Asphalt compaction device

Abstract

In one embodiment of the invention, a traditional roller, known in the industry, includes a front drum including an eccentric which provides a vibration which is transmitted to the surface to be compacted and a rear drum including another eccentric which provides another vibration which is also transmitted to the surface to be compacted. While this traditional roller is well known in the art, it may be modified to including a control box which synchronizes the movement of the eccentric of the front roller and the eccentric of the rear roller and a braking mechanism. While the braking mechanism is engaged, the synchronized vibrations of the front and rear roller allow the roller to continue compacting the warm asphalt without producing a pressure wave in front of the roller. The synchronization may also be controlled by the control box so that the vibrations created by the eccentrics may actually propel the roller forward.

1 . A vibrating compaction device, comprising: 
 a roller compactor including a front roller having a first eccentric and a rear roller having a second eccentric;    a braking mechanism adapted to lock the front roller; and    a synchronization unit adapted to synchronize a first vibration produced by the first eccentric and a second vibration produced by the second eccentric.    
   
   
       2 . The vibrating compaction device of  claim 1 , wherein the braking mechanism is further adapted to lock the rear roller.  
   
   
       3 . The vibrating compaction device of  claim 1 , wherein the synchronization unit is adapted to cause the first vibration and the second vibration to propel the vibrating compaction device in a forward direction.  
   
   
       4 . A vibrating compaction device, comprising: 
 a roller compactor including a front roller having an eccentric;    at least one pneumatic wheel; and    a braking mechanism adapted to lock the front roller, wherein the eccentric produces a vibration.    
   
   
       5 . The vibrating compaction device of  claim 4 , wherein the at least one pneumatic wheel propels the vibrating compaction device in a forward direction.  
   
   
       6 . The vibrating compaction device of  claim 4 , wherein the at least one pneumatic wheel guides the vibrating compaction device.  
   
   
       7 . A vibrating compaction device, comprising: 
 a roller compactor including a front roller having an eccentric; and    a braking mechanism adapted to lock the front roller, wherein the eccentric produces a vibration when said front roller is locked.
