  2. 21. Life Cycle Assessment of Asphalt Roads : Decision Support at the Project Level

    Author : Ali Azhar Butt; Björn Birgisson; Nicole Kringos; Susanna Toller; Stephen T. Muench; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Asphalt roads; life cycle assessment; feedstock energy; warm mix asphalt additives; green procurement; decision support; laboratory investigation; pavement design.; Byggvetenskap; Civil and Architectural Engineering; Transportvetenskap; Transport Science;

    Abstract : Transport infrastructures such as roads are assets for the society as they not only ensure mobility but also strengthen society’s economy. Considerable amount of energy and materials, that include bitumen, aggregates and asphalt, are required to build and maintain roads. READ MORE

    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Information modelling; manufacturing resource model; manufacturing system life cycle; STEP; PLCS; Informatics; Informatik;

    Abstract : This thesis deals with information modelling within the scope of the manufacturing system life cycle, i.e. the development phase and the operation phase. READ MORE

  5. 23. System Expansion and Allocation in Life Cycle Assessment With Implications for Wastepaper Management

    Author : Tomas Ekvall; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; modelling; paper recycling; waste incineration; environmental life cycle assessment; LCI methodology; allocation; waste management; system expansion; system boundaries; life cycle inventory analysis;

    Abstract : The choice of system boundaries and allocation methods can have decisive effects on the results and conclusions of a life cycle assessment (LCA). System expansion makes it possible to model the indirect effects of a decision; however, this modelling is often based on inaccurate assumptions. READ MORE

  6. 24. Strategic Life-Cycle Modeling for Sustainable Product Development

    Author : Henrik Ny; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; backcasting; life-cycle assessment LCA ; modeling; planning;

    Abstract : Decision makers are challenged by complex sustainability problems within the socio-ecological system. In response, a vast range of sustainability-related methods/tools have been developed, each focusing on certain aspects of this challenge. READ MORE

  7. 25. Life cycle behaviour of concrete bridges : laboratory test and probabilistic evaluation

    Author : Markus Bergström; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik;

    Abstract : The structural life for a concrete structure located in an environment where corrosion is promoted by humidity or chlorides from sea or de-icing salt could in general be described in the following manner. The structure is manufactured and is at that point considered to be intact. READ MORE
