    Major Shrinkage?

    I apologize, you are correct shelby tubes do not work in sands, I read soft and automatically assumed fine-grained. However in sands it may be possible to use CPT testing to determine a consolidation parameters. Here is a link that describes a SCPT...

    Asphalt Millings Structural Coefficient for Pavement Design

    Sounds like it held up well.... I would also be interested in millings for beneficial reuse.... thanks for the reply.. [bravo] Keithe J. Merl

    Buttress Dams Stability Anaylsis

    Good suggestion, from my knowledge it is solid concrete, however more research is to come. We may be getting some pictures from the original construction.... Keithe J. Merl

    Rock Wall Evaluation

    Here is a source form the army corps of engineers for engineering with large stones, it may help: http://www.usace.army.mil/publications/eng-manuals/em1110-2-2302/entire.pdf [bravo] Keithe J. Merl

    Buttress Dams Stability Anaylsis

    Focht3 Thanks for the link I will research soe of those articles. The dam you are describing is similar, however much bigger scale (ours is smaller). From the research to this point there is no hollow portion, it is a solid structure the maximum height from ground surface is approx. 14ft...

    Rock Wall Evaluation

    Well look at the local standards, did you check the other thread there, I think there is some national codes refered there. Fifteen feet high is rather large for a dry rock wall. Remember that these walls to rely on gravity to determine the stability. You act as though the wall is one...

    Rock Wall Evaluation

    Also refer to thread: thread255-82018 This has some very useful information... [bravo] Keithe J. Merl

    Rock Wall Evaluation

    Well I think the largest problem with these walls in storm events relates to several things. The tractive forces removing rocks from overtopping, hydrostatic forces on each rock unit, and the global. So to get started you need to determine if there was a reason for failure, was a small rock...

    Buttress Dams Stability Anaylsis

    Thank you cap4000 That sounds like how I have to consider this, i.e. it is a series of counterfort concrete structures in series. That sounds like a great analogy.... [bravo] Keithe J. Merl

    Buttress Dams Stability Anaylsis

    Focht3 If you me open faced slab buttress type dam, you are on the right track. I have been pondering this issue over the weekend and have come up with an idea. By the way... This site is located in Princeton, New Jersey. It is exisitng, it is located at Carnegie Lake. I have very limited...

    Buttress Dams Stability Anaylsis

    I have a project involving a buttress dam. The dam is founded on shales, I need some references for the determination of stability values. Slide, foundation, overturning, etc. One of the main issues is interaction of the "thin" section with buttress section and the loading that each...

    Excavated dirt & mud storage challenges!!!

    If the material is to be piped to a disposal location can you construct a containment area by using the materials excavated and then filling in between. Like a sludge containment pond... Another method may be to use geotextile tubes to store the materials, however they specific types and...

    Asphalt Millings Structural Coefficient for Pavement Design

    jimbo, Have you had a chance to revisit the pavement recently to see how it is currently holding up? Keithe J. Merl

    Stability Calculations of Buttress Dams

    I am in search of guidence on calculations of global stability as it relates to butress dams. I have a project involving a buttress dam founded on shales and would like to gain more sources for determination of sliding, overturning, foundation failure, and other stability modes. Keithe J. Merl

    Asphalt Millings Structural Coefficient for Pavement Design

    jimbo.. Did you complete any testing on the asphalt materials while being placed. I would be interested to see the denistyies and viod ratios acheived during placement. Also how thick was the recycled asphalt placed? I have used recycled concrete ,locally call 2RC, and have had great success...
