  • ASTM D6066 - 11 Standard Practice for Determining the Normalized Penetration Resistance of Sands for Evaluation of Liquefaction Potential

    Normalization of penetration resistance data is a frequently used method to evaluate the liquefaction susceptibility of sands. A large case history database from many countries has been accumulated to estimate instability of saturated sands during earthquakes (1,2,3,4). This test is used extensively for a great variety of geotechnical exploration programs where ...

  • New Concrete Scanning GPR Systems

    It seems the trend in ground penetrating radar concrete scanning systems is to go smaller, lighter and more portable. These are all positive benefits for these new smaller systems. However, these benefits may come with a few compromises. The new “Mini” concrete scanning GPR systems featured in this blog are from two leading GPR system manufacturers Sensors & Software and GSSI. We ...

  • ASTM D6429 - 99(2011)e1 standard guide for selecting surface geophysical methods

    This guide applies to commonly used surface geophysical methods for those applications listed in Table 1. The rating system used in Table 1 is based upon the ability of each method to produce results under average field conditions when compared to other methods applied to the same application. An “A” rating implies a preferred method and a “B” rating implies an alternate ...
