The invention concerns a method (100) for recovering and/or recycling a bituminous product by means of pulsed power, the bituminous product comprising bitumen and elements to be separated, involving the following steps: —supplying (101) a reactor (11) inside which at least two electrodes (13) extend with the bituminous product and a liquid medium of which at least one liquid component has Hansen solubility parameters δη, δρ and δd such that the bitumen is at least partially soluble in the liquid medium, the elements to be separated being insoluble, —generating (102) a series of electromagnetic pulses between the electrodes (13) in the reactor (11) so as to produce, as a result of the power, the frequency and the switching time of the electromagnetic pulses, at least one shock wave and at least ultraviolet radiation, in such a way as to disperse and dissolve the bitumen in the liquid medium, and to separate the bitumen and the insoluble elements, the liquid medium preventing the reconstitution of the bitumen.

A method of determining optimal frequency to load haul trucks can include a central controller receiving an indication of the amount of paving material at a paving machine, and an indication of production rate of the paving machine. The central controller can then determine when more paving material should be provided to the paving machine. Based on this determination, the central controller can provide alerts or triggers to a paving material plant to indicate when haul trucks should be loaded to provide additional paving materials to the paving machine.

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, comprising a mixing drum and a temperature monitoring system, the temperature monitoring system comprising a temperature sensor configured for contactless measurement of a material temperature of an asphalt mix to obtain at least a first temperature value for at least a first point of time, where the temperature sensor is arranged at an area of an output of the mixing drum or at a discharge chute of the mixing drum; and an operation and monitoring unit and a remote server; whereby the operation and monitoring unit is configured to wirelessly transmit the at least first temperature value to the remote server via a wireless communication interface unit.

Applicator and method for applying melted rubber to pavement comprises a melting vat having a substantially planar bottom with a surface area, and a wide-area a heating element beneath the melting vat having a surface area more than half the surface area of the planar bottom of the melting vat and positioned beneath the melting vat. The heating element may be comprised of an aluminum oxide ceramic blanket. A double-walled construction of the vat with exhaust holes in the outer wall allows exhaust to evenly melt rubber in the vat to reduce burning of the rubber, flame blowouts, and improve fuel efficiency.

Asphalt production facility and method for making asphalt in such an asphalt production facility

The invention relates to an asphalt production facility (1) comprising: a drum dryer (3), a combustion chamber (9), a burner (11) configured to generate a hot gas flow (F1) circulating in the drum dryer (3), at least one first device (13) for the introduction of asphalt aggregates to be recycled that defined at least one recycling area (15), a cooling channel (17) defined between a wall (19) of the combustion chamber (9) and an external envelope (30′) of the drum (3), a device (21) for injection of a cooling fluid (F4) into the cooling channel (17), and a control and regulation system (23) for piloting the injection device (21) in such a way that the hot gas flow (F1) has a temperature that is lower than 700° C. in said recycling area (15).

A method for making asphalt in such asphalt production facility.

An inner drum for use in a dryer/mixer in connection with the production of an aggregate-binder mix includes a plurality of mixing paddles disposed on the outer surface of the inner drum and arranged in a plurality of rows. The mixing paddles are configured to rotate through a mixing chamber as the inner drum rotates within an outer drum of the dryer/mixer to mix aggregate and binder together. Interstitial spaces are formed between rows of mixing paddles and material leads, where aggregate material preferentially travels as the inner drum is rotated, extend along the mixing chamber. At least one interstitial mixing paddle is located on the outer surface of the inner drum and in one of the interstitial spaces at one of the material leads. The interstitial mixing paddle rotates through the mixing chamber as the inner drum rotates to also mix the aggregate and binder together.

A system for producing hot mix asphalt includes a generator having an exhaust port; a dryer drum having an inlet; a duct connecting the exhaust port to the inlet, the duct conveying a first flow of hot gas from the exhaust port; an exhaust bypass vent conveying a second flow of hot gas diverging from the first flow of hot gas; and a valve disposed at a junction between the duct and the exhaust bypass vent for adjusting a flow rate of the second flow of hot gas. The dryer drum produces hot mix asphalt from asphalt materials using a third flow of hot gas diverging from the first flow of hot gas and entering the dryer drum through the inlet.
