Method of forming a multi-course paver for paving multi-course road surfaces, and multi-course paver

Abstract

A method to form a multi-course paver from two independent pavers, namely a lower base paver ( 10 ) and an upper paver ( 11 ) saddled thereon using the piggyback principle. Both the base paver ( 10 ) and the upper paver ( 11 ) can be used as stand-alone pavers for producing single-layer road surfaces. Therefore, the invention does not require any costly add-on devices, which can be used only for multi-course paving, for paving the second course of the road surface.

       10 . Method according to  claim 8 , wherein at least a paving screed ( 19 ), which is removed from the upper paver ( 11 ), is suspended on the carrier device. 
   
   
       11 . Method according to  claim 1 , wherein a base course or binder course is paved by the base paver ( 10 ) and a wearing course is paved by the upper paver ( 11 ). 
   
   
       12 . Multi-course paver for paving a multi-course road surface, comprising a base paver ( 10 ) and a device for producing a second course of the road surface, wherein an upper paver ( 11 ) is arranged above the base paver ( 10 ) to form the device for producing the second course of the road surface.
