    • A method of forming a roofing product can include providing a ceramic base material having an open structure. The method can also include filling the open structure of the ceramic base material with a bituminous material, wherein the bituminous material has no greater than approximately 5 weight % of abrasive particles. The method can further include applying a recycled roofing material adjacent to the ceramic base material after filling the open structure of the ceramic base material with the bituminous material. In a particular embodiment, an open structure of the ceramic base material is filled with a bituminous material that has no greater than approximately 2 weight % of abrasive particles or 0.1 weight % metal content. The recycled roofing material can be applied along one or both sides of the ceramic base material. The bituminous material may have a characteristic particle size that is smaller than a characteristic particle size of the recycled roofing material. In another embodiment, the roofing product having the recycled roofing material can have tear strength characteristics as compared to a different roofing product having a substantially the same construction but having abrasive particles embedded within the ceramic base material.
    • 形成屋顶产品的方法可以包括提供具有开放结构的陶瓷基材。 该方法还可以包括用沥青材料填充陶瓷基材的开放结构,其中沥青材料具有不大于约5重量%的磨料颗粒。 该方法还可以包括在用沥青材料填充陶瓷基材的开放结构之后,应用邻近陶瓷基材的再循环屋面材料。 在特定实施例中,陶瓷基材的开放结构填充有不大于约2重量%的磨料颗粒或0.1重量%金属含量的沥青材料。 再循环屋顶材料可以沿着陶瓷基材的一侧或两侧施加。 沥青材料可以具有小于再循环屋顶材料的特征粒径的特征粒径。 在另一个实施方案中,具有回收屋面材料的屋顶产品与具有基本上相同结构的不同屋顶产品相比可具有撕裂强度特性,但具有嵌入在陶瓷基材内的磨料颗粒。
