Abstract

This material discusses a methodology for non-destructive testing of soil density using ultrasonic measurement. The measurements were carried out with a material thickness gauge in which sound speeds of 1000 m/s, 1500 m/s and 2000 m/s were set during the test. The tested field is with black soil and shows good results at 2000 m/s, and it has been confirmed that humidity strongly affects the possibility of measurement. The obtained results compared with a vertical cone penetrometer show 99.99% dependence and the standard error is 1.24 kN.
