Methods of forming an asphalt shingle waste powder from asphalt shingle waste
Non-limiting embodiments of the present disclosure relate to a method comprising: obtaining asphalt shingle waste (ASW) and performing grinding, screening, and separating steps on the ASW. In some embodiments, granules are removed from the ASW. In some embodiments, the method transforms ASW into ASW powder. In some embodiments, the ASW powder is formed into a plurality of briquettes. In some embodiments, at least one of: the ASW powder, the plurality of briquettes, or any combination thereof is fed into a mixing process that results in an ASW powder filled coating.
Asphalt mixing plant
An asphalt mixing plant includes several transportable modules, each module being formed by a normalized transport container in which at least one of the primary pieces of equipment of the asphalt mixing plant is incorporated, the primary equipment being installed permanently in the container while being mounted stationary in the container or mounted movable in the container between a transport position and a usage position, at least one of the modules including a placement device incorporated into the container and configured to position the container as a whole relative to the ground and/or to position a movable primary piece of equipment in the usage position relative to the container.

Method and apparatus for recycling asphalt milings
Apparatus and method for recycling asphalt millings containing bitumen and stone. A milling tube is provided having an outer tube and an inner tube axially aligned with and substantially contained within the outer tube, the inner tube having a diameter less that a diameter of the outer tube to thus define a mixing space between the inner and outer tubes. At least one of the inner and outer tubes is adapted to rotate relative to the other. An inlet is provided to the mixing space to receive the asphalt millings. A plurality of inner tube projections project radially outward from a surface of the inner tube toward the outer tube, and a plurality of outer tube projections project radially inward from a surface of the outer tube toward the inner tube. The milling tube facilitates the separation of the asphalt millings into bitumen and stone as one of the inner and outer tubes rotates relative to the other. Preferably, at least one of the outer and inner tubes contains an abrasive coating on a surface thereof, the inner tube projections and outer tube projections are comprised of wire rope, and an inlet is provided in the outer tube through which cold air can be applied to the mixing space.
DEVICE FOR COATING AGGREGATES, METHOD AND USES
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.
