  • Patent number: 9815983
    Abstract: Disclosed is a bituminous composition in the form of granules, each granule including a core and a coating and having a mass for approximately one hundred particles of from 0.5 g to 2 g, the core including from 40 wt. % to 60 wt. % of a binder matrix; from 30 wt. % to 40 wt. % of a polymer; from 4 wt. % to 6 wt. % of a compatibilizing agent; and from 2 wt. % to 15 wt. % of an anti-adhesive filler; and the coating including an anti-sticking agent. The invention relates also to a method for preparing the composition, and to the use thereof in bitumen plants.

  • Patent number: 8915995
    Abstract: The invention relates to coated material for the base layer of road pavement, made up of aggregate coated with a hydrocarbon binder, wherein the aggregate is more than 95 wt % of the coated material; wherein the aggregate includes a granular structure, which includes a plurality of granular fractions d/D; one intermediate fraction of which is less than 15% of the granules; wherein the hydrocarbon binder is less than 5 wt % of the coated material; wherein the coated material includes, after compacting, a void fraction of less than 8%; wherein the hydrocarbon binder is a hydrocarbon binder modified by adding polymers or oil, or modified by foaming or by emulsion, by means of which the modulus of rigidity of the coated material, once compacted, is higher than 9000 MPa.
