Soil Backfilling monitoring
Soil Backfilling monitoring
(OP)
Hi guy,
For soil Proctor test, can the test result can be used in monitoring soil backfilling progress in certain area?(behind schedule) Or, can sieve analysis data plot against time can let tell us how far the backfilling progress is?
Thanks many

Thank you for replying my message. The job (Assignment) that I involve with was happened long time ago. I can’t hard recall. As I remember. What my team (QA/QC team) did was do the proctor test for the water content of the soil, and did the in-place density for 98% compaction. I remember I collected those data from the technician and put into a excel file. I then, remember the Highway department look into the data that I had gathered and they could tell how’s the backfill progress in the field. My supervisor had told me that as the bell shape curve generate from the proctor text result, and check against the standard bell shape curve they can tell the progress. I’m just wanted to know what is the science between it.
Thank you

RE: Soil Backfilling monitoring
As for monitoring, I suppose one might be concerned with a change in the predicted "shrinkage", which then may call for a change order to order more off site borrow, etc. than planned.
RE: Soil Backfilling monitoring
Thank you for you reply. Your brough out very intereting point if shrinkage occur on a particular area, and it require more change order to order more off site borrow to meet certain garde level.It will affect the construction progress, cause delay or fall behind?
