Volume of uncompacted soil material
Volume of uncompacted soil material
(OP)
Hi,
i would like help to solve this issue.
I have 78000 m^3 compacted soil (gravel and sand)from river deposit (embankent construction). Max Density 2,2 t/m^3
and loose density 1,67 t/m^3. I would like to find the uncompacted material that we excavate from borrow pit.
Thanks

RE: Volume of uncompacted soil material
You have a project where the earth fill will be placed in an engineered embankment. Let's say the target specification is 95 to 100 percent compaction, so we'll use 97.5%. That would equate to 2.15 t/m3 for the engineered density. For these conditions, for every 1 m3 that you excavate you'd get 0.93 m3 in the embankment.
Who cares about the density in the truck? Just how is that a relavent concept (i.e., maybe I'm missing something)?

If that's the case, the swell factor is what needs to be calculated.

and thank all for replies
I want to pay one subcontractor who constructed a embankment. The volume of embankment is 78000m3 but i must pay to him the material that he excaveted. Material is sand-gravel with MD(proctor) 2,2 t/m3 and loose density 1,67t/m3. So how much he excavate. He wants 78000*1,3 but i think is too big this value. Thanks

RE: Volume of uncompacted soil material
Find the in situ density of the material (sand cone, nuke, drive cylinder, etc.), and then divide THAT number by 1.67 TCM to find the bulking factor. But check your contract first to figure out what you are actually paying for.
RE: Volume of uncompacted soil material
Previous replys are correct - it does depend on how the contract is written. The excavated material could be defined with the bulk density included. If this is case, I agree with everything Erdbau stated on how to calculate.
