WebResults indicate that the tapered joint type has better strength in terms of the Dynamic Cone Penetrometer and Falling Weight Deflectometer analyses, less longitudinal … WebOn the other hand, the Dynamic Cone Penetrometer (DCP) is a device used to evaluate in-situ resistance of unaltered or compacted materials soils [3]. DCP was developed in South Africa in the 1960s by Dr. D. J. Van Vuuren to simply estimate in-situ support capacity of subgrade materials and layers making up pavement [4], [5].

The penetration depth is recorded after every 5 blows. A number... WebThe cone factor which is the most important for reliable estimation of undrained shear strengthfrom cone penetration was evaluated considering the plasticity index of the soil. The result showed that the cone factor ranges from 11.26 at plasticity index of 12.7 to 16.19 at plasticity index of 30. The result showed an increasing trend.
