Bituminous tile with grit coating and method for the production thereof

A method for producing a bituminous grit-coated tile, the method comprising, in order:

• (a) impregnating a support layer with a hydrocarbon solution comprising adhesion promoters, at a temperature in a range of from 120 to 180° C., the support layer comprising a base layer comprising non-woven glass fiber fabric, having a first major surface, to which a glass fiber net is coupled covering at least 80% of the first major surface, and a second major surface facing away from the first major surface;
• (b) covering the support layer, impregnated with the hydrocarbon solution comprising adhesion promoters, with a non-adhesive bituminous compound, at a temperature in a range of from 170 to 210° C., to define a first external bituminous layer covering the net and the first major surface, and a second external bituminous layer covering the second major surface;
• (c) depositing a grit comprising ceramic colored mineral granules on the second external bituminous layer, when the second external bituminous layer has a temperature in a range of from 120 to 170° C.;
• (d) cutting the support layer covered with the first and second external bituminous layers and with the grit to obtain from it a desired number of tiles.
