Abstract
ABSTRACT Traditionally evaluation of strength parameters of soil using plate load test is time-consuming, laborious and cumbersome process. This study is focused on evaluating the strength parameters of compacted soils, quickly and cost-effectively in terms of dynamic penetration index (DPI), dynamic resistance (DR), cone index (CI), and dynamic deformation modulus (E LWD ), analyzing their relationship with water content. Results, show strength parameters increases as water content decreases,with significant increase in DR, CI and E LWD for CBR changes from 5% to 10%, followed by marginal increase This study emphasized that the strength parameters vary with the physical properties of soils, for which correlations were proposed between CBR, DR, CI, and E LWD values, resulting in best-fit models. These parameters effectively indicate targeted in-situ strength conditions, aiding in assessing repeatability and uniformity of compaction. The mean DR, DPI, N, and E LWD were reported as 61.74 MPa, 6.41 mm/blow, 8 blows/100 mm, and 54.11 MPa, respectively from the field case study.
