Road construction, apparatus and method for realizing such a road construction

Abstract

The invention relates to a road construction and to a method for realizing such a road construction comprising a foundation layer, a road surface provided on top of the foundation layer, and a binder course provided between the foundation layer and the road surface for bonding the road surface to the foundation layer. In the binder course metal particles are incorporated. The metal particles form threads and are iron particles. The binder course comprises bitumen that is incorporated in a fleece.

What is claimed is:  
     
         1 . A method for realizing a road construction, wherein on a foundation layer a binder course is applied, in which particles are incorporated that are sensitive to excitation by electromagnetic waves, in that on the binder course a road surface is applied, and in that the bonding of the road surface on the foundation layer is realized by electromagnetically heating the binder course.  
     
     
         2 . A method according to  claim 1 , wherein the binder course with the incorporated particles is applied on the foundation layer by unwinding it from a roll of a prefabricated bituminized fleece.  
     
     
         3 . A method according to  claim 1 , wherein the binder course is applied by spraying bitumen followed by scattering the particles over the bitumen.  
     
     
         4 . A method for the removal of a road surface applied on a foundation layer, wherein a binder course is present between the road surface and the foundation layer, wherein the binder course comprises particles that are sensitive to excitation by electromagnetic waves, and in that the binder course is subjected to electromagnetic heating to soften the binder course prior to its removal.  
     
     
         5 . A fleece, wherein the same is bituminized and incorporates particles that are sensitive to excitation by electromagnetic waves.  
     
     
         6 . A fleece according to  claim 5 , wherein the same is wound onto a roll and can be unrolled.  
     
     
         7 . A road construction comprising a foundation layer, a road surface provided on top of the foundation layer, and a binder course provided between the foundation layer and the road surface for bonding the road surface to the foundation layer, wherein the binder course incorporates particles that are sensitive to excitation by electromagnetic waves.  
     
     
         8  A road construction according to  claim 7 , wherein the binder course comprises bitumen that is incorporated in a fleece.  
     
     
         9 . A road construction according to  claim 7 , wherein the road surface comprises a sound-absorbing asphalt mattress or rubber mat.  
     
     
         10 . A road construction according to  claim 9 , wherein the asphalt mattress or rubber mat is covered with a perforated top layer.  
     
     
         11 . A road construction according to  claim 9 , wherein the top layer is selected from a layer of bioresin comprising carborundum and a bituminized fleece enriched with chippings.  
     
     
         12 . An apparatus suitable for use in a method for realizing a road construction, comprising a foundation layer, a road surface on top of the foundation layer, and a binder course applied between the foundation layer and the road surface for bonding the road surface to the foundation layer, wherein the same comprises electromagnetic heating means for the thermal activation or deactivation of the binder course.  
     
     
         13 . An apparatus according to  claim 12 , wherein the same is mobile to facilitate the successive processing of adjacent road sections.  
     
     
         14 . An apparatus according to  claim 12 , wherein the same has wheels and in that the heating means are provided between the wheels, mounted on a frame that is carried by the wheels, while the heights of the frame can be adjusted in relation to the wheels.
