    Specification for Organic Content in Fill

    Thanks. Material in question came in at 3% and I was thinking a 2% limit was too strict but 5% seemed a bit too lax. So that 4% limit works for me. I'll consider your response standard of practice :). Kidding. But if anyone else has a comment I'd be interested.

    Specification for Organic Content in Fill

    What do you consider a reasonable maximum organic content to specify for engineered fill placed under a building foundation? Material in question is a silty clay bordering on a silt. I am expecting 0 to 6 feet of fill under the footings (ie depth varies). 2 story wood frame construction for...

    determining c and phi for clay fill

    LL = 32 to 37 and PL = 12 to 17 so it is a good stiff to very stiff lean clay. Placing as fill to 95% standard proctor is my trouble. I'm mulling about how do I assign parameters. I don't have the comparative luxury of triax testing (sigh... such is life). I think the above numbers are...

    determining c and phi for clay fill

    I have a cut/fill site in clay. I need to look at short and long term slope stability. The clays are quite stiff with unconfined values of about 5,000 to 7,000 psf and N=16 to 20. Moisture contents are 16% to 18%. My short term analysis will use 1,500 psf cohession and 0 friction. The...
