Airport pavements must sometimes be constructed on very soft ground – which creates considerable challenges for engineers. Tensar Geogrids can strengthen weak subgrades and control differential settlement, creating a mechanically stabilized layer for taxiways and runways, which is able to cope with the intense loads from aircraft movements. This construction design reduces the aggregate needed, therefore extending service life and producing the potential for significant time, cost and environmental benefits.


Resurfacing runways and taxiways

Where existing runways are prone to reflective or fatigue cracking and require resurfacing, Tensar’s GlasGrid Asphalt Reinforcement System and GlasPave Asphalt Reinforcement System can be the perfect design solution, able to be laid over most existing surfaces. GlasGrid can inhibit cracking and the composite products reinforce. Moreover, GlasPave can also provide a low permeability barrier to the deleterious effects of water infiltration, further extending the pavement life and reducing future maintenance costs.

Building barriers

In environmentally sensitive or built-up areas, steep earth bunds may be used as visual, blast or noise barriers. Tensar Retaining Wall Systems are not only able to create a stable barrier, but also allow the possible use of site-won materials as fill – further adding to the environmental benefits. Other Tensar systems offer protection against soil erosion in areas subject to jet blast damage, in addition to conditions such as drainage channels and swales.

Tensar International offers state-of-the-art design solutions that can be used to create stable foundations for airport pavements.

With more than 30 years of experience on projects worldwide, the proven benefits of Tensar’s systems can include:

  • Reduced unbound aggregate layer thickness
  • Reduced construction costs
  • Reduced excavation
  • Lower long-term costs
