Abstract
Embodiments can include use of at least one additive to process or condition drill cuttings. The drill cuttings may be further used as a product, a component of a product, and/or in another process. For example, the drill cuttings may be used as aggregate for roadway material (e.g., asphalt stabilized material, asphalt cement concrete, etc.). The conditioning can include modifying a mechanical property of the roadway material, modifying the ability to encapsulate toxins within the asphalt so as to prevent or inhibit leaching of toxins, modifying the ability to absorb volatile hydrocarbon fractions to as to improve stability of the roadway material, etc.
Claims20
A conditioned material, comprising:
- an unconditioned material comprising one or more toxin and/or one or more volatile hydrocarbon fraction;
- a first additive configured to encapsulate the one or more toxin;
- and
- a second additive configured to absorb the one or more volatile hydrocarbon fraction.
Roadway material, comprising:
- aggregate comprising one or more toxin and/or one or more volatile hydrocarbon fraction;
- a first additive configured to encapsulate a predetermined amount of the one or more toxin;
- and
- a second additive configured to absorb a predetermined amount of the one or more volatile hydrocarbon fraction.
Roadway material, comprising:
- a first aggregate comprising one or more toxin and one or more volatile hydrocarbon fraction;
- a second aggregate comprising roadway material;
- a first additive configured to encapsulate a predetermined amount of the one or more toxin and to facilitate suspension of a predetermined amount of a globule of asphalt cement;
- and
- a second additive configured to reduce the amount of the first additive to achieve the predetermined level of stability for the roadway material.
A method of processing drill cuttings, comprising:
- adding an additive to the drill cuttings to at least one of:
- encapsulate a predetermined amount of one or more toxin that is part of the drill cuttings;
- and
- absorb a predetermined amount of one or more volatile hydrocarbon fraction that is part of the drill cuttings.
