Use of petroleum-contaminated drilling wastes as sub-base material for road construction

摘要

In this study, petroleum-contaminated drilling wastes were stabilized by mixing pozzolanic fly ash, lime and cement with them so they could be used as sub-base materials for road construction. This stabilization produced physically,. Mechanically and chemically stabilized new mixtures. The Laboratory study consisted of unconfined compressive Strength, permeability, California bearing ratio, freeze/thaw (durability)and leachate on compacted stabilized samples, pH, electrical conductivity, cation exchange capacity and total metal contents on stabilized mixtures.
