A scraper assembly for a construction machine includes a housing pivotally coupled to a frame of the construction machine for moving the scraper assembly between a stowed position and a deployed position. The scraper assembly also includes a scraper partially received within the housing. In the deployed position of the scraper assembly, the scraper engages with a machine component to remove material stuck to the machine component. The scraper assembly further includes a biasing device received within housing. The biasing device biases the scraper towards the machine component. Further, the biasing device travels in a substantially linear path for biasing the scraper towards the machine component.

A scraper used with a compactor wheel assembly includes an attachment portion, a scraping portion that forms a first oblique angle with the attachment portion, and a transition portion connecting the scraping portion to the attachment portion. The transition portion defines a stress concentrator for allowing the scraper to break before any structure to which the scraper is attached is damaged.

A scraper arrangement for a soil tilling roller of a soil tilling machine, comprising a scraper bar (32) which is elongated in the direction of a longitudinal bar axis (B) and is to be attached or is attached by means of at least two articulated units (40) to a machine frame (22) of a soil tilling machine (10) so that it can pivot between an active position and an inactive position, wherein each articulated unit (40) comprises a first articulated carrier element (42) intended to be fixed to a machine frame (22) and a second articulated carrier element (44) intended to be fixed to the scraper bar (32), characterised in that each articulated unit (40) further comprises at least one first articulated connection element (46), wherein the at least one first articulated connection element (46) is pivotably connected to the first articulated carrier element (42) about a first pivot axis (S.sub.1) in a first pivot coupling region (50) of the at least one first articulated connection element (46) and is pivotably connected to the second articulated carrier element (44) about a second pivot axis (S.sub.2) which is substantially parallel to the first pivot axis (S.sub.1) in a second pivot coupling region (54) of the at least one first articulated connection element (46), and comprises at least one second articulated connection element (48), wherein the at least one second articulated connection element (48) is pivotably connected to the first articulated carrier element (42) about a third pivot axis (S.sub.3) which is substantially parallel to the first pivot axis (S.sub.1) in a first pivot coupling region (60) of the at least one second articulated connection element (48) and is pivotably connected to the second articulated carrier element (44) about a fourth pivot axis (S.sub.4) which is substantially parallel to the third pivot axis (S.sub.3) in a second pivot coupling region (66) of the at least one second articulated connection element (48).

Ground compaction machine, which can be a rubber-tired roller, operable to compact ground in a working direction is presented, along with a wheel cover for the same. The machine can have a machine frame and a chassis supporting the machine frame. The machine frame having a front chassis portion and a rear chassis portion. At least one of the front chassis portion or rear chassis portion has at least two chassis units, each chassis unit being rotatable about a distinct steering axis. Each chassis unit having at least one wheel, and a wheel cover, which is formed for thermal insulation of the chassis units from the external surroundings, the wheel cover comprising at least two wheel cover units, and a wheel cover unit being arranged on each chassis unit, which is configured to be rotatable about the respective distinct steering axis together with the respective chassis unit.

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 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.

In some implementations, a controller may receive an input that indicates a proportion of a spray cycle in which a fluid spray system is to be active. The fluid spray system may include at least a first fluid pump configured to supply fluid to a first fluid spray bar and a second fluid pump configured to supply fluid to a second fluid spray bar. The controller may determine, in accordance with the proportion, a spraying timing for the first fluid pump and the second fluid pump that minimizes an overlap of an active time of the first fluid pump and an active time of the second fluid pump, and/or an overlap of an inactive time of the first fluid pump and an inactive time of the second fluid pump. The controller may cause activation of the first fluid pump and the second fluid pump in accordance with the spraying timing.

An electrically powered paving machine includes a hopper; a screed assembly; a conveying system; one or more batteries configured to power the electrically powered paving machine; a plurality of thermoelectric generators electrically connected to the one or more batteries; a potential thermal energy conversion device electrically connected to the one or more batteries; and processing circuitry. Additionally, the electrically powered paving machine controls charging the one or more batteries using electrical energy generated by one or more of the plurality of thermoelectric generators and the potential thermal energy conversion device.
