Abstract [sv]

Klimatpåverkan och energiförbrukning är ett av de stora miljöproblemen runt om i världen idag. Sedan den industriella revolutionens start har mängden utsläpp av bland annat koldioxid ökat exponentiellt med årens lopp och skapat obalans i klimatet, inte minst på grund av restprodukter och skadliga ämnen som används inom bland annat byggindustrin. Syftet med denna studie är att ta reda på vilka arbetsmoment som har störst påverkan på miljön för att sedan, om möjligt, ta fram förslag på hur det kan förbättras. Frågeställningen vi utgått från vid genomförandet av denna studie har varit; “Av de arbetsmetoder vid ett bygge av en väg, vilken del är mest skadlig för miljön?”. Den huvudsakliga metoden för detta arbete har varit en fallstudie där en undersökning om ett projekt har gjorts. Ett antal klimatkalkyler med olika vägmaterialsegenskaper gjordes som sedan jämfördes mot varandra. Av dessa kalkyler kunde slutsatsen att kallasfalt släpper ut mycket mindre koldioxid jämfört med vanlig asfalt men det krävs mer forskning kring detta för att kunna dra en säkrare slutsats.

Abstract [en]

Climate impact and energy consumption are one of the biggest environmental problems around the world today. Since the start of the industrial revolution, the amount of carbon dioxide emissions has increased exponentially over the years. These emissions created imbalances in the climate, not least because of residues and harmful substances used in the construction industry. The purpose of this study is to find out which methods have the greatest impact on the environment, and then, if possible, make suggestions on how it can be improved. The issue we have researched in this study has been; "what method of building a road is most harmful to the environment?”. The main method of this work has been a case study in which a survey of a project has been conducted. A number of climate calculations with different road material properties were made which were then compared to each other. The conclusion we were able to make is that cold-asphalt releases much less carbon dioxide than normal asphalt, but more research is needed to draw a more accurate and reliable conclusion.
