A Review : Experimental Study on Compacted Soil Using Ultrasonic Pulse Velocity Test

Abstract

Soil testing is very important to determine the load bearing capacity and strength of the soil. While soil testing we calculate the index properties such as water content, specific gravity, bulk density, dry density, consistency limit etc. And other geotechnical properties like compressive strength and shear strength. The specimens were prepared for the laboratory test by using proctor compaction method. The proctor mould of (100 mm dia.) and (125 mm length) is used. By using direct transmission method the wave velocity of each compacted specimen is measured. In this study the tests were conducted for investigating the use of Ultrasonic Pulse Velocity (UPV) over 16 samples of compacted clayey soil from Wanadongri region. Determining the index properties using the old methods and comparing it with the UPV results. Finally the calibration curve is plotted using the observations such as water content vs. velocity, dry density vs. velocity, bulk density vs. velocity, compressive strength vs. velocity. The curve shows that which of them is more efficient.
