    Sammanfattning : The environmental, social and economic sustainability of our infrastructure network is clearly of paramount importance to the road-engineering sector as well to society at large. Sustainable road materials and reduced transport of those materials therefore play a significant role. LÄS MER

  2. 2. Fundamental investigation to improve the quality of cold mix asphalt

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

    Författare :Abdullah Khan; KTH.; [2016]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bitumen; Cold Asphalt Mixtures; Minerals Aggregates; Surface Free Energy; Sorption; Contact Angle; Bitumen Emulsions; Breaking and Coalescence.; Bitumen; kallblandad asfaltmassa; mineraler aggregat; fri ytenergi; sorption; kontaktvinkel; bitumenemulsion; brytning och blandning.; Transportvetenskap; Transport Science;

    Sammanfattning : Cold mix asphalt (CMA) emulsion technology could become an attractive option for the road industry as it offers lower startup and equipment installation costs, energy consumption and environmental impact than traditional alternatives. The adhesion between bitumen and aggregates is influenced by diverse parameters, such as changes in surface free energies of the binder and aggregates or the presence of moisture or dust on the surface of aggregates, mixing temperatures, surface textures (including open porosity), nature of the minerals present and their surface chemical composition, as well as additives in the binder phase.

  3. 3. Investigation of asphalt compaction in vision of improving asphalt pavements

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

    Författare :Ehsan Ghafoori Roozbahany; KTH.; [2015]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cold asphalt pavement joints; asphalt joint laboratory production; IDT joint evaluation; DTT joint evaluation; 4PB joint evaluation; joints FEM analysis. Discrete Element Modeling DEM ; X-ray Computed Tomography CT ; Compaction Flow Test CFT ; Compactability;

    Sammanfattning : Asphalt joints are potentially weakest parts of every pavement. Despite of their importance, reliable tools for measuring their mechanical properties for design and performance assessments are still scarce. LÄS MER
