An environmentally sound method for applying or fixing elements ( 2 ) to constructed objects used for road traffic. The element ( 2 ), which is at least partially made of a material that can be liquefied by mechanical energy, is positioned on the surface, is pressed against the surface, and is simultaneously subjected to a local mechanical stimulation to liquefy the liquefiable material, and the element ( 2 ) binds with the surface upon re-solidifying. A mobile device ( 1 ) for applying elements ( 2 ) of this type, includes device that can travel via rolls or rollers ( 4, 5 ) and that is provided with at least one oscillating unit ( 10 ) including a sonotrode ( 6 ), a converter ( 7 ) and of an amplifier ( 8 ), and with a generator ( 9 ). The element ( 2 ) may be a marking or signaling element to be applied to roads or tunnel walls.
