    Use of Preliminary Test Piles as Working Piles

    I think that perhaps you can provide examples...For driven piles, the soil ultimate capacity is reached when the pile is driven each blow (unless the set per blow is very small, and only in that case is there extra capacity that has not been activated). So, the capacity of the pile is still...

    @ BigH - Asphalt book

    Hi BigH, thanks for your response to my question about the asphalt book. Sorry, I lost all my emails from the account that I used to communicate with you the last time... could you please send me your email address please?

    Asphalt material book

    Hi ! Can anyone recommend me a good reference book for asphalt materials (design and construction)? I need to do some literature research to answer some questions for an AC pavement that has some surface defects. Thank you !

    Soil movement due to open cut excavation

    I do not do soil modelling... but perhaps the strains for the longer surcharge may be more likely 1-D strains (vertical direction) while for the shorter surcharge, the strains may be more likely 3-D strains. The shorter surcharge acts like a footing. I also agree with EireChch - the extent of...

    Asphalt testing

    Thanks Ron. So basically, the contractor just need to redo the damaged areas...

    Asphalt testing

    We got our lab test results back. Void ratio are high and therefore the densities are slightly lower than the specified. The stability value is about 50% of the specified value which means that the strength of the asphalt is very low (bearing capacity problems??). Do you have any...

    Asphalt testing

    Hi dhengr, we are working with the asphalt contractor but they are not sure about what type of tests can be done to check against this issue. We were thinking on density tests, penetration tests and softening point temperature verification tests but I was looking if anyone has other...

    Asphalt testing

    Not sure about the asphalt surface temperature but the outside temperature was 30 C plus for several days. Looking at the asphalt material properties, the softening point is 46 C. I would expect that the asphalt surface was close to the softening point temperature when this occurred.

    Asphalt testing

    Hi, what could be the best tests to verify the quality of the asphalt? New asphalt was placed 5 months ago but not open to real traffic yet. Client is concerned about tire marks are left on the asphalt. These marks are from steering the wheels without movement. Asphalt is PG 60/80 with...

    Boring Log Software

    Geologismiki was my first option since I am using their CPT software... I will look at the others as well...

    Small-strain vs. large-strain shear modulus - General Bearing Capacity Equation

    I am assuming that the OP is working on pile foundations and using the cavity expansion theory from Vesic...

    Boring Log Software

    Thanks. I checked with Geologismiki but unfortunately the boring logs cannot be exported to Autocad. I would like the boring logs to be exported to CAD so I can add them in the design drawings.

    Small-strain vs. large-strain shear modulus - General Bearing Capacity Equation

    I would use the large-strain shear modulus for foundation design. My understanding is that small-strains are used mostly for seismic applications.

    Geotechnical

    My interpretation is that "half-space" is defined as the space to the boundaries in which an specific solution is not affected. For example, if you look at the settlement of a footing on a soil layer (say a uniform sand), and the footing is circular with a radius r, you can construct the...
