I have four samples from the same site but different depths at equal intervals(0.5,1.0,1.5 and 2.0meters), I have conducted some geotechnical properties test on them but I now have very few samples for (1.0,1.5,2.0) but for 0.5m I have enough such that I have performed all the needed tests now I want to estimate the ones I couldn't perform due to insufficient samples. For 1.0,1.5 and 2.0 I have obtained their particle size distributions, liquid limits, plastic limits, shrinkage limits, natural moisture contents, specific gravities, volumetric swell. I want to know if there is any professional way of estimating/predicting the OMC,MDD,CBR value, Compression index, coefficient of consolidation and the coefficient of permeability?
Hi.
Yes you can use statistical regression equations to estimate compaction parameters and other geo technical engineering properties based on basic soil index properties. I recommend references by Dr. Das. For example:
Fundamentals of geo technical engineering. Or essential of geotechnical engineering. They contain some of these expressions.

Dear Colleague
Approximate values for some of the required soil properties, like soil compressibility, can be estimated using numerous empirical correlation equations to obtain preliminary evaluations. It is important to know the reliability of these equations before using them. The group of equations that proposed to all soils are recommended. Some of these equations are attached.
