A road finisher is provided for producing a paving layer on a subgrade on which the road finisher is movable along a paving direction during a paving run. The road finisher is adapted to use distance measurements to the subgrade, which can be provided to a leveling system of the road finisher, equally as measured values for determining the thickness of a layer. A respective method for determining the layer thickness is provided.

A limiting plate of a road paver is detachably attached to a traverse or to a chassis of the road paver to increase the basic working width. The limiting plate is arranged with variable spacing to a subgrade. In order to prevent a mix from flowing forwards in a direction of travel and at the same time improve the efficiency of a screw conveyor, in which a geometrically defined screw trough is formed, a limiting plate extension is arranged on the limiting plate so that it can be adjusted, particularly in the direction of the subgrade.

A strike off assembly for a placer spreader apparatus includes a strike off support beam and left and right side plate assemblies attached to ends of the support beam. A strike off plate assembly includes a left strike off plate portion and a right strike off plate portion pivotably connected together. A plurality of strike off actuators are connected to the strike off plate assembly and configured to raise and lower the strike off plate assembly relative to the support beam to vary a height of a material placement space.

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.

This disclosure relates to an adjustable paving machine. In some examples, the adjustable paving machine includes a variably expandable portion. The variably expandable portion may be expandable laterally such as to accommodate paving operations of variable widths. The adjustable paving machine may be configured to spread a variety of paving materials on a paving surface, including oils, emulsions, asphalt, slurries, or the like. The adjustable paving machine may include a containment basin operative to contain a paving material such as to reduce lateral or longitudinal movement of the paving material. The adjustable paving machine may include an adjustable shoe configured to move the paving machine vertically relative to the paving surface. The adjustable paving machine may include one or more spreading elements configured to spread the paving material on the paving surface. The spreading elements may be supported by a spreading element support enabling easy replacement of the spreading elements.

An adjustable paving machine includes a first frame portion having a plurality of walls, and a variably expandable portion having a plurality of walls and being operably coupled to the first frame portion. The adjustable paving machine also includes at least one brush affixed to at least one of the first frame portion or the variably expandable portion. The first frame portion and the variably expandable portion together form a containment basin configure to confine a paving material deposited into the containment basin. The variably expandable portion is configured to laterally move relative to the first frame portion to change a width of the containment basin. The at least one brush is disposed inside of the containment basin and configured to spread the paving material on a paving surface.

An attachment apparatus for a distributor vehicle configured to apply asphalt onto a surface is provided. The attachment apparatus comprises a truss and a broom head attached to the truss. The broom head comprises a plurality of bristles. The attachment apparatus further comprises a drive assembly configured to shift the truss and the broom head between a raised position and a lowered position with respect to the surface.
