  1. 26. Flow behavior of asphalt mixtures under compaction

    Författare :Ehsan Ghafoori Roozbahany; Manfred N. Partl; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Transportvetenskap; Transport Science;

    Sammanfattning : Asphalt compaction is one of the most important phases of road construction, being the decisive phase when the structure of the asphalt pavement layer is formed. In spite of its importance, the knowledge about this construction phase is still based on empirical and technological background and therefore surprisingly limited. LÄS MER

  3. 27. On friction in metal power compaction process

    Författare :Naghi Solimannezhad; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Maskinelement; Machine Elements;

    Sammanfattning : The present work describes different ways of measuring and studying friction in a metal powder compaction process. Reducing friction during this process will allow an increase in the density of powder components and reduce variation in the density, which is a common problem in this process. This work contain three papers. LÄS MER

  4. 28. Compaction and thaw deformation of frozen soil : permeability and structural effects due to freezing and thawing

    Författare :Peter Viklander; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Geoteknik; Soil Mechanics;

    Sammanfattning : This thesis is the result of the two projects:"Deformations in winter compacted soils" and "Permeability changes in a fine-grained till due to freeze/thaw". The aim of the first project was to study whether it is possible to compact frozen soils, in road embankments etc. LÄS MER

  7. 30. Rockfill Pavements on Soft Subsoil - Construction and Compaction

    Författare :Bo Johansson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Analytical or mechanistic design models are today available, which all require predictable material properties of the materials involved. However, the efficiency of compaction of pavements on soft subsoil is often questioned, since such pavements mostly show lower pavement quality and poorer performance, it seems like the full potential of the fill material not is utilised.
