Abstract: Relative coarse flakes fabricated from used and manufacturing scrap asphalt shingle material are finish processed into ground cover and/or erosion control products. Processing of the flakes include (i) softening the surface of the flakes, (ii) embedding a surface treatment material into the softened surface of the flakes, and either (iii) supplying the flake as loose ground cover, or (iv) compressing the flakes into a portable mat.

Abstract: Used and manufacturing scrap asphalt shingle material is processed into a relatively coarse material comprising pieces or flakes of a maximum predetermined size. The flakes are finish processed into a composite board product in a method that includes (i) mixing the flakes with a relatively high percentage content of solvent suffused fiber, (ii) grinding and heating the flakes and fiber to form a homogenous semi-liquid mixture, (iii) extruding and conveying the homogenous mixture to a board forming station, and (iv) compressing the mixture into the composite board product.
