  • Performance modifiers for bitumen comprising straight and branched chain fatty amide waxes
    Patent number: 9493633
    Abstract: The present invention generally relates to the discovery that a blend of linear and branched amide wax additives can be used to enhance the performance of asphalt binders and asphalt emulsion residues. In particular, high temperature properties of asphalt pavement can be improved while maintaining or improving low temperature properties. The additives also improve workability and lower processing temperatures for asphalt paving (e.g. warm mix) or for roofing. These amide wax additives can reduce the tracking of tack coats, by decreasing binder penetration and forming a non-tacky surface layer.

    Patent number: 9321150
    Abstract: Aggregate abrasive grains for use in the production of abrading or cutting tools are formed such that each grain includes an abrasive core particle and a plurality of abrasive peripheral particles disposed around the core particle. The abrasive particles intended as the core particles are provided with a coating containing a binder. These binder-coated core particles are then surrounded with those particles that are intended to become the peripheral particles of the aggregate grains. The binder-coated core particles surrounded with the peripheral particles are heated to a temperature at which the binder softens so that the peripheral particles attach to the core particles.
