The present disclosure sets out a method for processing bituminous road surfacing material from a road demolition. The bituminous road surfacing material is in the form of break out material and/or milled material. The following steps are carried out as part of the method: mixing the bituminous road surfacing material with water to form a mixture and adding a peroxide and/or a bicarbonate to the water and/or the mixture, in particular hydrogen peroxide and/or a bicarbonate.
A mastic asphalt finisher (1) for producing traffic surfaces on a substrate comprises at least one grit bunker (50) having a grit-discharging device; a first running gear arrangement having a first running gear unit (15) and a first running gear drive and also a second running gear arrangement having a second running gear unit (25) and a second running gear drive, which are arranged at opposite ends of the grit bunker (50) with respect to an x direction; wherein the first running gear arrangement comprises a first leg (11) which is connected to the grit bunker (50) so as to be pivotable via a first end about a first vertical leg axis and is connected to the first running gear unit (15) via a second end; and wherein the first running gear unit is movable relative to the grit bunker (50) in the vertical direction via a first lifting device, in particular a first levelling cylinder (12); and wherein the first running gear arrangement comprises a first pivoting device, in particular a first strut cylinder (13) which is arranged between the grit bunker (50) and the first leg (11) in such a way that the first leg can be pivoted relative to the grit bunker (50) by actuating the first pivoting device and in particular can be fixed statically, wherein the mastic asphalt finisher (1) comprises a levelling control device, whereby it is possible to control the first lifting device, in particular the first levelling cylinder (12), on the basis of a measurement variable on the first lifting device and/or on the first pivoting device, in particular on the first strut cylinder (13), in particular on the basis of a pressure in the first levelling cylinder (12) and/or of a pressure in the first strut cylinder (13), in order to compensate for deformations on the mastic asphalt finisher (1).

PREPARATION OF BITUMEN-CONTAINING ROAD SURFACE MATERIAL
The invention relates to a method for preparing bitumen-containing road surface material from road demolition, the bitumen-containing road surface material being present in the form of demolition material and/or milled material, and the method comprises the following steps: mixing the bitumen-containing road surface material with water to give a mixture; adding a peroxide and/or a bicarbonate to the water and/or to the mixture, in particular hydrogen peroxide and/or a bicarbonate.
The invention relates to a method for washing raw material, in particular excavated materials, crushed rock, and gravel, in a washing device (100), wherein the following steps are carried out: introducing the raw material into a wash water-containing trough (110) of the washing device (100), said wash water assuming a wash water level (140) in the trough (110) during the washing process; and discharging the washed raw material out of the trough (110). The washed raw material is discharged out of the wash water below the wash water level (140). The invention also relates to a device for washing raw material, comprising a trough (110) and a conveyor device arranged in the trough (110) for conveying the raw material. The trough (110) comprises an overflow drain (113) and a sluice (130) for discharging the washed raw material, said sluice (130) being arranged below the overflow drain (113).
