Abstract
Cuttings from drilling through or into natural rock and/or soil can be incorporated into useful, high quality load-bearing structures such as vehicle roads and pads for deep drilling rigs. This process recycles a material previously regarded as valueless at best and often as a pollution hazard. The cuttings, optionally mixed with drilling mud and/or soil, are converted to the useful structures by pozzolanic and/or cementitious reactions after being mixed with suitable other materials and/or are bonded into the useful structures by asphaltic materials.
