The present invention proposes a roller for asphalt compaction, in particular a rubber tire roller, comprising: a rubber tire, a spray device for spraying a rubber tire with a separation agent mixture composed of a first liquid and a second liquid, a first tank for the first liquid and a second tank for the second liquid, characterized in that the rubber tire roller, in order to form the separation agent mixture, comprises a mixing device for mixing the first liquid supplied by the first tank and the second liquid supplied by the second tank. Further, the present invention relates to a method for spraying a rubber tire of a roller for asphalt compaction with a separation agent mixture.

A processing apparatus is used for surface treatment of undried concrete. The processing apparatus comprises a main body portion placed on the undried concrete; a first roller provided on a bottom portion of the main body portion; a second roller provided on a back side of the first roller on the bottom portion and arranged in parallel to the first roller; a driving portion mounted on the main body portion and configured to give a rotational driving force to the first roller and the second roller; and a handle portion protruded forward from the main body portion to be held by an operator who stands in front of the main body portion. The first roller and the second roller are configured to idle in such a state that the first roller and the second roller come into contact with a surface of the undried concrete by the rotational driving force of the driving portion, when the operator holds the handle portion to move the main body portion forward.

A method for compacting asphalt material (A) by means of at least one soil compactor (10) having at least one compactor roller with a motion generation arrangement assigned to the same, comprising the measures: a) detection of an asphalt temperature of the asphalt material (A) to be compacted, b) static compaction of the asphalt material (A) with a deactivated motion generation arrangement of the at least one compactor roller, if the asphalt temperature lies above an upper threshold temperature (O), c) static compaction of the asphalt material (A) with a deactivated motion generation arrangement of the at least one compactor roller, if the asphalt temperature lies below a lower threshold temperature (U),
wherein the upper threshold temperature (O) and/or the lower threshold temperature (U) is/are set depending on at least one surroundings parameter (T) influencing the cooling behavior of the asphalt material to be compacted.

Described herein is a process for paving a surface with an asphalt paving material, comprising the steps of laying asphalt paving material on a surface to be paved; and combining an asphalt rejuvenator and the asphalt paving material; wherein the asphalt rejuvenator and the asphalt paving material are combined immediately before, concurrently with, or immediately after the asphalt paving material is laid on the surface to be paved. The asphalt paving material may be virgin asphalt, or it may comprise reclaimed asphalt pavement and/or recycled asphalt shingles.

A compactor includes a compactor structure and at least one roller unit rotatably supported on the compactor structure about a roller axis of rotation. A roller heater is deployed in assignment with at least one roller unit. The roller heater is a liquid fuel-operated heating device with a burner region, a fuel pump for supplying liquid fuel from a fuel tank to the burner region and a combustion air blower for supplying combustion air to the burner region.

A working machine, movable on a substrate, comprises a sensor arrangement, wherein the sensor arrangement comprises: at least one sensor housing (24) with a sensor accommodation space (26) open via a detecting aperture (30), at least one sensor (28) arranged in the sensor accommodation space (26) of the at least one sensor housing (24), at least one air-supply arrangement (32) for generating an air flow (L) flowing through the sensor accommodation space (26) in the at least one sensor housing (24).

A fluid spray system for a compaction machine is provided. The fluid spray system includes at least one nozzle adapted to deliver a flow of fluid adjacent to a compaction member. The fluid spray system includes a fluid pump adapted to provide the flow of fluid to the at least one nozzle. The fluid spray system includes an operator interface configured to generate a signal indicative of activating a test mode based on an operator input. The fluid spray system includes a controller configured to receive the signal from the operator interface. The controller is also configured to activate the fluid pump for a predefined time period to provide the flow of fluid to the at least one nozzle. The controller is further configured to deactivate the fluid pump based on elapsing of the predefined time period to limit the flow of fluid to the at least one nozzle.

A compactor includes a compactor structure and at least one roller unit rotatably supported on the compactor structure about a roller axis of rotation. A roller heater is deployed in assignment with at least one roller unit. The roller heater is a liquid fuel-operated heating device with a burner region, a fuel pump for supplying liquid fuel from a fuel tank to the burner region and a combustion air blower for supplying combustion air to the burner region.

A tire skirt support assembly for a compactor comprising a bracket and one or more skirt support members. The bracket can be oriented horizontally, and each skirt support member can have a body that is elongate with a first end and a second end opposite the first end. For each said skirt support member, the first end can be fixed to the bracket, and the second end can be below the bracket and is a free end configured to removably engage a skirt via an attachment opening in the skirt.

A rubber-tired roller for the compaction of a ground, in particular for asphalt compaction, with a machine frame, a drive engine, a chassis driven by said drive engine with a front chassis part and a rear chassis part, at least one chassis part comprising at least two tires with running surfaces, which are arranged next to one another, at least one sprinkler system for the tires of the chassis part, which is configured to apply a liquid separating agent to the running surfaces of the tires, and a control unit for controlling the sprinkler system, wherein a temperature sensor is provided which is configured and arranged such that it determines the temperature of at least one tire, in particular the running surface of said tire. The invention moreover relates to a method for controlling a sprinkler system of such a rubber-tired roller.
