Abstract

A bituminous tile with grit coating may include: a support layer including a base layer made of non-woven glass fiber fabric, having a first major surface to which a glass fiber net is coupled which covers at least 80% of the first major surface; a first external bituminous layer covering the net and the first major surface; a second external bituminous layer covering a second major surface of the base layer, facing away from the first major surface; a grit including ceramized colored mineral granules, covering the second external bituminous layer. A method for producing such a bituminous tile may include: (a) impregnating the support layer at 120-180° C.; (b) covering the impregnated support layer with non-adhesive bituminous compound at 170-210° C. to define the first and second external bituminous layers; (c) depositing the grit on the second external bituminous layer at 120-170° C.; (d) cutting the covered support layer to obtain tiles.
