A layered floor pavement structure comprising: - a top layer that seals the layered structure; - a gel layer consisting of an elastic gel , the gel layer being located between a base material and the top layer; and - a barrier layer between the gel layer and the top layer; - wherein the elastic gel comprises: • a solid component , the solid component being polyurethane polymer matrix; • a liquid component , the liquid component being a plasticizer, the barrier layer being adapted to prevent the plasticizer from leaving the gel layer in the direction from the base layer to the top layer, the plasticizer being a chemical derivative of one or more vegetable oils, the plasticizer being a polyester comprising at least four fatty acids, the polyester being a transesterification reaction product of a transformation of the one or more vegetable oils into the polyester, wherein in the transesterification reaction the glycerol of triglyceride molecules is replaced by another alcohol backbone or by a polyoxymethylene (POM) resin molecule, the other alcohol backbone or the POM resin having a carbon atom chain that is longer than the carbon atom backbone chain of glycerol, the liquid component being comprised in cells of the polyurethane polymer matrix. - a top layer that seals the layered structure; - a gel layer consisting of an elastic gel , the gel layer being located between a base material and the top layer; and - a barrier layer between the gel layer and the top layer; - wherein the elastic gel comprises: • a solid component , the solid component being polyurethane polymer matrix; • a liquid component , the liquid component being a plasticizer, the barrier layer being adapted to prevent the plasticizer from leaving the gel layer in the direction from the base layer to the top layer, the plasticizer being a chemical derivative of one or more vegetable oils, the plasticizer being a polyester comprising at least four fatty acids, the polyester being a transesterification reaction product of a transformation of the one or more vegetable oils into the polyester, wherein in the transesterification reaction the glycerol of triglyceride molecules is replaced by another alcohol backbone or by a polyoxymethylene (POM) resin molecule, the other alcohol backbone or the POM resin having a carbon atom chain that is longer than the carbon atom backbone chain of glycerol, the liquid component being comprised in cells of the polyurethane polymer matrix. • a solid component , the solid component being polyurethane polymer matrix; • a liquid component , the liquid component being a plasticizer, the barrier layer being adapted to prevent the plasticizer from leaving the gel layer in the direction from the base layer to the top layer, the plasticizer being a chemical derivative of one or more vegetable oils, the plasticizer being a polyester comprising at least four fatty acids, the polyester being a transesterification reaction product of a transformation of the one or more vegetable oils into the polyester, wherein in the transesterification reaction the glycerol of triglyceride molecules is replaced by another alcohol backbone or by a polyoxymethylene (POM) resin molecule, the other alcohol backbone or the POM resin having a carbon atom chain that is longer than the carbon atom backbone chain of glycerol, the liquid component being comprised in cells of the polyurethane polymer matrix. <EOS>
