Abstract
Un produit de sous-couche comprend un tapis fibreux comportant une surface supérieure et une surface inférieure. Un revêtement dasphalte caoutchouté est appliqué sur la surface inférieure du tapis fibreux et sétend au moins partiellement dans le tapis. Dans une sous-couche lourde, un revêtement dasphalte oxydé est appliqué sur les surfaces supérieure et inférieure du tapis fibreux encapsulant généralement ce dernier, y compris le revêtement dasphalte caoutchouté fourni sur la surface inférieure du tapis. Les couches dasphalte oxydées peuvent être revêtues dune couche de libération comme du talc, des granules ou un polymère. Dans une sous-couche légère, une feuille de libération ou un revêtement divisé segmenté pour offrir une lisière pouvant être libérée et comprenant un polymère à traction élevée sur sa surface est appliqué sur lasphalte caoutchouté.
