Abstract: The invention concerns a composition for producing a running surface layer or capping layer, in particular for roads or industrial floors. The composition includes a non-modified bitumen emulsion, a hydraulic binder, aggregates and optionally water. The composition has hydraulic binder content C1 between 12 wt. % and 30 wt. % relative to the total weight of the dry constituents of the composition; the ratio R1 of the sum of bitumen volumes and hydraulic binder over the volume of aggregates ranges is between 20% and 150%; and the non-modified bitumen emulsion is at least a non-ionic surfactant. A method for preparing the composition and its use for producing a running surface layer or capping layer is also disclosed.

Abstract: The invention concerns an aqueous bitumen emulsion, consisting of the following constituents expressed in weight percentages of the emulsion total weight: 50% to 70% of bitumen; 0.5% to 10% of surfactant; 0% to 5% of thickening agent; 0% to 1% of antifoaming agent; a sufficient quantity of water to make up 100%. Said emulsion is characterised in that the surfactant consists of at least a surfactant selected among the group consisting of an ethylene oxide and a propylene oxide copolymer, with PO/EO ratio ranging between 1.5 and 10, an ethoxylated and/or propoxylated epoxidized surfactant, and a polyvinyl alcohol having molecular mass ranging between 10000 and 150000. The invention also concerns the method for obtaining said emulsions, the compositions containing them, and the use of said bitumen emulsions for the formulation of compositions comprising a hydraulic or organic binder, and/or a mineral or organic filler.
