  1. 1. Validation of heavy vehicle loading responses and temperature predictions in flexible pavements using field data

    Författare :Denis Saliko; Sigurdur Erlingsson; Abubeker Ahmed; Denis Jelagin; Inge Hoff; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Flexible pavements; Long heavy vehicles; Instrumented test section; Field validation; Non-destructive testing; Temperature modelling; Flexibla vägkonstruktioner; Tung trafikbelastning; Instrumenterade teststräckor; Fältvalidering; Oförstörande provning; Termisk modellering; Building Materials; Byggnadsmaterial;

    Sammanfattning : It is well established that both traffic-related loading and environmental conditions influence the structural behaviour of pavements. Pavement design methods aim to consider the effect of traffic loading and environmental variables on pavement structure, foresee their changes during the lifetime of the pavement and predict the resulting distresses and pavement life.

  3. 2. Frictional Effects on Hertzian Contact and Fracture

    Författare :Denis Jelagin; Per-Lennart Larsson; Bertil Storåkers; David Hills; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Contact mechanics; Elastic material; Friction; Nanoindentation; Fracture; Solid mechanics; Fastkroppsmekanik;

    Sammanfattning : This thesis addresses normal axisymmetric contact of dissimilar elastic solids at finite interfacial friction. It is shown that in the case of smooth and convex but otherwise arbitrary contact profiles and monotonically increasing loading a single stick-slip contour evolves being independent of loading and profile geometry.

  5. 4. Packing theory-based Framework for Performance Evaluation of Unbound Granular Materials

    Författare :Tatek Fekadu Yideti; Björn Birgisson; Denis Jelagin; Tutumluer Erol; KTH; []
    Nyckelord :;

    Sammanfattning : Enhancing the load bearing quality of granular layers is fundamental to optimize the structural performance of the pavements. Unbound granular materials are one of the most used materials in the base layers of pavements. There have been growing interests on the behavior of unbound granular material in road base layers.

  7. 5. Evaluation of Low Temperature Damage in Asphalt Mixtures with Non-Contact Resonance Testing

    Författare :Abiy Bekele; Denis Jelagin; William Buttlar; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Asphalt concrete; dynamic modulus; non-contact excitation; resonance testing; thermally induced damage; viscoelasticity; Asfaltbetong; beröringsfri excitation; resonansfrekvens; resonansprovning; styvhetsmodul; Building Materials; Byggnadsmaterial;

    Sammanfattning : Thetemperature induceddamage in asphalt mixtureshas always been a major distress that requires a substantialconsiderationin the asphalt industry. One of the most important aspects of studying temperature induceddamage is developing a practical test method for evaluation of the material’s resistanceto it. LÄS MER
