    Abstract : 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.

  6. 4. Studies of the free mica properties and its influence on quality of road constructions

    Author : Dimitri Kondelchuk; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Geoteknik; Soil Mechanics;

    Abstract : The thesis presents series of laboratory studies of aggregates containing mica minerals obtained from aggregate producers located throughout Sweden. The main idea of the research was to study physical properties and behaviour of free mica particles in unbound granular products of crushed rock materials. READ MORE
