| abstract |
A fabric, e.g., polypropylene fabric, is impregnated with a refined asphalt and an asphaltite such as Gilsonite, thus preparing a composite suitable for use as liner in a pond, as pavement surfacing, e.g., parking lot, driveway, play area surface, roofing or other covering or waterproofing material, or for molding to produce a molded body such as, e.g., construction blocks and structural forms. The asphaltite raises the ring and ball softening point of a straight asphalt system reducing cold flow and bettering weathering properties. The asphaltite can be used in cutbacks and emulsions and applied to one or more fabrics which can be the same or different and which can be variously arranged. |
