Abstract

Organic soils generally are characterized by low strength and high compressibility. Visual observations of State Road 15/US 98 in western Palm Beach County, Florida indicate numerous cracking and significant rutting and raveling along the roadway caused by the consolidation and long-term secondary compression of the organic soils due to soil and pavement dead load. Since sampling of undisturbed soft organic soils is difficult, and subsequent laboratory tests are expensive and time-consuming, there is a need for rapid in-situ characterization of these unstable foundation soils. This study evaluates the capabilities of Piezocone Penetration tests (CPTu), coupled with pore pressure dissipation tests, for estimating the strength, modulus, compressibility, and time rate of consolidation characteristics of organic soils and peat in Florida. The compression index (Cc) and coefficient of consolidation (cv), predicted from CPTu, showed reasonable correlation with laboratory-derived properties.
