1. A civil engineering machine for spreading material for spreading on soils or base materials, having a container for material for spreading to receive the material for spreading, having a spreading arrangement having one or more outlet openings for the discharge onto a ground surface of the material for spreading, and having an anti-dust arrangement which is arranged below the one or more outlet openings of the spreading arrangement, characterized in that the anti-dust arrangement has one or more first anti-dust members which surround a spreading compartment arranged below the one or more outlet openings of the spreading arrangement, and one or more second anti-dust members which surround the first anti-dust members while forming an anti-dust space, both the first and the second anti-dust members being of a flexible form such that they are able to sweep along the ground surface. 2. The civil engineering machine according to claim 1, characterized in that the anti-dust arrangement has a suction extractor arrangement for extracting dust from the anti-dust space. 3. The civil engineering machine according to claim 2, characterized in that the suction extractor arrangement has a collecting container for dust. 4. The civil engineering machine according to claim 3, characterized in that suction extractor arrangement has a means for transferring the dust collected in the collecting container to the container for material for spreading. 5. The civil engineering machine according to claim 1, characterized in that the anti-dust arrangement has a spraying arrangement for spraying the anti-dust space with a liquid. 6. The civil engineering machine according to claim 5, characterized in that the spraying arrangement has a duct having spray nozzles which is arranged in the anti-dust space. 7. The civil engineering machine according to claim 5, characterized in that the liquid for spraying the anti-dust space has admixed with it an additive for binding the dust or causing it to settle. 8. The civil engineering machine according to claim 7, characterized in that the additive for binding the dust or causing it to settle is an additive for forming foam. 9. The civil engineering machine according to claim 1, characterized in that the anti-dust space is a space which surrounds the spreading compartment. 10. The civil engineering machine according to claim 1, characterized in that the first and/or second anti-dust members are members made at least partly of a flexible material which form a skirt. 11. The civil engineering machine according to claim 1, characterized in that the one or more first anti-dust members bounding the spreading compartment comprise front anti-dust members which are at the front in the direction of travel and rear anti-dust members which are at the rear in the direction of travel and lateral anti-dust members which extend in the longitudinal direction of the civil engineering machine. 12. The civil engineering machine according to claim 1, characterized in that the one or more second anti-dust members bounding the anti-dust space comprise front anti-dust members which are at the front in the direction of travel and rear anti-dust members which are at the rear in the direction of travel and lateral anti-dust members which extend in the longitudinal direction of the civil engineering machine. 13. The civil engineering machine according to claim 1, characterized in that the civil engineering machine is a non-self-propelled civil engineering machine for spreading binders for soil or base material stabilization which can be mounted on a drawing vehicle, or which can be towed by the drawing vehicle. 14. The civil engineering machine according to claim 1, characterized in that the civil engineering machine is a stabilizer or recycler which has a rotor for milling up the soil or base material and mixing in the material for spreading. 15. A spreading apparatus for spreading material on a ground surface, comprising: a material container for the material;a spreader connected to the material container, the spreader having one or more outlet openings through which the spreader can discharge the material from the material container, the one or more outlet openings being arranged such that the material freely drops from the one or more outlet openings onto the ground surface without contacting another structure;an inner skirt including one or more inner skirt members extending downward below the one or more outlet openings of the spreader sufficiently close to the ground surface to define a spreading compartment below the one or more outlet openings to retain dust which arises when the material drops from the one or more outlet openings onto the ground surface, the spreading compartment being at least partly surrounded by the inner skirt; andan outer skirt including one or more outer skirt members, the outer skirt at least partly surrounding the inner skirt and defining a peripheral space between the inner skirt and the outer skirt to further retain dust which escapes from the spreading compartment, the one or more outer skirt members being made at least partly of a flexible material such that the one or more outer skirt members are able to sweep along the ground surface. 16. The apparatus of claim 15, further comprising: a suction extractor communicated with the peripheral space so that the suction extractor can extract dust from the peripheral space. 17. The apparatus of claim 16, further comprising: a collecting container communicated with the suction extractor to collect the dust extracted by the suction extractor. 18. The apparatus of claim 17, further comprising: a transfer passage communicating the collecting container with the material container so that dust collected in the collecting container can be returned to the material container. 19. The apparatus of claim 16, further comprising: a spraying system communicated with the peripheral space and arranged to spray a liquid into the peripheral space. 20. The apparatus of claim 15, further comprising: a spraying system communicated with the peripheral space and arranged to spray a liquid into the peripheral space. 21. The apparatus of claim 20, wherein the spraying system comprises a duct and a plurality of spray nozzles. 22. The apparatus of claim 20, wherein the liquid includes a binding additive for binding dust in the peripheral space. 23. The apparatus of claim 22, wherein the binding additive includes a foaming agent. 24. The apparatus of claim 15, wherein the peripheral space completely surrounds the spreading compartment. 25. The apparatus of claim 15, wherein the one or more inner skirt members are made at least partly of a flexible material extending downward to sweep along the ground surface. 26. The apparatus of claim 15, wherein: the spreading compartment is completely surrounded by the inner skirt, and the inner skirt includes one or more front inner skirt members, one or more rear inner skirt members, and one or more longitudinal inner skirt members along each of two opposite longitudinal sides of the spreading compartment. 27. The apparatus of claim 15, wherein: the outer skirt includes one or more front outer skirt members, one or more rear outer skirt members, and one or more longitudinal outer skirt members along each of two opposite longitudinal sides of the peripheral space. 28. The apparatus of claim 15, wherein the spreading apparatus is a non-self-propelled apparatus for spreading binders for soil or base material stabilization, and includes a mount for attachment of the apparatus to a drawing vehicle. 29. The apparatus of claim 15, wherein the spreading apparatus comprises a stabilizer or recycler including a rotor for milling up the ground surface and mixing in the material from the material container.
