As roads and bridges are resurfaced, old concrete is removed and is usually discarded. It would be in the best interest of SHA, in support of its sustainability initiatives, that these materials be recycled and repurposed for alternative uses. One such potential use is to condition portions of the Chesapeake Bay bottom to support spat-on-shell aquaculture projects. For recycled concrete ...

The Carbon Impact of the National Roads Programme Final

embodied carbon in the steel, concrete, asphalt and other raw materials used to build it. If there is extensive land clearance and many mature trees are felled, a carbon sink is lost. Once the road is opened, it may result in higher speeds, and this may lead to more carbon emissions: an increase in average speeds from 60mph to 70mph causes carbon emissions to go up by about 13%. And over
