Abrégé

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.

Abrégé

A method for production of coated mineral grit for the manufacture of coating elements with a bituminous support, or with a support comprising a vinyl or acrylic adhesive, for roofing of buildings, the method includes: adding rough mineral grit to a mixer together with a first treatment mixture; mixing the rough mineral grit and the first treatment mixture until a coated mineral grit is obtained; heating the coated mineral grit to a predetermined firing temperature (Tc); and after heating the coated mineral grit, cooling the coated mineral grit to a predetermined intermediate cooling temperature (Tri). The first treatment mixture comprises: water; at least one pigment; at least one selected from the group consisting of sodium silicate and potassium silicate; kaolin; and at least one selected from the group consisting of an organo-siloxane and an organo-silane.
