  2. 1. Vehicle-Pavement Interaction

    Author : Parisa Khavassefat; Björn Birgisson; Denis Jelagin; David Cebon; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Finite element; Viscoelasticity; Moving load; Dynamic axle loads; Road roughness; Flexible pavement; Stochastic;

    Abstract : Several aspects of vehicle-pavement interaction have been studied and discussed in this thesis. Initially the pavement response is studied through a quasi-static and a dynamic computationally efficient framework under moving traffic loads. READ MORE

  5. 3. Mixed-Grained Till in Pavement Structures; A Field and Laboratory Study

    Author : Helene Kennedy; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; permanent deformation behaviour; triaxial test; pavement; till;

    Abstract : The road network in Sweden has historically been constructed using rock fill and natural gravel. More than 75 per cent of the land surface of Sweden is covered by glacial till and greater utilization of site-won material will not only reduce transportation costs but will also promote better sustainability of natural assets.

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

    Author : Markus Svensson; Sigurdur Erlingsson; Helge Mork; Statens väg- och transportforskningsinstitut; []
    Keywords : 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;

    Abstract : 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. READ MORE

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

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

    Abstract : 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. READ MORE
