Definitions
- the present invention relates to a process for preparing a bitumen-polymer composition.
- This composition can be stored and / or transported cold in an intermediate state and then converted into an application-ready composition having satisfactory elastic properties.
- the invention also relates to a kit consisting of a bitumen-polymer composition, in the form of bread, comprising a first additive and a capsule comprising a second additive, as well as the use of this kit in the process for the preparation of a composition bitumen-polymer according to the invention having satisfactory elastic properties.
- bitumen-polymer compositions have been used in the road sector and mainly for the manufacture of road pavements. These bitumen-polymer compositions have improved mechanical and rheological properties compared to conventional bitumen compositions, in particular they have elastic properties superior to those of conventional bitumen compositions.
- bitumen-polymer compositions are stored and transported hot, in bulk, in tanker trucks or by boats at elevated temperatures of the order of 120 ° C to 200 ° C.
- the storage and transport of hot bitumen has certain disadvantages.
- the transport of hot bitumen in liquid form is considered dangerous and it is very framed from a regulatory point of view. This mode of transport presents no particular difficulties when the equipment and the transport infrastructures are in good condition. Otherwise, it can become problematic: if the tanker is not sufficiently insulated, the bitumen may become viscous during a trip too long. Delivery distances for bitumen are therefore limited.
- the maintenance of bitumen at high temperatures in tanks or tank trucks consumes energy. In addition, maintaining the temperature of the bitumen for a given period can affect the properties of the bitumen, in particular due to aging phenomena and thus change the final performance of the asphalt.
- bitumen at ambient temperature in metal drums By way of example, mention may be made of the transport of bitumen at ambient temperature in metal drums. This means is increasingly questionable from an environmental point of view because the cold bitumen stored in the barrels must be reheated before use as a road binder. However, this operation is difficult to implement for this type of packaging and the drums are a waste after use. On the other hand, the storage of cold bitumen in drums leads to losses, because the bitumen is very viscous, and part of the product remains on the walls of the drum during the transfer of the bitumen to the tanks of the production units. As for handling and transporting bituminous products in these drums, they may be difficult and dangerous if specialized drum handling equipment is not available at the carriers or where the bitumen is used. In addition, the barrels used to transport the bitumen are not recovered again to transport the bitumen and therefore generate additional waste to be reprocessed.

- US patent application 2011/0290695 describes a system for dispensing and packaging bituminous products in block form.
- Each block of bitumen is surrounded by a film of bituminous composition consisting of about 10 to 30% by weight of natural bitumen and about 5 to 25% by weight of a synthetic rubber polymer.
- the bituminous composition film is melted with the bituminous product and is fully compatible with the molten bitumen.
- bituminous products packaged in the form of paper bags or of thermoplastic material can flow during their handling, storage and transport, because the bags or films made of thermoplastic material can be pierced, increasing the risk of deformation. and leakage, especially when the outside temperature is high.
- the bags or films of thermoplastic material are pierced, the bitumen flows and the bags or blocks surrounded by thermoplastic film stick together.
- the handling of the bags or blocks surrounded by thermoplastic material film thus deteriorated becomes impossible, which renders them unusable.
- US-4,332,704 discloses a bitumen composition formed by reacting a bitumen with a carboxylic acid or anhydride and a polyol.
- the resulting polyester modified bitumen may be crosslinked by means of a vulcanizing agent.
- US-4,338,231 discloses a bitumen composition formed by reacting a bitumen with a carboxylic acid or anhydride and a polyol, followed by reaction with a polyester and a vinyl aromatic monomer.
