Bulk density values
Bulk density values
(OP)
Hello,
For a calculation, I need to know the bulk density values of some soils. Unfortunatly, it wasn't asked to the subcontractor who didt the surveys. So now, the only data I have are : the type of soil (SM-SP) ; particle size distribution, the specific gravity, the moisture content, the Atterberg limits and SPT test results (N).
Is there any kind of relationship between all those data and the bulk density of the soil, or else, do some typical values could be found for a soil type.
I would be thankfull to hear from you soon.

RE: Bulk density values
Then, if you assess the SPT values you should be able to get a 'feel' for the density of the material, i.e. N = 5 to 10 (loose), N = 10 to 30 (medium dense), N = 30 to 50 (Dense) and N > 50 (very dense).
It then comes down to assessing how dense the soil is, how much air voids will relate to this and what impact ths has on the final bulkd density. It will not be 100% accurate, but it should make it an estimate and not a guesstimate.
