Roads and Highways

From major motorways to haul roads, Tensar’s geogrid technology is a proven solution to ground stabilisation problems, increasing pavement life, repair and rehabilitation, helping you to control construction costs and build-in better performance life to your roads. Our 30 years’ experience extends to the design and supply of reinforced soil bridge abutments, retaining walls and embankments, too.

Creating a stable foundation to roads

Weak or variable ground can present a considerable challenge in road construction. But creating a mechanically stabilised layer using Tensar geogrids can produce significant cost, time and environmental benefits.

• Capping and sub-base layers can be reduced up to 50% with no performance loss, reducing fill material and excavation costs, time on site and construction CO₂ emissions
• Differential settlement on variable ground can be controlled using layers of geogrids to create a flexurally stiff platform
• Geogrids can be used to improve site access and increase the bearing capacity of working platforms for tracked plant, promoting safety with economical designs

Alleviating the maintenance burden

With a mechanically stabilised layer a road’s service life can be extended by a factor of three or more, reducing long-term maintenance costs. In fact, it’s been estimated that a reduction in road and rehabilitation cost can produce over 50% savings on annual maintenance budgets for flexible pavements. Tensar’s asphalt reinforcement systems are designed to tackle pavement problems, such as reflective and fatigue cracking.

Tensar has the answer for retaining walls and steep embankments, too

Many highway projects involve creating walls, embankments, bridge abutments and other features. Tensar also has extensive experience in these areas, with specific systems for the construction of walls and embankments as well as erosion protection.

Embankment Foundations

When embankments have to be built over poor ground Tensar Basetex can provide the necessary stability or alternatively a TensarTech Geocell Mattress System can be used to achieve stability and control differential settlement. Where settlement restrictions dictate or there is insufficient time available for it to take place then our Load Transfer Platforms over piles or Rammed Aggregate piers are a simple alternative to costly concrete rafts and ground beams.
