with the same load-carrying capacity as precast concrete faced MSE walls.
Traffic barrier & precast copings
Building elevated MSE walls for road structures call for measures to ensure the safety of road users on top. Our precast traffic barriers offer a robust connection along the walls and are proven through real-life full-scale crash testing and numerical modeling. Several types of safety barriers can be integrated with our walls and made available as part of our complete offering:
– Traffic barriers
Sound Absorbing Panels
Building roads and motorways nearby residential areas can imply noise disturbance for the local residence. Our sound-absorbing panels can be installed in these areas to mitigate the sound.
Our robust precast panels for MSE walls for road structures can be customized with architectural finishes, allowing designers and architects to add a touch of art to the structures.
