  1. 1. Moisture Influence on Structural Behaviour of Pavements Field and Laboratory Investigations

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

    Författare :Farhad Salour; KTH.; [2015]
    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

  2. 2. Characterising the Deformation Behaviour of Unbound Granular Materials in Pavement Structures

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

    Författare :Mohammad Shafiqur Rahman; KTH.; [2015]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; unbound granular materials; resilient modulus; permanent deformation; moisture; model; multistage; repeated-load triaxial test; Transportvetenskap; Transport Science; Civil and Architectural Engineering; Byggvetenskap;

    Sammanfattning : Unbound granular materials (UGMs) used in the base and sub-base layers of flexible pavements play a significant role in the overall performance of the structure. Proper understanding and characterization of the deformation behaviour of UGMs in pavement structures are, therefore, vital for the design and maintenance of flexible pavements. LÄS MER

  3. 3. Resilient and permanent deformation behavior of unbound aggregates under repeated loading

    Detta är en avhandling från Institutionen för infrastruktur och samhällsplanering

    Författare :Fredrick Lekarp; KTH.; [1999]
    Nyckelord :;

    Sammanfattning : During recent decades, growing interest in the developmentof so-called analytical or mechanistic road pavement designmethods has resulted in substantial research into themechanical behavior of the materials involved. In flexiblepavements, especially when unsurfaced or thinly surfaced,overall structural performance is largely dependent on thebehavior of the unbound granular base and subbase layers. LÄS MER
