In our modern world, energy is needed for almost every important process, including road construction, according tomedia CNET. There has to be someone to make asphalt and concrete, there has to be something to transport materials, and that requires energy. A new study from the Swedish University of Technology at Chalmers and the University of Gothenburg highlights areas where people can actually cut emissions from road construction in half.
The study focused on a five-mile stretch of road in Sweden, and every part of the study, whether material or any related activity, was included in the overall climate impact.
Ida Karlsson, a doctoral student at Chalmers University of Technology, said the researchers analyzed today’s alternatives and found that these inputs could reduce emissions by 20 percent compared to the Swedish Transport Authority’s reference values. However, using more today’s technologies could reduce emissions by 50%.
Karlsson highlighted the use of electric vehicles to transport things between construction sites, recycle and reuse materials excavated from construction sites, and replace cement clinker as a binder for concrete. These are achievable today, although the study acknowledges that each item requires considerable investment. Looking ahead, these areas could help eliminate emissions associated with road construction completely by 2045.
