There is a method of plotting log e vs log p' . . . then the intersection of the two lines is the preconsolidation pressure - there is a paper that I have somewhere but you should be able to find on the net.

There was a really good book with a number of "case histories" that I had years ago - if I find time, I will try to find it. One thing that might be...
Getting back - - the project is divided into 4 packages - one is the dam, one is the powerhouse, one is the spillway/plunge pool and diversion tunnels and one is the actual turbines, et al. There will be 6 units at 600 MW each.
The Dam is an EPC contract and is carried out by a European...

The Rogun Dam will be at el. 1300 m when finished. Presently it is "known" as 335 m high but the actual foundation base was el 962 instead of the "design" el. 965 - so it could be called 338 m high. The Core will be where the RCC Pad...
G'day mates,
Just wondering if someone has the plasticity chart in excel already done so that I can add multiple data points on it.
Would appreciate if you do.
Cheers

ALso, I draw your attention to the fact that the nuclear gauge moisture content determination during the test is highly unreliable and on the high side. This was noted in Toronto years ago when the lab moisture was 70% of the nuclear gauge. Also USBR EM 1110-2-1911 and USBR DS13-10 both...
Thanks morecoffeeplz - working overseas for years, I was not familiar of the hydrometer replacement standard.
Don't drink the coffee although my sister is hooked. Ever try Luwak???

I have always understood that the clay size particles were those considered less than 0.002 mm. If one "googles" all the answers seem to confirm this. Yet, ASTM D422 indicates that clay size particles are less than 0.005 mm and colloidal particles are less than 0002 mm.
This is not addressed...
It seems to me that a thin "shotcrete layer" on the slope does not really "stabilize" the slope but acts in, as the OP stated, an erosion protection. It is not known as to the type of material onto which it was shot. For me, the slope needs to be stable on its own accord. That given, the...
Thanks mates . . . as emmgjld said, it was my understanding on oversize to rotate 3 times . . . agree that ASTM says only 180 degrees.
Appreciate your thoughts.
[cheers]
Question: Is the moisture content determined "at the time of the compaction" or is it determined, say 2 days later after it has been allowed to sit in hot sun?
I do not have access to ASTM D6938. Years ago, I remember that if one is using the troxler in a coarse soil (I am talking about 70% greater than #200 sieve, that one would take three readings with the nuclear guage but rotating the machine around the inserted rod by 120 deg - so that 3 readings...
We typically used 51 mm tubes for our projects in clays in Ontario. Question? - are you using "real" thin walled shelby tubes (meeting all the dimensional specifications as per ASTM D1587) or thin walled steel tubes?

Interestingly, Dr. Harr (Purdue) wrote a book on Particulate Medium . . . so you could,for the gravel use the stress distribution in that book - and then elastic in the clay . . . but for practical purposes, SRE's suggestion makes sense.
