Dispersion Tests

Crumb and Double Hydrometer (ASTM D6572 and D4221) tests were performed to screen the material for dispersive characteristics. Additionally, the Pinhole test was requested on specific samples. At the time the testing request was provided to the FW SML, some of the samples had already been extruded and processed. Consequently, the Pinhole test could not be performed on these previously extruded and processed samples.

All three dispersion tests have specific gradation and plasticity criteria, which some samples did not meet. In these cases, the appropriate columns on the ENG-354 are marked with an “NA” for “not applicable”. In general, the soils which do not meet the dispersion test criteria are known to have low resistance to erosion irrespective of their dispersive characteristics.

Crumb test results of 1 indicate that dispersion is not present or is minimal, but results of 3 or 4 are indicators that the clays are dispersive. Crumb Test readings are taken after 1 hour and 4 hours, since some samples have a slower reaction time.

The Double Hydrometer test was used in conjunction with the crumb test to provide a positive indication of dispersion. Double hydrometer results less than about 60 indicate that dispersion is not a problem. The dispersion test results for the submitted samples are summarized below:

* Average of the results for 6A, B and C Per ASTM D4647, ND1 and 2 indicates that the soils nondispersive

The test results indicate that the soils at the site are non-dispersive. The Pinhole test results were comparable to the Crumb and Double Hydrometer results. The only sample with conflicting results was F14-245 in which the Crumb and Double Hydrometer readings did not agree.

In situ Unit Weight and Moisture Content

In situ (natural) unit weights of the samples were determined by trimming off a representative portion of the extruded sample and following ASTM D7263 Laboratory Determination of Density (Unit Weight) of Soil Specimens (clod test). At the time the sample was extruded, a small portion of the sample was also obtained for the natural moisture content.

The natural dry unit weights and moisture contents as well as associated saturation levels are provided in the table below.

Natural moisture contents for the samples listed in the table below were not recorded, nor presented on the ENG-354. These samples were extruded in February 2017 after receiving the sample list and test request. The soils were originally sampled in July 2014; therefore, it was deemed that the moisture contents would not be representative of the in situ conditions. However, upon extrusion the natural dry unit weights were determined per ASTM D7263, since the volume of the sample would not have changed immediately after extrusion.

Collapsibility

Samples with Atterberg Limits and in situ density were plotted on a chart from Holtz and Kovacs (1981, Prentice-Hall). The graph is based on US Bureau of Reclamation experience and indicates whether the material has the potential for collapse or expansion, see Attachment 2. Thirty samples, in the table below, were plotted on the graph and the only sample which indicated a potential for collapse was F14-223. F14- 223 is a silty clay (CL-ML) located at a depth of 17.5 feet to 20 feet at Sta 16+60.

The following non-plastic soils were not plotted: F14-7, -10, -200A, -224A & B, -225, and -243. Table 1 from J. C. Lommler, Ph.D., P.E., D.GE and P. Bandini, Ph.D., P.E.

(2015) provides characteristics of collapse potential soils in the Albuquerque area. The criteria includes in situ dry unit weight, in situ moisture content and degree of saturation, since collapsible soils typically exhibit low density, moisture content and saturation. The criteria in this table was used to determine the collapse potential for these non-plastic soils.
