Abstract

The present study aims to obtain a relationship between the ultrasonic pulse velocity which is one of nondestructive method of material testing and some of soil mechanical and physical properties. In this study a relationship between the ultrasonic pulse velocity through the soil samples and the unconfined compressive strength, dry density and curing time was obtained in high plasticity clayey soil. The soil was compacted in the cases of natural condition in standard and modified compaction effort, and in the treated condition with ( 2,4,6,8 ) percent of lime, compacted with modified compaction effort for three percent of water content(O.M.C, O.M.C ±4) these samples cured in (25°)temperature in different curing time ( 0,2,10,20,42 ) day . After curing time end, all samples tested in ultrasonic device and unconfined compressive strength device. The results obtain from these tests, analyze and get a good relationship between the ultrasonic pulse velocity and the unconfined compressive strength, dry density and curing time with high correlation coefficient in all properties
