The present invention provides a method for preparing a hot-mixed asphalt mixture, and relates to the technical field of road engineering. In the present invention, asphalt and aggregates are preheated separately, where the aggregates include coarse aggregates and fine aggregates; the coarse aggregates, part of the fine aggregates and asphalt that are preheated are subjected to a first mixing to obtain a first mixture; the remaining fine aggregates are added to the first mixture for a second mixing to obtain a second mixture; and a mineral powder is added to the second mixture for a third mixing, and discharging is conducted to obtain a hot-mixed asphalt mixture.

An onsite computer system can be located at a material production facility and used to generate tickets associated with the transfer of bulk materials such as asphalt or concrete. A remote computer system can communicate with the onsite computer system and can be used to generate ticket templates and configuration files that may be uploaded to the onsite computer system. In addition, the remote computer system can access the onsite computer system to edit system software or perform other corrective actions in the event there are any errors with the onsite computer system.

The invention relates to a mixing device adapted to manufacture bituminous mixes comprising: at least one means for conveying at least one granulate, such as a recycled aggregate, towards a malaxator and/or a drying drum, said conveyor means having an upper face adapted to receive the granulate, several groups of infrared emitter(s), disposed in line with said upper face of said at least one conveyor means and which are adapted to emit a wavelength which substantially corresponds to the maximum wavelength in the determined absorption spectrum of said at least one granulate at a desired temperature, each group of infrared emitters being adapted to emit a specific wavelength which is different for each group, said at least one conveyor means being adapted to and/or configured so as to withstand the electromagnetic radiations emitted by said groups of infrared emitters.

The invention also relates to the method for implementing the aforementioned device, as well as uses thereof.

A storage silo apparatus having a storage silo including a shell wall, a secondary wall spaced radially outwards from the shell wall, and a space having a first width formed between an outer surface of the shell wall and an inner surface of the secondary wall. An insulation layer located in the space is narrower than the space such that an air gap is formed within the space. The air gap is formed radially adjacent the insulation layer and is configured to resist heat transfer between the shell wall and the secondary wall.

The present invention relates to a bitumen composition comprising a petroleum slack wax and a Fischer-Tropsch wax, the use of the waxes in bitumen compositions, the use of the bitumen composition in asphalt compositions, asphalt compositions comprising the bitumen composition and a method for producing asphalt pavements and constructions thereof. The bitumen has proved to have better processing characteristics.
