1.1 These methods cover the determination of the quality of soil samples by X-ray radiography.

1.2 These methods enable the user to determine the effects of sampling and natural variations within samples as identified by the extent of the relative penetration of X rays through soil sampl...

1.1 This test method describes the procedure for measuring that part of the drive weight (hammer) kinetic energy that enters the penetrometer connector rod column during dynamic (hammer impact) penetrometer testing of soil.

1.2 This test method has particular application to the comparati...

1.1 This practice is intended for use as a summary of nondestructive quality control test methods for determining the integrity of seams used in the joining of flexible sheet materials in a geotechnical application. This practice outlines the test procedures available for determini...

1.1 This guide covers the material characteristics, physical requirements, and sampling appropriate for the designation of the material as a mineral amendment.

1.2 The presence in the topsoil of the correct nutrient and pH level is necessary for healthy plant growth...

1.1 This test method provides an index to the expansion potential of compacted soils when inundated with distilled water.

1.2 This test method controls variables that influence the expansive characteristics of soils and still retains a relatively simple test for practical engineer...
