ASTM WK38106

    New Test Method for Particle Size Anaylsis For Soils Combining The Sieve and Sedimentation Techniques

    (What is a Work Item?)

    Developed by Subcommittee: D18.03 | Committee D18 | Contact Staff Manager


    1. Scope

    This test method covers the quantitative determination of the distribution (gradation) of particle sizes in soils. For particles larger than 0.075 mm (No. 200) sieve, the particle-size (gradation)distribution is determined by sieving. The particle-size (gradation) distribution for particles smaller than 0.075 mm (No. 200) sieve is determined by the sedimentation process. This method applies to soils in which both the coarse and fine fraction particle-size (gradation) distribution is desired.

    This standard is needed to provide a standard in which specifiers can refer to when they want both a hydrometer and sieve analysis on a soil sample. The other two standards are specific to either the hydrometer analysis or the sieve analysis independent of each other. This new combined method allows for on how to perform the testing when both analyses are required on a soil sample.
