    Abstract : Glacifluviala avlagringar har varit de vanligaste källorna för byggmaterial i Sverige under de senaste decennierna. De är dock ändliga resurser som måste bevaras eftersom de också fungerar som akvifärer. READ MORE

  4. 18. Simulation of railway infrastructure with asphalt layer for tracks in Sweden

    University essay from KTH/Byggvetenskap

    Author : Aleksandra Kuksova; [2020]
    Keywords : Ballasted track; bituminous mixture; bituminous sub-ballast; temperature; railway track modelling; finite element analysis. v;

    Abstract : With the introduction of high-speed trains over the past few years, as well as withan increase in traffic loads and volumes, the attractiveness and competitiveness ofthe railway transport system have increased. This leads to the need to develop newcost-effective ways in railway construction, providing an increase in the life cycle ofthe railway track and reducing the need for maintenance. READ MORE
