ABSTRACT:
A method and apparatus is disclosed for the removal of layers of concrete, particularly from roadways and motorways. This apparatus includes one or more nozzles located at one end of respective hollow shafts each of which is supported by an articulated joint which is mounted on a movable support. The nozzles are supplied with water by means of a high pressure pump upstream of which there is positioned a preliminary treatment system for treating the water itself. The nozzles are mounted on a movable slide or frame which is controlled by an electronic circuit operable to maintain them at a predetermined height with respect to the surface to be treated. Apparatus is also provided for the elimination of possible hindrances to the free downflow of the water jets against the surface to be treated.
