  1. 1. Investigation of the structural response of pavements in cold region using instrumented test site data

    Författare :Denis Saliko; Sigurdur Erlingsson; Pauli Kolisoja; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; flexible pavement; environmental impact; seasonal variation; heavy loading; non-destructive testing; instrumented section; Flexibla vägkonstruktioner; Omgivningspåverkan; Säsongvariation; Tung trafikbelastning; Oförstörande provning; Instrumenterade teststräckor; Byggvetenskap; Civil and Architectural Engineering; Building Materials; Byggnadsmaterial;

    Sammanfattning : The structural behaviour of pavement structures is known to be affected by the traffic-related loading and by the ambient factors to which the structure is subjected. A new mechanistic-empirical (M-E) pavement design method is under development in Sweden with the main purpose to adequately predict pavement structural response and performance. LÄS MER

  3. 2. 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.

  4. 3. Moisture Influence on Structural Behaviour of Pavements : Field and Laboratory Investigations

    Författare :Farhad Salour; Sigurdur Erlingsson; Guy Doré; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Falling Weight Deflectometer FWD ; backcalculation; unbound material; subgrade; seasonal variation; moisture content; spring-thaw; drainage; pavement stiffness; field test; pavement instrumentation; resilient modulus; permanent deformation; repeated load triaxial test; unsaturated soil; matric suction.; Civil and Architectural Engineering; Byggvetenskap; Transportvetenskap; Transport Science;

    Sammanfattning : The structural behaviour of pavements in cold regions can considerably be affected by seasonal variation in environmental factors such as temperature and moisture content. Along with the destructive effect of heavy traffic loads, climatic and environmental factors can considerably contribute to pavement deterioration. LÄS MER

  5. 4. Aerothermal Experimental Investigation of LPT-OGVs

    Författare :Borja Rojo; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Experimental; Turbine Rear Structure; Aerodynamics; Wind Tunnel; CFD; Gas Turbine; Engine Exit Structure; Outlet Guide Vane; Heat transfer.; Turbine Exhaust Case; Turbine Rear Frame; Exit Guide Vane;

    Sammanfattning : This thesis presents the design, commissioning, and experimental data of a newly built turbine facility at Chalmers University of Technology for investigating the ow in the engine exit structure (EES). The EES is the structure located downstream of the lowpressure turbine (LPT) in a jet engine. LÄS MER
