ROTARY DRUM SOIL BLENDING FOR SOURCE ZONE REMEDIATION: VARIOUS APPLICATION SCENARIOS
Markesic, S., J. Rossabi, J. Haselow, J. Romano, and T. Adams.
Remediation Journal 28(3):57-66(2018)
The typical aim of soil blending is to homogenize the soil while effectively distributing amendments (e.g., oxidants, stabilizing or reducing agents, biological enhancements) to soil zones made accessible by blending. This homogenization, however, can increase the void ratio and disrupt the shear strength and bearing capacity of the soil; hence, an important component of the blending technology is proper recovery of these geotechnical parameters, which can be achieved by using well-known soil improvement techniques, such as amending all or a portion of the blended area with Portland cement or lime. This paper provides several case study examples of soil blending treatments of different contaminants and amendments in a variety of soil types.
