  1. 1. Life Cycle Costing in Road Planning and Management A Case Study on Collision-free Roads

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Jonas Wennström; KTH.; [2014]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; collision-free road; design; infrastructure; investment; life cycle costing; life cycle cost analysis; maintenance; management; operation; planning; road; sustainability;

    Sammanfattning : Construction of infrastructure does not only mean large capital investments but also future costs to operate and maintain these assets. Decision making in planning and design of roads will impact the need of future operation and maintenance activities. LÄS MER

  2. 2. Vehicle-Pavement Interaction

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

  4. 4. Mechanistic-Empirical Modelling of Flexible Pavement Performance Verifications Using APT Measurements

    Detta är en avhandling från Stockholm : US-AB

    Författare :Abubeker Worake Ahmed; KTH.; Statens väg- och transportforskningsinstitut.; [2014]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Transportvetenskap; Transport Science; Civil and Architectural Engineering; Byggvetenskap; Flexible Pavement; Pavement Performance Models; Multilayer Elastic Theory; Linear Viscoelasticity; Rutting; Accelerated Pavement Testing; Heavy Vehicle Simulator; Road: Pavement design; Road: Pavement design; Performance; Deformation; Model not math ; Rutting wheel ; Viscoelasticity; Elasticity; Axle load; Flexible pavement; Laboratory not an organization ; Test; Thesis; Heavy vehicle simulator; Wheel tracking test;

    Sammanfattning : Mechanistic-Empirical  (M-E)  pavement  design  procedures  are  composed  of  a  reliable  response model to estimate the state of stress in the pavement and distress models in order to predict the different types of pavement distresses due to the prevailing traffic and environmental conditions. One of the main objectives of this study was to develop a response model based on multilayer elastic  theory   (MLET)  with  improved  computational  performance  by   optimizing  the   time consuming parts of the MLET processes.

  5. 5. Surface Wave Testing of Pavements

    Detta är en avhandling från Nils Ryden, Department of Engineering Gelogy, Lund Institute of Technology, Lund University, BOX 118, 22100 Lund

    Författare :Nils Rydén; Lunds universitet.; Lund University.; [2004]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; geographical and geological engineering; Hydrogeologi; teknisk geologi; teknisk geografi; Hydrogeology; inversion; guided waves; road; pavement; Surface waves; non-destructive testing;

    Sammanfattning : A novel approach for surface wave testing of pavements is presented. It is a non-destructive testing (NDT) technique that can be used to obtain the thickness and stiffness properties of the different layers in a pavement. LÄS MER
