   Författare :Babak Ebrahimi; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LCCA; LCA; road infrastructure; SLR; survival analysis; modelling; lifetime; GIS;

   Sammanfattning : Roads are transport infrastructures that play a fundamental role in the development of societies and businesses. They are valuable assets, as they connect places, provide mobility, create jobs and stimulate economic prosperity. LÄS MER

3. 2. Sustainable Personal Road Transport : The Role of Electric Vehicles

   Författare :Sven Borén; Göran Broman; Henrik Ny; Louise Trygg; Jamil Khan; Blekinge Tekniska Högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strategic Sustainable Development; Transport Planning; Electric Vehicles; Testing; LCA;

   Sammanfattning : Electric vehicles can play an important role in a future sustainable road transport system and many Swedish politicians would like to see them implemented faster. This is likely desirable to reach the target of a fossil independent vehicle fleet in Sweden by 2030 and a greenhouse gas neutral Swedish society no later than 2050. LÄS MER

4. 3. Stainless Steel Corrugated Web Girders for Composite Road Bridges: Concept Evaluation and Flange Buckling Resistance

   Författare :Fatima Hlal; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Investment cost; Genetic algorithm; Duplex stainless steel; LCC; Corrugated web; Flange buckling resistance; Optimization; Composite bridges; LCA; Road bridges;

   Sammanfattning : Achieving a sustainable bridge design requires careful consideration of economic viability and environmental impact over the entire lifespan of the structure. While stainless steel is recognized for its excellent life cycle performance, its high cost prevents it from being used to a larger extent in bridges. LÄS MER

5. 4. Environmental Considerations in the Zero-waste Valorisation of Bauxite Residue : A Life Cycle Perspective

   Författare :Peter James Joyce; Anna Björklund; Hellweg Stefanie; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Life Cycle Assessment LCA ; bauxite residue; waste valorisation; Naturally Occurring Radioactive Materials NORM ; Life Cycle Thinking; LCA software; Circular Economy; Livscykelanalys LCA ; bauxitrest; avfallsvalorisering; naturligt förekommande radioaktiva ämnen NORM ; livscykeltänkande; LCA-programvara; cirkulär ekonomi; Planering och beslutsanalys; Planning and Decision Analysis;

   Sammanfattning : Bauxite residue, also known as red mud, is produced in large quantities as a result of alumina refining (the first stage in aluminium production), and is one of the world’s most abundant and important industrial wastes. As demand for aluminium continues to increase and space to store this residue diminishes, the potential to utilise bauxite residue as a secondary resource is increasingly being considered by the alumina industry.

7. 5. Life Cycle Impacts of Road Infrastructure : Assessment of energy use and greenhouse gas emissions

   Författare :Sofiia Miliutenko; Anna Björklund; Robert Karlsson; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Cumulative Energy Demand CED ; Global Warming Potential GWP ; Life Cycle Assessment LCA ; road infrastructure; strategic planning;

   Sammanfattning : Road infrastructure is essential in the development of human society, but has both negative and positive impacts. Large amounts of money and natural resources are spent each year on its construction, operation and maintenance. Obviously, there is potentially significantenvironmental impact associated with these activities. LÄS MER
