how sustainable is…
This envormation summary is based on a slide show presentation summarising the environmental impact of roads made from concrete (concrete pavement). The study covers the entire road lifecycle, from mining of raw materials and construction, to road use and demolition.
The summary suggests the following with regards to global warming potential of concrete roads over their entire life (in the US, based on a number of assumptions – please follow the link below for details):
The summary also details what elements contribute to the GWP suggested above, such as aggregate mining and cement transport etc. It suggests that the biggest contributor to GWP is cement production and the second biggest contributor is fuel consumed due to road surface roughness (the slides do not provide further details on this aspect).

While we make every effort to be accurate, we do not claim that this summary is representative. Please refer to our Legal Disclaimer for details.
