Claims24
A composition comprising
- treated drill cuttings having a particle size distribution and plasticity characterization of a silty sand (SM), determined according to the Unified Soil Classification System (USCS), wherein the treated drill cuttings comprise from about 30 to about 70 wt % plagioclase;
- and
- a moisture content sufficient to form a California Bearing Ratio (CBR) of at least about 60, determined according to ASTM D 1883 or ASTM D 4429.
A method, comprising:
- providing an amount of treated drill cuttings having a particle size distribution and plasticity characterization of a silty sand (SM), determined according to the Unified Soil Classification System (USCS);
- blending the treated drill cuttings with less than about 30 wt % of a granular additive;
- and
- adding an amount of water to the treated drill cuttings sufficient to form a composition having a California Bearing Ratio (CBR) of at least about 60, determined according to ASTM D 1883 or ASTM D 4429;
