摘要： The present invention relates to a method of manufacturing terra cotta pavings which may be used for ground surfacing, said pavings not being frost-susceptible, being porous and water-permeable, comprising the steps of: intimately mixing 100 parts by volume of clay with 80 to 160 parts by volume of dry, non-compressed sawdust, essentially formed of particles whose average diameter is included between 0.5 mm and 4 mm; adding water such that the total water content is between 8 and 30% by weight with respect to the weight of the mixture; shaping the pavings under pressure; drying the pavings; baking the pavings at a temperature between the temperature, above which the terra cotta is not frost-susceptible, and the melting temperature of this clay, and subjecting the faces of the pavings to pumicing.
