Traffic surface construction comprising at least one intermediate layer

Abstract

An economical, permanent construction of traffic surfaces that does not require an extensive use of resources and that is cost-effective to produce, and in particular that of protecting the parts of the bound and unbound layers of the traffic surface construction that lie beneath the surface layer of the carriageway from the ingress of water. A construction comprising at least one base layer, at least one asphalt surface layer and at least one intermediate layer applied to the at least one base layer, said at least one intermediate layer comprising a material that contains at least one silane-terminated polymer.

The invention claimed is: 
     
       1. A traffic surface construction comprising at least one asphalt upper layer and at least one intermediate layer, which is applied to at least one base layer, wherein the at least one intermediate layer has a material with at least one silane terminated polymer wherein the at least one silane terminated polymer is selected from the group consisting of: polyethylene oxide, polypropylene oxide, polyethylene oxide including urethane segments, polypropylene oxide including urethane segments, and/or and polyurethane. 
     
     
       2. The traffic surface construction according to  claim 1 , wherein the at least one silane terminated polymer is present in a quantity ranging from 20% by weight to 70% by weight, in relation to an entire quantity of material. 
     
     
       3. The traffic surface construction according to  claim 1 , wherein the at least one silane terminated polymer has terminal methoxy, ethoxy and/or propoxy groups. 
     
     
       4. The traffic surface construction according to  claim 1 , further including at least one poly methacrylic acid ester. 
     
     
       5. The traffic surface construction according to  claim 4 , wherein the ester group is formed from a remainder R having 2 to 20 carbon atoms. 
     
     
       6. The traffic surface construction according to  claim 4 , wherein the at least one poly methacrylic acid ester is present in a quantity ranging from 4% by weight to 15% by weight, in relation to an entire quantity of material. 
     
     
       7. The traffic surface construction according to  claim 1 , further including at least one filler and/or carbon black. 
     
     
       8. The traffic surface construction according to  claim 1 , further including a starter agent. 
     
     
       9. The traffic surface construction according to  claim 8 , wherein the starter agent includes polymers of acetate. 
     
     
       10. The traffic surface construction according to  claim 1 , wherein a thickness of the at least one intermediate layer is between 1 mm and 5 mm. 
     
     
       11. The traffic surface construction according to  claim 1 , including an aggregate and/or rubber granulate applied over the at least one intermediate layer. 
     
     
       12. The traffic surface construction according to  claim 11 , wherein the aggregate has a maximum grain size ≥1 mm. 
     
     
       13. The traffic surface construction according to  claim 1 , wherein the at least one base layer includes slabs having an edge length that is less than 2.5 m.
