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

    Author : Farhad Salour; Sigurdur Erlingsson; Guy Doré; KTH; []
    Keywords : 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;

    Abstract : 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. READ MORE

  4. 2. Surface Wave Testing of Pavements

    Author : Nils Rydén; Teknisk geologi; []
    Keywords : 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;

    Abstract : 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. READ MORE

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

    Author : Denis Saliko; Sigurdur Erlingsson; Pauli Kolisoja; KTH; []
    Keywords : 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;

    Abstract : 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. READ MORE

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

    Author : Mohammad Shafiqur Rahman; Sigurdur Erlingsson; Charles Schwartz; KTH; []
    Keywords : 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;

    Abstract : 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. READ MORE

  7. 5. Climate impact on the durability of asphalt concrete

    Author : Pajtim Sulejmani; Trafik och väg; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Roads are subjected to traffic loads and varying climate conditions that eventually lead to different types of damage. Moisture in asphalt is one of the major causes of premature failure in asphalt pavements. READ MORE
