The present invention relates to a method for producing cover layers for roads, streets, and other traffic surfaces, wherein a mixture, containing mineral material and a polyurethane reaction mixture, and optionally further additives, is produced, applied to an underlying surface material, compacted using a contact pressure of at least 5 N/cm2, and cured, the work being per-formed substantially without the use of solvents. Furthermore, the present invention relates to cover layers for roads, streets, and other traffic surfaces, obtainable according to such a method.
La présente invention concerne un procédé de fabrication de couches de couverture contenant des matières minérales pour des routes, des chemins, et autres surfaces de circulation, consistant à fabriquer un mélange contenant du matériau minéral et un mélange réactionnel de polyuréthane, ainsi que le cas échéant d'autre additifs, à l'appliquer sur un matériau substrat, à le tasser et le faire durcir avec une pression d'au moins 5 N/cm2, ce travail se faisant sensiblement sans recours aux solvants. L'invention concerne également des couches de couverture pour des routes, des chemins et autres surfaces de circulation s'obtenant avec un tel procédé.
