Klimatpåverkan vid vägbyggnad -beroende av vald konstruktion

It’s a fact that the climate is affected by the vehicle that runs on the worlds roads. But the construction of the road itself is rarely thought of as a climate threat. Svevia and the Swedish road administration have opposite views of how the construction of roads should be carried thru. It’s the difference between those two construction methods that is the base in our thesis. The amount of energy use or the emissions are not analyzed for neither the Swedish road administrations nor Svevias construction models. Our thesis has compared these two models of constructing a road to evaluate what affects the climate the least. In other words which material and which construction model that is best to use to reduce the impact on the climate. We have calculated the total amount of carbon dioxide and energy use for road models in different traffic classes. To do this we designed a calculation tool that calculates on the total amount of MWh used and the total amount of tons carbon dioxide emitted during the construction of a road. This calculation tool could even in the future be used to calculate energy use and emissions from new types of construction models. The results for the construction models we calculated is that Svevias construction models have a tendency to have some less emissions of carbon dioxide and demand somewhat less energy than the Swedish road administration construction models. A difference also shows between different traffic classes. Traffic class low gives considerably fewer emissions and demands less energy use than traffic class high
