Thanks all. I’ve answered your questions below.
My response to the contractor was I would accept the failed test results. However, they are to continue moisture conditioning the sand, and must also continue to test the moisture content of the compacted lifts. I don’t want them placing totally...
BigH, I had the same thought. I don't know the answer but will be asking first thing Monday. I'm pretty sure it's same day testing, the moisture content is an oven dried sample (i.e. not taken from the nuke gauge).
Hi all, I have a project where the contractor struggles to meet the moisture content specification for a compacted sand fill. The specification is 95% of SMDD, -3% to +3% of OMC. The contractor easily meets the density ratio, but is often out of the OMC range on the dry side. I know that...
Thanks for the help everyone. Much appreciated!
Although I do still wonder if one should be very clear about saying the MAXIMUM deviator stress divided by 2, or the final deviator stress divided by 2 when the stress path reaches the critical state (I think this is what LRJ means by "deviator...
Hi all,
Can someone please enlighten me as to the correct way of calculating the undrained strength ratio (Su/σv0’) from the results of CU (compression) triaxial tests?
Not a single textbook or course notes I have seen actually describes how to do this, yet all the time in the literature you...
