Method for paving a multi-layer road surface

Abstract

To pave a multi-layer road surface, a first pavement layer is paved along a roadway using a first road paver. A second pavement layer is paved over the first pavement layer using the first road paver or using a second road paver. Upon paving the first pavement layer, paving data is recorded that allows determining at least a progression track traveled during paving of the first pavement layer by a screed outer edge of the first road paver. The paving data is used to control the first road paver or the second road paver when the second pavement layer is paved.

What is claimed is:

         2 . The method according to  claim 1 , wherein the first road paver or the second road paver is controlled at least in part in an automated manner based on the paving data when the second pavement layer is paved. 
     
     
         3 . The method according to  claim 1 , wherein the screed outer edge is a left screed outer edge of the first road paver, and wherein the paving data further allows determining a progression track traveled during paving of the first pavement layer by a right screed outer edge of the first road paver. 
     
     
         4 . The method according to  claim 1 , wherein the paving data allows determining a progression track traveled during paving of the first pavement layer by a reference point that is stationary relative to a chassis of the first road paver. 
     
     
         5 . The method according to  claim 4 , wherein the reference point comprises a theoretical turning point of the first road paver. 
     
     
         6 . The method according to  claim 1 , wherein the paving data allows determining a progression through which an orientation of the first road paver went during paving of the first pavement layer. 
     
     
         7 . The method according to  claim 1 , wherein the paving data allows determining a progression through which a lateral inclination angle of a screed of the first road paver went during paving of the first pavement layer. 
     
     
         8 . The method according to  claim 1 , wherein recording the paving data comprises determining positions of at least two position measuring points in a stationary coordinate system, wherein the two position measuring points are provided in a stationary manner at a chassis of the first road paver. 
     
     
         9 . The method according to  claim 1 , wherein steering of the first road paver or the second road paver is controlled based on the paving data when the second pavement layer is paved. 
     
     
         10 . The method according to  claim 1 , wherein steering of the first road paver or the second road paver is controlled in an automated manner based on the paving data when the second pavement layer is paved. 
     
     
         11 . The method according to  claim 1 , wherein a screed width setting of the first road paver or the second road paver is controlled based on the paving data when the second pavement layer is paved. 
     
     
         12 . The method according to  claim 1 , wherein a screed width setting of the first road paver or the second road paver is controlled in an automated manner based on the paving data when the second pavement layer is paved. 
     
     
         13 . The method according to  claim 1 , wherein a lateral inclination setting of a screed of the first road paver or the second road paver is controlled based on the paving data when the second pavement layer is paved. 
     
     
         14 . The method according to  claim 1 , wherein a lateral inclination setting of a screed of the first road paver or the second road paver is controlled in an automated manner based on the paving data when the second pavement layer is paved. 
     
     
         15 . The method according to  claim 1 , wherein the progression track traveled by the screed outer edge of the first road paver during paving of the first pavement layer is determined from the recorded paving data and is used, with or without prior processing, as a target track for the screed outer edge of the first road paver or a screed outer edge of the second road paver when the second pavement layer is paved. 
     
     
         16 . The method according to  claim 15 , wherein the progression track is used with the prior processing, and the prior processing comprises smoothing and/or offsetting the progression track. 
     
     
         17 . The method according to  claim 1 , wherein a progression track traveled by a reference point that is stationary relative to a chassis of the first road paver during paving of the first pavement layer is determined from the recorded paving data and is used, with or without prior processing, as a target track for the reference point of the first road paver or a reference point that is stationary relative to a chassis of the second road paver when the second pavement layer is paved.
