Method of forming a roofing product including a ceramic base material and recycled roofing material
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.
1. A method of forming a roofing product comprising:
providing a ceramic base material having an open structure;
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; and
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.
2. The method of claim 1 , wherein filling the open structure of the ceramic base material comprises saturating the ceramic base material with the bituminous material to substantially fill the open structure of the ceramic base material.
3. The method of claim 1 , further comprising heating the bituminous material such that it is in a softened state, and wherein filling the open structure of the ceramic base material comprises submerging ceramic base material into the softened bituminous material.
4. The method of claim 3 , wherein heating the bituminous material comprises heating a mixture of asphalt and filler.
5. The method of claim 4 , wherein the bituminous material comprises filler particles having a hardness that is less than a hardness of the ceramic base material.
6. The method of claim 1 , wherein after filling the open structure, the bituminous material occupies a volume no greater than a perimeter volume of the ceramic base material.
7. The method of claim 1 , wherein after filling the open structure, the bituminous material occupies a volume greater than a perimeter volume of the ceramic base material.
8. The method of claim 1 , further comprising forming the recycled roofing material.
9. The method of claim 8 , wherein forming the recycled roofing material comprises heating a mixture of asphalt and recycled roofing articles.
10. The method of claim 1 , wherein the recycled roofing articles comprise post-consumer roofing articles.
11. The method of claim 1 , wherein the recycled roofing articles comprise pre-consumer roofing articles.
12. The method of claim 1 , wherein the recycled roofing articles comprise post-industrial roofing articles.
13. The method of claim 1 , wherein the recycled roofing articles make up at least approximately 5 weight % of the recycled roofing material.
14. The method of claim 1 , wherein the recycled roofing articles make up at least approximately 10 weight % of the recycled roofing material.
15. The method of claim 1 , wherein the recycled roofing articles make up at least approximately 20 weight % of the recycled roofing material.
16. The method of claim 1 , wherein the recycled roofing material has a softening point no greater than 125° C.
17. The method of claim 1 , wherein applying a recycled roofing material is performed such that the recycled roofing material is adjacent to one of principal sides of the ceramic base material.
18. The method of claim 1 , wherein applying the recycled roofing material is performed such that the recycled roofing material is adjacent to opposite principal sides of the ceramic base material.
19. The method of claim 1 , further comprising applying roofing granules to an exposed surface of the roofing product after applying the recycled roofing material.
20. The method of claim 1 , further comprising applying a release sheet to an exposed surface of the roofing product after applying the recycled roofing material.
21. The method of claim 1 , wherein a characteristic particle size of the recycled roofing material is smaller than a characteristic particle size of the bituminous material.
