Method for Producing a Road Surface, Preferably a concrete road surface, and road paver

Abstract

In the production of road surfaces of asphalt and concrete ( 33 ), it has been necessary hitherto to use different road pavers, which requires additional complexity, in particular when a wearing course ( 32 ) of concrete ( 33 ) is to be applied to a base ( 31 ) of asphalt. The invention provides to produce road surfaces of concrete ( 33 ) with a road paver intended for the processing of asphalt in that suspended vibrating bodies ( 23 ) are used which are inserted at least partially into the concrete ( 33 ) to be compacted. As a result, a road surface of concrete ( 33 ) can be produced with a road paver intended for the laying of road surfaces of asphalt. A laying screed ( 17 ) of the road paver is preferably guided rigidly, that is to say non-height-adjustably.

1 . A road paver having a drivable set of running gear ( 11 ) and at least one smoothing device which is arranged behind the running gear ( 11 ) as seen in the paving direction ( 12 ), and also compacting means for the road-building material in front of the smoothing device, wherein the compacting means are vibrating bodies ( 23 ) which are inserted at least partially into the road-building material. 
     
     
         2 . The road paver according to  claim 1 , wherein the vibrating bodies ( 23 ) are arranged between the running gear ( 11 ) and the smoothing device. 
     
     
         3 . The road paver according to  claim 1 , wherein the vibrating bodies ( 23 ) are arranged in a suspended manner between the running gear ( 11 ) and the smoothing device. 
     
     
         4 . The road paver according to  claim 1 , wherein the vibrating bodies ( 23 ) are arranged in at least one row extending transversely to the paving direction ( 12 ). 
     
     
         5 . The road paver according to  claim 1 , wherein the vibrating bodies ( 23 ) are suspended in a guided manner on a carrier ( 24 ). 
     
     
         6 . The road paver according to  claim 5 , wherein the vibrating bodies ( 23 ) are suspended in at least one row on the carrier ( 24 ). 
     
     
         7 . The road paver according to  claim 5 , wherein the vibrating bodies ( 23 ) are suspended in a height-adjustable manner on the carrier ( 24 ). 
     
     
         8 . The road paver according to  claim 1 , wherein the spacing of the vibrating bodies ( 23 ) from one another is adjustable. 
     
     
         9 . The road paver according to  claim 1 , wherein the vibrating bodies ( 23 ) are arranged in front of a transverse distribution device for the road-building material. 
     
     
         10 . The road paver according to  claim 1 , wherein the vibrating bodies ( 23 ) are arranged behind a transverse distribution device. 
     
     
         11 . The road paver according to  claim 1 , wherein the vibrating bodies ( 23 ) are designed to compact concrete ( 33 ). 
     
     
         12 . The road paver according to  claim 1 , wherein the vibrating bodies ( 23 ) each have their own vibrating drive. 
     
     
         13 . The road paver according to  claim 1 , wherein the vibrating bodies ( 23 ) are vibrating cylinders. 
     
     
         14 . A method for producing a road surface with a self-propelled road paver ( 10 ) from which road-building material is compacted with compacting means and then is smoothed by at least one smoothing device, comprising compacting the road-building material by vibration and in so doing inserting the compacting means at least partially into the road-building material. 
     
     
         15 . The method according to  claim 14 , further comprising driving the compacting means in an oscillating manner. 
     
     
         16 . The method according to  claim 14 , wherein the road-building material is concrete, and further comprising compacting the concrete ( 33 ) for a concrete road surface by the compacting means. 
     
     
         17 . The method according to  claim 14 , wherein the compacting means used are vibrating bodies ( 23 ). 
     
     
         18 . The method according to  claim 14 , further comprising guiding the smoothing device at the working height. 
     
     
         19 . The method according to  claim 14 , wherein the smoothing device is guided by a height controller.
