Estimation of soil compaction parameters based on Atterberg limits

In civil engineering works, soils are commonly used as construction materials. Compaction of soils is carried out to improve the strength of the soils. However, compaction tests are time-consuming and relatively expensive especially when many samples are to be tested. In this study, an alternative m...
