The paper describes the use of the nondestructive and penetration tests such as the Soil Stiffness Gauge (SSG), the Dynamic Cone Penetrometer (DCP), and the Time Domain Reflectometry (TDR) for evaluating the compaction characteristics of foundation soils. A comprehensive laboratory experimental program was conducted for the SP, SW-SM, SM, CL soil specimens. The SSG, DCP, TDR, plate load test (PLT), California Bearing Ratio (CBR) test, and the sand cone test were performed for compacted soil

The interpreted results show that the nondestructive and penetration tests can quickly and quantitatively evaluate the compaction characteristics of soils with similar performance. The TDR can measure the water content of soils with high accuracy when testing soils with a water content of less than 15%. The results show that the SSG modulus is approximately two times higher than the PLT modulus. The SSG and DCP measurements have a log-log correlation between the soil stiffness and the shear strength of soils.
