Abstract
A system for producing an asphalt mix output suitable for use as an asphalt pavement is provided. The system may include a preliminary mixing unit configured to mix asphalt shingles with hot fluid asphalt to melt the asphalt shingles. The molten asphalt formed from the asphalt shingles and the hot fluid asphalt may be mixed with aggregate material and/or recycled asphalt material to form an asphalt mix output. An intermediate tank may store the molten asphalt prior to mixing with the aggregate material and/or the recycled asphalt material
Claims20
A method for producing asphalt mix, comprising:
- mixing and heating a fluid asphalt input and an asphalt shingle input in a preliminary mixing unit to melt the asphalt shingle input and produce a molten asphalt;
- directing the molten asphalt and a particulate input into a primary mixing unit;
- and
- mixing the molten asphalt with the particulate input to produce an asphalt mix output.
A preliminary mixing unit for asphalt, comprising:
- a tank;
- a first inlet port connected to the tank and configured to receive an asphalt shingle input;
- a second inlet port connected to the tank and configured to receive a fluid asphalt input;
- a heater configured to heat the asphalt shingle input and the fluid asphalt input in the tank;
- a mixer configured to mix the asphalt shingle input and the fluid asphalt input in the tank and melt the asphalt shingle input to produce a molten asphalt;
- and
- an outlet port configured to output the molten asphalt.
