- planer is a self-propelled machine on lateral tracks, the casing of the planing-milling tool being arranged under the machine, between the lateral caterpillars,
- the aqueous composition comprises an emulsion of bitumen, its temperature being approximately 60 ° centigrade,
- bitumen emulsion is dosed with a determined percentage of ad hoc bitumen, the bitumen foam introduced into the casing is hot, its maximum temperature being approximately 1 60 ° centigrade and its minimum temperature being approximately 100 ° C. centigrade,
- each additive water forming the aqueous composition is stored in a reservoir of the planer, said aqueous composition being stored ready for use,
- the or at least one of the reservoirs of the planer is a buffer tank and is connected by a supply hose to said buffer tank to an external transport tank which follows or precedes the planer during its displacement,
- a water misting is implemented at least within the casing of the planer and at the level of the fairing of the planer,
- the misty water in the casing of the planer and at the level of the fairing of the planer comprises at least surfactants and / or mineral and / or organic fillers, the aqueous solution comprising mineral and / or organic fillers is also spread, in particular misted, on the outer periphery of the planer fairing,
- a recuperation and evacuation member is also implemented outside the casing of the aggregates produced, said member comprising an inclined endless conveyor belt carrying said aggregates from an upstream end, on the caster side of the planer, to a downstream end; next to a storage element into which said produced aggregates fall,
- the misty water for the treadmill member comprises at least surfactants and / or mineral and / or organic fillers,
- a drop chute for the aggregates is disposed at the downstream outlet of the treadmill member
- the chute chute is extended downwardly to pass through a filling opening of the storage element.

- the aqueous composition is chosen alone or in a chemically compatible physical combination among: a bitumen emulsion, a bitumen foam, an aqueous solution comprising mineral and / or organic fillers.
- asbestos-containing asphalt planing methods lead to a fiber emission measured in the META method at a level 1 of between 30 and 50 fibers per liter of inhaled air. Thanks to the invention, it is possible to go to a level of less than 5 fibers per liter of inhaled air, and possibly less by adding other barriers to the emission of dust.
- the invention consists in introducing water with one or more types of dust stabilizing agents in the form of an emulsion of bitumen, bitumen foam or an aqueous solution containing mineral and / or organic fillers.
- the bitumen foam and the bitumen emulsion are aqueous compositions in the context of the invention because they comprise water.
- the tool is conventionally a planing drum. This added water may also be emitted on the outer periphery of the planer and, in this case, it will preferably be in the form of an aqueous solution containing mineral and / or organic fillers.
- the method may use one, two or even three types of stabilizers.

It comprises a casing 2 in which is disposed transversely a planing-milling tool 3 provided with teeth that tear loads from the initial floor 4, which generates dust. This dust is removed by introducing into the crankcase aqueous compositions for agglomerating the dust with the produced costs to form aggregates 5 which will then be taken up by a conveyor belt 10 for recovery in a storage means 1 1 which is here a skip transport of a semi-trailer. Downstream of the planer, if one considers its direction of travel shown schematically by an arrow in Figure 1, the pavement is planed 4 '.
