Undisturbed and disturbed samples of cohesive soils were collected from eight different locations to investigate the possibility of estimating the Atterberg limits of cohesive soils from P-wave velocity measurements. Each soil type was classified according to the Unified Soil Classification System, and then Atterberg limits of soils were determined and P-wave velocity measurements carried out on the undisturbed samples of each soil type. P-wave velocity values were correlated with the corresponding values of Atterberg limits. It was found that liquid limit, plastic limit, and plasticity index exhibit good correlations with P-wave velocity. The relations follow a logarithmic function. Liquid limit, plastic limit, and plasticity index decrease with an increase in P-wave velocity. In addition, liquid limit, plastic limit, and plasticity index exhibit very good correlations with the ratio of P-wave velocity to water content. Liquid limit, plastic limit, and plasticity index decrease logarithmically with an increase in the ratio of P-wave velocity to water content. It can be concluded that the Atterberg limits of cohesive soils can be predicted from P-wave velocity measurements for preliminary investigations. The developed equations have some limitations and further study is required in this area.
