Abstract: The present disclosure relates to the field of so-called “spreading” emulsions of hydrocarbon binder, in particular cationic emulsions of hydrocarbon binders. Such emulsions are useful in the preparation of surface dressings, tack coats, fog seal type surface courses and paver seams. The use of an anionic polymer to improve immediate adhesiveness of a cationic emulsion of hydrocarbon binder to solid particles is particularly described.

Abstract: A process for preparing a cationic latex modified hydrocarbon binder emulsion comprising the steps of: (a) preparing a cationic copolymer latex emulsion by an emulsion polymerisation of polymerizable monomers, said polymerizable monomers comprising A—one or more non-ionic acrylate ester and/or methacrylate ester monomer(s), and B—optionally styrene monomer and/or one or more non-ionic styrene derivative monomer(s), C—optionally one or more cross-linking monomer(s) having two or more ethylenically unsaturated (C?C) double bonds susceptible to free radical copolymerisation, D—optionally one or more epoxy functional monomer(s) having one C?C double bond susceptible to free radical copolymerisation and one epoxide functional group, wherein said polymerizable monomers do not comprise any aliphatic conjugated diene monomer, in presence of a cationic stabilizing surfactant, and (b) adding the cationic copolymer latex emulsion resulting from step (a) to a cationic hydrocarbon binder emulsion, or (b?) adding the catio

Abstract: The present patent application concerns the use of at least one compound of formula (I): R1—O—C(O)—R2??(i) in which: R1 is a linear or branched C1-C6 alkyl group, and R2 is a linear or branched hydrocarbon chain comprising from 2 to 13 carbon atoms and one or more unsaturations, the said unsaturation(s) being one or more carbon-carbon double bonds, as a fluxing agent for hydrocarbon binders.

Abstract: A method for freezing and treating a mass of soil, making it possible to compensate for deformations of the mass of soil during thawing, including the following steps: a) producing at least one bore (2) in the mass of soil, b) at least partly freezing the mass of soil using a freezing fluid injected into the bore, and then c) injecting a compensation grouting into the mass of soil, using the bore (2) that was used for freezing, during the thawing phase in order to at least partly compensate for variations in the volume of the mass of soil when the latter thaws.

Abstract: A transport installation includes a traction member extending in a circuit and associated with an external power source so as to be moved along the circuit, a vehicle having a power storage system, a motor system, a generator system and a fixed support adjacent to the circuit. The generator system of the vehicle includes a generator that may be activated to supply power to the storage system when the vehicle is coupled to the traction member and driven along the circuit by the traction member. The motor system of the vehicle includes a motor that may be activated to receive power from the storage system and move the vehicle relative to the fixed support.

Abstract: Underground distribution system for the distribution of goods in an urban environment including at least one micro-tunnel forming at least one loop, extending under the foundations of preexisting surface buildings and/or infrastructures, in which goods, the transportation of which is automated, circulate, and a plurality of exchange stations exchanging with the surface, each including a shaft allowing goods to be lowered down to the micro-tunnel and raised back up after they have been transported within the micro-tunnel.

Abstract: The method involves projecting layout information on a working surface of a construction work. The projected layout information is obtained from a model, such as a Building Information Model (BIM), of a portion at least of the construction work. It includes first graphical information depicting a reference feature visible on the working surface, and second graphical information designating locations for installation of construction elements. The locations are linked, in the model, to the reference feature depicted by the first graphical information. In response to a user action of selecting the first graphical information and a geometric transformation, the projected first graphical information and second graphical information are shifted together in accordance with the selected transformation.

Abstract: A facade or roof element (10), in particular a window, comprising: at least one glazing unit (20); at least one electro-reactive element (22) having optical transparency and/or light-filtering properties that are electrically controllable, and which at least partially overlaps with the glazing unit; at least one photovoltaic panel (32), offset relative to the glazing unit, and providing at least part of the electrical energy required to power the electro-reactive element (22).

Abstract: A building façade or roof comprising at least one photovoltaic element and at least one microwave relay powered at least in part by the electricity generated by the photovoltaic element.
