Abstract
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.
Claims8
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.
