Tensar TriAx Carbon Calculator
Over recent years, there has been increased concern over rising CO2 emissions worldwide. In response to this, the UK government has committed to reducing CO2 emissions by 20% in real terms by 2010. Since 2007, the UK government’s planning policy statement states that the design of any future development should be planned to limit CO2 emissions.
The Tensar Carbon Calculator estimates the percentage CO2 saving by using Tensar TriAx geogrid in a mechanically stabilised layer when compared to the construction of an unstabilised road foundation. This saving is due to the Tensar mechanically stabilised layer enabling a lesser thickness of aggregate to be used for the construction of the road foundation.
The use of Tensar TriAx geogrids within a mechanically stabilised layer enables reductions in aggregate layer thickness, therefore
•reducing the quantities of natural aggregates used
•reducing the volume of material to be excavated
•reducing the number of vehicles visiting the site
All of these reductions enable a saving in CO2 emissions.
Taking into consideration the carbon cost of manufacturing Tensar TriAx geogrids and delivering the geogrids to site, the Tensar Carbon Calculator works out the potential savings in materials and transport when using TriAx geogrid in a mechanically stabilised layer. Savings in CO2 emissions of up to 50% can be achieved when compared with an unstabilised road foundation.
The calculator has been developed and checked by Coffey Geotechnics.
