         12 . The slipform paver of  claim 11 , further comprising:
 at least one controller configured to automatically or manually control operation of the actuator.   
     
     
         13 . The slipform paver of  claim 12 , wherein:
 the controller is remotely controllable.   
     
     
         14 . The slipform paver of  claim 6 , wherein:
 the at least one movable sprayer assembly further includes at least one rotatable spraying line rotatable about a first axis of rotation, and the at least one spray nozzle is connected to the at least one rotatable spraying line and is arranged at an offset to the first axis of rotation such that a spraying direction from the at least one spray nozzle is aligned such that the at least one rotatable spraying line and the at least one spray nozzle rotate about the first axis of rotation as a result of spraying action of the at least one spray nozzle.   
     
     
         15 . The slipform paver of  claim 14 , wherein:
 the at least one spray nozzle includes at least two spray nozzles connected to the at least one rotatable spraying line on opposite sides in relation to the first axis of rotation, and the spraying directions from the at least two spray nozzles are arranged such that the at least two spray nozzles rotate about the first axis of rotation as a result of their spraying action.   
     
     
         16 . The slipform paver of  claim 1 , further comprising:
 at least one hose including a first hose end connected to the at least one movable sprayer assembly and movable with the at least one movable sprayer assembly.
