Abstract
The present invention provides a novel method to produce grade road base material using recycled oilfield waste, called “oil and gas waste,” more specifically, drilling waste and aggregate and a novel road base material. Hydration and mixing of the waste materials along with a binder, will achieve an irreversible pozzolanic chemical reaction necessary for stabilization into a road base. An asphalt emulsifier may be included in the binder to manufacture asphalt stabilized road base. The entire method is a cold batch process.
Claims10
A method of processing waste material comprising the following steps:
- obtaining drilling waste material from a first offsite location;
- obtaining aggregate from a second location;
- transporting the drilling waste and aggregate to a treatment site;
- and
- processing transported material, on an impervious man-made layer, said processing including at least the steps of:
- passing the drilling waste and the aggregate through a screen, batch mixing the aggregate, the drilling waste and cement or fly ash to form an environmentally safe, structurally sound road base material.
A method of processing waste material comprising the following steps:
- obtaining drilling waste material from a first offsite location;
- obtaining aggregate from a second location;
- transporting the drilling waste and aggregate to a treatment site;
- and
- processing transported material, on an impervious man-made layer, said processing including at least the steps of:
- placing the drilling waste and the aggregate in a separator, batch mixing the aggregate, the drilling waste and cement or fly ash to form an environmentally safe, structurally sound road base material, the separator placed above the mixer of the mixing step so that the material passing through the separator will enter the mixer of the mixing step.
