Asphalt-based patch composition and method
An asphalt cold-patch compound composition and method are disclosed. The compound can include bituminous material and an oil binder mixed according to a ratio. For example, recycled roofing shingles and used motor oil can be mixed according to a ratio of about 9:1 to about 20:1. The compound is suitable for patching surfaces, such as roads, and can be placed in service without heating. The asphalt cold-patch compound can be made from recycled materials and can be applied without specialized heating equipment.
1. A compound for cold-patch applications, the compound consisting of:
a bituminous material, wherein the bituminous material consists of recycled asphalt roofing shingles ground into a ground particulate bituminous material and up to 1.5% of material selected from the group consisting of fiberglass, felt, film, shingle backer material, and combinations thereof, wherein one hundred percent of the bituminous material passes through a 0.25 inch screen; and
a binder consisting of oil or oil containing metal particles,
wherein a weight ratio of the ground particulate bituminous material to the binder is between about 9:1 to about 20:1,
wherein the compound is a loose composition of ground particulate bituminous material coated with oil after packaging, during transportation, and during application, and
wherein the compound forms a single piece following application of the compound to a surface.
2. The compound for cold-patch applications according to claim 1 , wherein each of the particles of the ground particulate bituminous material have a cross-sectional dimension of about 0.187 inch or less.
3. The compound for cold-patch applications according to claim 1 , wherein, at least 85% of the ground particulate bituminous material has a cross-sectional dimension of about 0.187 inch or less.
4. The compound for cold-patch applications according to claim 1 , wherein the oil binder consists of used motor oil.
5. A compound for cold-patch applications, the compound consisting of:
