    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.

    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

  4. 3. Cleaning of ultra-high temperature milk fouling -Structural and compositionl changes

    Författare :Carin Hagsten; Fysikalisk kemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Fouling is the deposit of proteins and minerals formed on equipment surfaces during the heat treatment of dairy products. The concentrations of the components and the structure of the fouling reflect the processing conditions used. The use of a higher processing temperature, e.g. LÄS MER
