    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.

  4. 18. NMR Studies of Gel-Emulsions; Diffusometry and Applications of Novel Field Gradient Techniques

    Författare :Carin Malmborg; Fysikalisk kemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; modulated gradients; imaging; Physical chemistry; Fysikalisk kemi; NMR; emulsion; diffusion;

    Sammanfattning : The aim of these studies has been to investigate what information that can be obtained on gel-emulsions with nuclear magnetic resonance, NMR, as the investigating tool. The gel-emulsions are important in many technical applications such as in food products, in cosmetic and pharmaceutical formulations, and in emulsion explosives, just to name a few applications.
