Prediction of CBR Using Dynamic Cone Penetrometer

Jan 01, 1997Introduction. The dynamic cone penetrometer (DCP), since being introduced by Scala in 1956, has been successfully ultilized for estimating the strength of soils.The DCP was studied mainly in relation to application in pavement structures and was primarily correlated with California Bearing Ratio (CBR),, .Since in situ CBR testing is expensive, relatively slow to conduct, and generally not

A CBR value of 2% is usually found for clay, high-quality sub-base will have CBR values between 80% and 100%, and some sands may have values around 10%. The CBR testing can be applied to soils with a maximum particle size of 20 mm. For soils with bigger particles, other types of bearing capacity can be used like the Plate Bearing Test.

Jul 31, 2021Concrete strength also comes into play, but most slab concrete is around 3000 to 4000 psi, so it's not a major factor. The tensile strength of concrete is typically taken as 10 to 15% of the compressive strength, so only about 400 or 500 psi. Compare that to the tensile strength of Grade 60 rebar, which is 60,000 psi.
