  3. 7. Smart pavement maintenance and infrastructure operation through digital twins : Case study for Norvik Port, Sweden

    Författare :Julian Dario Rodriguez; Nicole Kringos; Romain Balieu; Plati Christina; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; pavement management; digital twins; finite element model pavement; infrastructure maintenance.; Vägunderhåll; Digitala tvillingar; Ändliga elementmodeller för vägar; Infrastrukturförvaltning; Civil and Architectural Engineering; Byggvetenskap; Bro- och stålbyggnad; Structural Engineering and Bridges;

    Sammanfattning : There is an urgent need to make the way in which people and goods move more sustainable. Though pavements are one of the key components of road transportation networks and logistics systems, they are usually overlooked in systemic sustainability analyses. LÄS MER

  4. 8. Modeling pavement performance based on data from the Swedish LTPP database : predicting cracking and rutting

    Författare :Markus Svensson; Sigurdur Erlingsson; Helge Mork; Statens väg- och transportforskningsinstitut; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cracking; Rutting wheel ; Prediction; Calculation; Mathematical model; Flexible pavement; Performance; Sprickbildning; Spårbildning; Förutsägelser; Beräkning; Matematiska modeller; Flexibla överbyggnader; Prestanda; 32 Road: Pavement design; 32 Road: Pavement design;

    Sammanfattning : The roads in our society are in a state of constant degradation. The reasons for this are many, and therefore constructed to have a certain lifetime before being reconstructed. To minimize the cost of maintaining the important transport road network high quality prediction models are needed. LÄS MER

  5. 9. Deterioration Models and Road Capital as Tools in Performance Contracts for Pavement Maintenance

    Författare :Peter Ekdahl; Trafik och väg; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknik; pavement management system; performance contract; pavement maintenance; deterioration model; Technological sciences; road capital; Social sciences; Samhällsvetenskaper;

    Sammanfattning : A reorganization of the Swedish National Road Administration (SNRA) has urged a demand to work as a professional agency only, without any work by direct labor. This structure has enforced a change in how to handle the pavement maintenance and performance contracts are being promoted since they encourage product development and sustainability. LÄS MER

  7. 10. Pavement Response to Moving Loads

    Författare :Parisa Khavassefat; Björn Birgisson; Denis Jelagin; Andrew Collop; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The response of flexible pavements at vehicle-road interaction has been studied in this thesis. A quasi-static and a dynamic framework for analysing the pavement structure under moving load has been developed. Both frameworks are general, robust and computationally efficient. LÄS MER
