CWALSHT (like any DOS program) is 16 bit. It will not run on conventional Widows 7 64 bit unless you have the Professional (I think) version, or as Panars suggests running it in a virtual machine with XP, 32 bit Vista, etc. I do the virtual machine thing with programs like this. 64 bit has...
Some textbooks teach equivalent fluid pressures to analyse lateral earth pressures, so that's where this may have infiltrated into the specification.
I used to teach with a book that did, but I quit both book and equivalent fluid pressures; I found it confusing and my students did also. So...
I have enjoyed and honoured being in this group; unfortunately, I've also been swamped the past several months, and am about to get swamped again. I am not surprised our traffic hasn't been up to speed.
Keep in touch everyone; if you're not getting my sporadic broadcast emails (which means I...
NAVFAC DM 7.01 and 7.02 can be found here:

I would also include this one as well, FHWA's Soils and Foundations Reference Manual...
It's not only still used, but still taught: it's a standard part of any soil mechanics (and lab) course, I'm gearing up for both next semester.
ASCE is using a Proctor test as a student competition for our regional meeting.
It's a tribute to those who developed the core tests of our profession...
Information on the use of Vesic's formula can be found here:

AASHTO, with exceptions, has adopted Vesic's bearing capacity method. It's interesting to note, however, that...
It depends upon whether the "pile" is driven or drilled.
Driven pile reinforcement generally refers to the prestressing strands in concrete piles (or reinforced piles, not often used in the US). There are generally standard arrangements for certain sizes and shapes of piles; you need to...
A list of elastic moduli for various soils can be found in Table 5-16 of this:
http://www.vulcanhammer.net/geotechnical/FHWA-NHI-06-088.pdf
There's also other information on elastic moduli for rock, etc., scattered in the text.
That having been said, they're still correlations, with the...

I don't know how this squares with ASTM, but EM 1110-2-1906 states the following:
"Inspect grooving tools for wear on a frequent and regular basis. The rapidity of wear depends on the material from which the tool is made and the types of soils being tested. Sandy soils cause rapid wear of...
The best way to answer the question "Can I say they are the same?" is "Not really."
Let me explain it in US units, as I'm more familiar with the problem there.
Let's assume that we have a refusal criterion of 120 blows/ft. In theory we could also say 10 blows/inch; however, if we're driving...
Probably the best reference I've got is this:

I also have the Atik and Sitar paper as well.
