The invention relates to a bituminous coating comprising a material of low bulk density ranging between 0.01 and 0.3 t/min sufficient quantity to improve the acoustic performance thereof.

Bituminous coating with great acoustic performance

Described is the use, for preparing or treating bituminous compositions, of at least one compound selected among: esters of glycolic, lactic and gluconic acids, methylic, ethylic and isobutylic esters of glutaric, succinic and adipic acids, and ethers or esters of a product resulting from internal dehydration of a sugar, preferably a hydrogenated sugar. Also described is a method for preparing or treating such compositions and the resulting compositions.

Preparation and treating of bituminous compositions

The invention relates to a method for treating fumes generated during the production, conversion and/or handling of oil-based products and a device for carrying out said method. The invention further relates to the use of the method or device in which the trapping device comprises at least one fluidized bed of granular material in the preparation of a granular material for use in production of road materials.
