  2. 1. Investigation of asphalt compaction in vision of improving asphalt pavements

    Author : Ehsan Ghafoori Roozbahany; Manfred N. Partl; Gabriele Tebaldi; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cold asphalt pavement joints; asphalt joint laboratory production; IDT joint evaluation; DTT joint evaluation; 4PB joint evaluation; joints FEM analysis. Discrete Element Modeling DEM ; X-ray Computed Tomography CT ; Compaction Flow Test CFT ; Compactability;

    Abstract : Asphalt joints are potentially weakest parts of every pavement. Despite of their importance, reliable tools for measuring their mechanical properties for design and performance assessments are still scarce. READ MORE

  4. 2. Prediction of permanent deformations in asphalt concrete using the mechanistic-empirical pavement design guide

    Author : Erik Oscarsson; Trafik och väg; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; permanent deformation; design guide; asphalt concrete; mechanistic empirical;

    Abstract : Permanent deformations, or rutting, are internationally considered to be one of the most serious distress mechanisms in asphalt pavements. Deterioration modeling is an important tool for performance prediction and diagnostics of pavements. READ MORE

  5. 3. Sickness absence among patients with chronic pain in Swedish specialist healthcare

    Author : Riccardo Lo Martire; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Background: Chronic pain beyond three months is a global public health problem. Every third adult suffers from a chronic pain condition, resulting in a socioeconomic burden that corresponds to 3-10% of gross domestic product in western economies. READ MORE

  6. 4. Thermally Induced Fracture Performance of Asphalt Mixtures

    Author : Prabir Kumar Das; Björn Birgisson; Dallas Little; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Low temperature cracking; asphalt concrete fracture mechanics; viscoelasticity; non-linear thermal contraction coefficient; atomic force microscopy; wax; wax crystallization; SRA - Transport; SRA - Transport;

    Abstract : A major distress mode in asphalt pavements is low temperature cracking, which results from the contraction and expansion of the asphalt pavement under extreme temperature changes. The potential for low temperature cracking is an interplay between the environment, the road structure and importantly the properties of the asphalt mixture. READ MORE

  7. 5. Organisational Adoption of Innovations : Management Practices and IT

    Author : Erik Lundmark; Alf Westelius; Nils-Göran Olve; Pär Mårtensson; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Innovation; adoption; Non Profit Organisations; NPO; SME; ISO 9000; information technology; IT; ICT; communication; Technology Acceptance Model; TAM; Sport; Information technology; Informationsteknik; Economic Information Systems; Ekonomiska informationssystem;

    Abstract : This thesis describes effects of use and reasons for using three different organisational innovations: ISO 9000, Information and Communication Technologies (ICT) and an administrative tool (the YAF-module) in the Swedish Sports Confederation’s system Swedish Sports Online. This is done through three separate studies. READ MORE
