Soft Soil Settlement Remediation and Roadway Elevation Increase with Permeable Low-Density Cellular Concrete (PLDCC)

This paper will address the feasibility of using permeable low-density cellular concrete (PLDCC) in soft soil remediation and roadway elevation applications. In this discussion, the paper will examine the case study of a project conducted at West Lake Eloise Drive in Winter Haven, Florida, and will also review and evaluate data from recent studies conducted at the University of Missouri Kansas City related to the physical properties of PLDCC, including permeability, lightweight characteristics, compressive strength, and resistance to buoyancy. In its discussion of the West Lake Eloise Drive project, this paper will posit the effectiveness of 30-pcf (pounds per cubic foot) PLDCC in the remediation of settlement caused by soft soils as well as the proposed increase in elevation of roadways in areas that experience high water tables.
