Civil engineering machine for spreading material for spreading on soils or base materials

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;
• and
• an 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.
