LAIT DE COMPOSE CALCO-MAGNÉSIEN POUR MATÉRIAU ROUTIER BITUMINEUX
The invention concerns the use of an aqueous suspension of solid particles of a calcium/magnesium compound of formula (A): nCa(OH)2.mCaCO3.aMgO.bMg(OH)2.cMgCO3.I as an agent regulating the breaking of a bitumen emulsion. The invention also concerns a bituminous road material obtained by mixing a solid mineral fraction with a cationic bitumen emulsion of the type binder in water, characterised in that it involves adding, to the mineral fraction, an aqueous suspension of solid particles of a calcium/magnesium compound of formula (A). The invention also concerns a method for preparing a material according to the invention and the use of same for producing surface courses, tack coats or temporary surface courses. The invention finally concerns a method for obtaining a tack coat by spreading a cationic bitumen emulsion, comprising a step of applying an aqueous suspension of solid particles of a calcium/magnesium compound of formula (A).
