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.

What is claimed is: 
     
         1 . A rubber tire roller for asphalt compaction, comprising:
 at least one rubber tire;   a spray device for spraying the rubber tire with a separation agent mixture composed of a first liquid and a second liquid,   wherein the roller comprises a first tank for the first liquid and a second tank for the second liquid, and in that the roller comprises a mixing device for mixing the first liquid provided by the first tank and the second liquid provided by the second tank for producing the separation agent mixture, that the roller comprises a first pump for conveying the first liquid from the first tank to the mixing device and/or a second pump for conveying the second liquid from the second tank to the mixing device, that the mixing device comprises a regulating device for adjusting a mixing ratio of the first liquid and the second liquid in the separation agent mixture with the regulating device comprising a control device that controls the first pump and/or second pump.   
     
     
         2 . The roller according to  claim 1 ,
 wherein the control device for controlling the regulating device is connected to a first actuating element and/or to a second actuating element for setting an operating mode of the spray device.   
     
     
         3 . The roller according to  claim 1 ,
 wherein the roller comprises a first supply line connecting the first tank with the mixing device for providing the first liquid and/or comprises a second supply line connecting the second tank with the mixing device for providing the second liquid.   
     
     
         4 . The roller according to  claim 1 ,
 wherein the first pump and/or the second pump is a hose pump, a gear pump or a diaphragm pump.   
     
     
         5 . The roller according to  claim 1 ,
 wherein the second tank and the roller are detachably connected to one another via a coupling device or in that the second tank comprises a drain for discharging the second liquid.   
     
     
         6 . The roller according to  claim 1 ,
 wherein the second tank is arranged within a covering of the roller or on an outer covering of the roller so as to be accessible from the outside.   
     
     
         7 . The roller according to  claim 1 ,
 wherein the mixing device comprises a water jet pump or a static mixer.   
     
     
         8 . The roller according to  claim 7 ,
 wherein the mixing device comprises a static mixer, and   wherein the static mixer is connected to a drain for discharging the separation agent mixture from the static mixer.   
     
     
         9 . The roller according to  claim 1 ,
 wherein the mixing device provides the separation agent mixture to a plurality of spray devices for different rubber tires.   
     
     
         10 . The roller according to  claim 1 ,
 wherein the roller comprises a measuring device for determining at least one of the following characteristics:
 viscosity of the second liquid, 
 temperature of the second liquid, 
 fill level of the first tank, of the second tank and/or of the static mixer, 
 temperature of the external environment, 
 temperature of one or more of the rubber tires or their surface, and/or 
 temperature of the asphalt to be compacted. 
   
     
     
         11 . A method for spraying a rubber tire of a roller for asphalt compaction with a separation agent mixture, comprising the following steps:
 providing a first liquid in a first tank and a second liquid in a second tank,   delivering the first liquid with a first pump and/or the second liquid with a second pump to a mixing device, wherein the mixing ratio of first liquid to second liquid in the mixed liquid is set via a control device of a regulating device, said control device controlling the first pump and the second pump,   mixing the first liquid and the second liquid in the mixing device in order to form a separation agent mixture during an operation of the roller, and   spraying the rubber tire with the separation agent mixture provided by the mixing device.   
     
     
         12 . The method according to  claim 11 ,
 wherein the regulating device and/or the spray device is actuated during the operation of the roller as a function of a viscosity or temperature of the second liquid and/or as a function of a temperature of at least one rubber tire of the roller or a surface of the at least one rubber tire and/or as a function of a temperature of the asphalt to be compacted and/or a temperature of the external environment.   
     
     
         13 . The method according to  claim 11 ,
 wherein the second liquid is drained from the second tank or the second tank is detached from the roller after operation of the roller has ended.   
     
     
         14 . The roller according to  claim 1 ,
 wherein the roller comprises a rubber tire roller.   
     
     
         15 . The roller according to  claim 2 ,
 wherein the first actuating element and/or the second actuating element is arranged in a driver's cabin of the roller.   
     
     
         16 . The roller according to  claim 10 ,
