    metal material supplier???

    Not to mention Bellefonte - I bet TVA might just give the parts away for free!

    Florida Nuclear Plant Contract

    As someone who is in the know on this one, the project will go in Levy county and is well underway. Progress Energy cannot build any further unit as the Crystal River site, and chose the Levy County site after a year-long site selection process that looked at at least 3 other sites in Florida.

    nuclear density gauges are not accurate

    I know I am late to the party here - but I dodn't see where anyone mentioned the use of a one-point proctor to aid the technician in his selection of the most appropriate laboratory proctor. I agree that it does require the techcnician to take more equipment in the field, and there is always...

    PROCTOR VALUES FOR DIFFERENT SOILS CLASSIFICATIONS

    I agree with msucog - here in the eastern piedmont in North Carolina we see maximum dry unit weights in soil that range from roughly 80 pcf up to 135 pcf, and we have some well graded stone and soil mixes we use for roadbase that can get up to 155 pcf. I am quite sure in other geologies you...

    Troxler and Humboldt gauge? Price, etc.

    The last time I priced a Troxler 3450 - it was around $8,000 US brand new with the first calibration and leak test having been done before it was shipped. That did not include any shipping charges, but I am only 20 miles from their facility in Research Tiangle Park, NC. I know the shiopping...

    Asphalt Compaction Issue

    Depending on the manufacturer and model of the nuclear density gauge you are using, there is sometimes a correction factor that can be put into the gauge itself. More specifically, I know that the Troxler 3440 will do the correction for a "thin lift" of asphalt (which I believe Troxler defines...

    Cost of CPT vs. SPT

    Well - If this is of any interest to you (meaning dgillette and KVgeo), my hope in having CPT (or SCPT) performed was so that I could have multiple data sets to compare. I have a good ammount of SPT data using calibrated hammers from borings performed using drilling mud - but I do have concerns...

    "compaction" tests in residuum

    I think there is a very easy way to summarize most of what has been said here - compaction testing in residual soils (which are indeed soils that come from the in-place weathering of the parent rock material) is not the proper way to evaluate their strength or ability to carry building loads -...

    Large Fill Site

    I think that you might be onto a good idea with the rammed-aggregate pier system. Not only do you get some end bearing from the piers - but you will see improvement in the surrounding soils from the compaction process.

    Cost of CPT vs. SPT

    It's funny you should mention Paul Mayne - I met Dr. Mayne last year and I have already been in discussions with him via email regarding the project. I would agree with your thoughts on the seismic cone.

    Cost of CPT vs. SPT

    I am trying to get my bosses to approve some CPT work at a project site where we have concerns over luiquefiable soils. Wwe have plenty of SPT data, as well as shear wave measurements. We feel that we have characterized the site in general and now we need to fill in the gaps. I am proposing...
