Definitions
- the present invention relates to a bitumen composition in divided form, solid at room temperature.
- the present invention also relates to a process for preparing a solid bitumen composition at ambient temperature and its use as a road binder, in particular for the manufacture of asphalt.
- the present invention also relates to a method for manufacturing asphalt from solid bitumen according to the invention and a method for transporting and / or storing and / or handling a solid bitumen composition at room temperature according to the invention. 'invention.
- bitumen used in construction, mainly for the manufacture of road pavements or in industry, for example for roofing applications. It is generally in the form of a highly viscous black material, even solid at room temperature, which becomes fluid upon heating.
- bitumen In general, bitumen is stored and transported hot, in bulk, in tanker trucks or by boats at high temperatures in the range of 120 ° C to 160 ° C.
- the storage and transport of hot bitumen have 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 viscosity of the bitumen may increase 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 bitumen at elevated temperatures for a long time may affect the properties of the bitumen and thus change the final performance of the bitumen.
- bitumen at room temperature in metal drums As an example of packaging for the cold transport currently used, there may be mentioned the packaging of bitumen at room temperature in metal drums. This means is increasingly questionable from an environmental point of view because the 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 bitumen at room temperature in drums leads to losses because the bitumen is very viscous and part of the product remains on the walls of the drum when transferring to the tanks of the production units of the mix. 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.

These bitumen granules allow the transport and / or storage and / or handling of the bitumen at room temperature without it flowing, as well as reducing their adhesion and agglomeration between them.

This The purpose of the coating layer is to prevent adhesion of the particles to each other, but also to adjacent surfaces during storage. This document does not disclose the content of viscosifying compound with respect to the total weight of the coating layer. It also does not disclose the viscosity of the compounds used in the composition of the coating layer.

After observing the solidification of the bitumen in the mold, the surplus is leveled with a heated blade Bunsen burner. After 30 minutes, the solid bitumen in the form of uncoated granules is demolded and stored in a tray covered with silicone paper. The cores are then allowed to cool to room temperature for 10 to 15 minutes.
