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 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 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.
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.
