    Wet Ball Value or L.A. Abrasion Testing Alternatives

    We have a client requesting a wet ball value (TXDOT TEST METHODS 116-E) or, as an alternative, an LA Abrasion Test. The problem is they don't have enough material to run either test. Are there any other tests out there that would yield similar information with a smaller sample size (6000 grams...

    Buried Power Cables

    DPC, I am curious as to where the typical values come from. Are they based on soil classification, atterberg limit tests on the soil, density, watercontent? If not field tests, is it common practice to take specimens from the field and send to a lab for actual numbers? Again, thanks much for...

    Buried Power Cables

    I am in the geotechnical field and was curious as to where electrical engineers are finding testing for the thermal resistivity of soil, and how they found their lab of choice...search engine, etc. Thanks much

    Direct Simple Shear Testing, ASTM D6528

    We are strictly a soil mechanincs laboratory. We don't do any engineering, our clients are geotechnical engineers. Consequently, we don't need the results ourselves. We have one client who has said they would like us to invest in this equipment; however the equipment is quite expensive and...

    Direct Simple Shear Testing, ASTM D6528

    I am trying to decide between various pieces of equipment to purchase for our soil mechanics laboratory. One piece of equipment we are looking at is a direct simple shear. I am curious as to what kind of demand is there for this test. I haven't been able to find too many labs offering this...

    Thermal Resistivity Testing...Buried Power Lines

    We have a client interested in having us run thermal resistivity tests on 3 inch thin wall samples. The ASTM standard D5334 gives the procedure for determining the thermal resisitivty at a given moisture content and it's fairly straight forward. My question is would engineers want the...

    Torsional Ring Shear Is There Demand

    I work with a small soil mechanics laboratory, and we are considering purchasing a torsional ring shear machine. This device would determine the drained residual shear strength of cohesive soils as per ASTM D:6467. I would like feedback on the quality of results, and on demand... is there a...
