  • the invention further relates to a method for producing a road surface, preferably a concrete road surface, according to the preamble of claim 11.
  • Road surfaces are made of asphalt or concrete.
  • road surfaces which consist partly of asphalt and concrete.
  • asphalt pavements the milled worn out asphalt pavement is replaced by a concrete pavement.
  • the invention has for its object to provide a method which makes it possible to produce a road paver for asphalt road surfaces and concrete road surfaces, especially concrete cover layers. It is another object of the invention to provide a paver for the production of asphalt road surfaces, which also concrete road surfaces can be produced.
  • a paver to solve this problem has the features of claim 1. Accordingly, it is provided to form the compression means as at least partially immersed in the road construction material Studttel Sciences.
  • the vibrating bodies make it possible to produce concrete pavements with a road paver intended for the production of asphalt pavings, in that, in contrast to the production of asphalt pavements, where pressure is exerted on the asphalt pavement material from above, the concrete is at least partially embedded therein submerged vibrating bodies is not compressed by pressure, but by vibrations.
  • the paver according to the invention fulfills an essential prerequisite that is required to produce concrete road surfaces.
  • a preferred development of the paver provides it to attach the vibrating body hanging preferably on a carrier. It may be a carrier on which the smoothing device and / or other components of the road paver are held.
  • the suspended arrangement allows the vibrating body to "dig in” by shaking movements to a designated depth into the fresh concrete for pavement preparation.
  • the suspended arrangement of the Rüttelores can be done on flaccid ropes or chains so that they can migrate laterally, so have no leadership in the production direction and transverse thereto.
  • it is provided to hang the RütteloresITE out, preferably on rigid or substantially rigid rods or tubes or similar strands. In this way it is prevented that the Garttel Congress realize do not dodge or move together due to the moving in the direction of production road paver.
