<p>The method for the production of cover layer or supporting layer for roads, paths and other traffic areas, comprises producing a mixture containing mineral materials, and a polymer reaction mixture and/or if necessary further additives, then applying and hardening on a base material. The mineral material consists of charged mineral material having heavy metals. The polyurethane reaction mixture is available through mixing of isocyanates with components of two hydrogen atoms reactive against isocyanate, and/or if necessary chain extenders and/or crosslinking agents and catalysts. The method for the production of cover layer or supporting layer for roads, paths and other traffic areas, comprises producing a mixture containing mineral materials, and a polymer reaction mixture and/or if necessary further additives, then applying and hardening on a base material. The mineral material consists of charged mineral material having heavy metals. The polyurethane reaction mixture is available through mixing of isocyanates with components of two hydrogen atoms reactive against isocyanate, and/or if necessary chain extenders and/or crosslinking agents, catalysts and other additional materials. The isocyanate is aromatic isocyanate. The component with two hydrogen atoms consists of hydroxyfunctional component with hydrophobic group, which has hydroxyfunctional oleochemical component, and an aromatic hydrocarbon resin modified with phenol. An independent claim is included for a cover layer or supporting layer for roads, paths and other traffic areas.</p> |
