A system and method for recycling used asphalt material through convection heating and gentle tumbling recycles used asphalt material, such as reclaimed asphalt pavement, by uniformly and gradually applying radiant and convectional heating towards the used asphalt material. A radiant heating coil generates a controlled amount of radiant heat, at about 325 degrees, and up to 750 degrees Fahrenheit. At least one blower works to blow the radiant heat to the used asphalt material as convectional heat. An agitating conveyor simultaneously carries the used asphalt material while it is being heated. The agitating conveyor has a radiant heated conveyor floor that comprises depressions that work to agitate the used asphalt material. The uniform heating of the used asphalt material inhibits moisture from surging from the used asphalt material and maintains integrity of the subsequently formed rejuvenated asphalt. A rejuvenating chamber mixes the used asphalt material with a rejuvenating composition.

A mobile asphalt plant for producing asphalt includes a heating unit, a container unit, a plurality of augers, and an injector. The heating unit includes one or more heaters to generate heated gas, a tank to hold heat transfer oil, and one or more first plenum tubes extending from the heaters to within the tank. The first plenum tubes transport the heated gas to the tank to heat the heat transfer oil. The container unit includes a hopper to receive the aggregate material and one or more second plenum tubes extending from the one or more first plenum tubes and extending within the hopper. The second plenum tubes transport the heated gas from the first plenum tubes to heat the aggregate material. The augers are arranged as a series of augers, with a first one of the augers receiving the aggregate material from the hopper. Each of the augers conveys the aggregate material to a next one of the augers. Each of the augers heats the aggregate material using the heat transfer oil from the tank. The injector is connected to one of the augers and injects asphalt oil into the aggregate material to produce asphalt.

A pavement striping devices for heating and applying thermoplastic material to a road surface is provided. The pavement striping device includes of: a hopper for holding a supply of particulate thermoplastic marking material in a non-molten state, an air or oil-heat transfer medium melting kettle having a series of coaxial conveyored or unconveyored conduits within, a plastic extruder for transporting the thermoplastic particulate from the hopper to the series of coaxial conveyored or unconveyored conduits with the air or oil-heat transfer medium melting kettle, a heating mechanism for heating the air or oil-heat transfer medium melting kettle and the plastic extruder to a temperature suitable for melting thermoplastic, and a means for driving the stream of molten thermoplastic through the series of coaxial conveyored or unconveyored conduits to a sprayer or extrusion die, all of which form a means by which the molten thermoplastic is directed to the pavement surface.

The present disclosure refers to the development of a hot mix asphalt plant mounted on a single fixed chassis with the correct dimensions for transport in a single shipping container. On this tubular structure chassis, two individual dosing silos fixed to the chassis and supported on metering conveyor, a rotary dryer, a two-axle pug mill mixer, an enclosed burner, a fuel pipe, bituminous binder tubing, exhaust pipe, bag filter, drag lift and a control cabin are disposed.

A method of mixing a crosslinking blend in a portable tote for use to crosslink polymer modified asphalts. The method includes providing a portable tote, where the tote includes a tank having a sidewall, a top and a bottom portion. Fixedly positioned partially within the tank interior is an air mixing system that includes a hollow wand that has a distal and a proximal end. The proximal end of the wand exits the tank. The distal end of the tote is connected to at least one accumulator plate, where the accumulator plate is adjacent to the interior bottom portion of the tank. Stored in the interior of the tank is a crosslinking blend suitable for use to crosslink polymer modified asphalts. The method includes the steps of attaching a pulsed gas controller to the proximal end of the wand and coupling a source of compressed gas to the controller, then activating the controller to cause mixing of the crosslinking blend by pulsing gases into the crosslinking blend for a sufficient period of time. After, or during mixing, the crosslinking blend is discharged from the interior of the tank, and the controller is removed from the wand, leaving said wand attached to the tank.

A flame protection apparatus for a burner, in particular in a drying drum, in particular in an asphalt facility, comprises a central longitudinal axis and a plurality of lifter plates, which are arranged in the circumferential direction with respect to the central longitudinal axis, wherein at least one plate fin holder for holding a plate fin is detachably fastened to each of the lifter plates.

A method produces a composite material using a mixing system. The composite material comprises at least one aggregate, e.g. rock and/or glass, and the reaction product of a two-component polymeric binder composition comprising a first component, e.g. an isocyanate component, and a second component, e.g. an isocyanate-reactive component. The mixing system includes a mixing apparatus. The method includes the step of providing the aggregate, the first component and the second component into the mixing apparatus. The method further includes the step of mixing the first and second components to produce the reaction product of the two-component polymeric binder composition, and the step of applying the reaction product of the two-component polymeric binder composition to the aggregate within the mixing apparatus to produce the composite material. The composite material can be used for forming a paved structure, such as a sidewalk or a roadway.
