Definitions

  • the invention relates to a method for removing old asphalt concrete from a road.
  • the aim of the invention is to overcome the abovementioned disadvantages and to this end superheated steam is blown on to the old asphalt concrete and the asphalt concrete softened in this way is pushed off and removed using a slide or shovel.
  • Softening of old asphalt concrete with the aid of infrared radiators or gas flames is unacceptable in connection with the emission of carcinogenic gases.
  • the use of superheated steam surprisingly leads to outstanding results. Softening can be achieved to an extent such that the asphalt concrete can be pushed off and removed without crushing of the stone fraction of the old asphalt concrete and without emission of hazardous gases, the particle size distribution of the stone fraction undergoing no change.
  • the superheated steam has a temperature of at least 105°C
  • the invention is outstandingly suitable for the removal of a layer of very open asphalt concrete lying on a layer of dense asphalt concrete, the very open asphalt concrete layer being softened by blowing superheated steam on to it and pushed off, while the dense layer of asphalt concrete, which is more difficult to heat, remains behind.
  • the --. to 5 cm thick top layer of very open asphalt concrete takes up the heat originating from the superheated steam much more rapidly than the layer of dense asphalt concrete below it.
  • the relatively expensive open top layer having a very specific particle size distribution can then also be processed separately to give new very open asphalt concrete. The invention thus makes it possible to remove the open top layer without damaging the dense underlayer.
  • An essential feature of the invention is that old asphalt layers can be removed rapidly and effectively without emission of hazardous gases and without stone dust being formed as a result of crushing and with retention of the original particle size distribution, by means of treating with superheated steam and pushing off mechanically using a slide or shovel.

Abstract

Afin d'enlever le béton bitumineux usé d'une chaussée en évitant de casser l'empierrement et en empêchant tout dégagement de gaz nocifs, on souffle de la vapeur surchauffée sur ledit béton bitumineux et on enlève ce dernier, ainsi ramolli, avec une pelle ou analogue.
