 Density and Unit Weight of Soil

Standard Test Method for Density and Unit Weight of Soil in Place by the Rubber Balloon Method

SCOPE

This test method covers the determination of the inplace density and unit weight of compacted or firmly bonded soil using a rubber balloon apparatus. This test method is suitable for use as a means of acceptance for compacted fill or embankments constructed of fine-grained soils or granular soils without appreciable amounts of rock or coarse material. This test method also may be used for the determination of the in-place density and unit weight of undisturbed or in situ soils, provided the soil will not deform under the pressure simposed during the test.

Standard Guide for Using the Seismic Refraction Method for Subsurface Investigation

Scope

Purpose and Application—This guide summarizes the equipment, field procedures, and interpretation methods for the assessment of subsurface conditions using the seismic refraction method. Seismic refraction measurements as described in this guide are applicable in mapping subsurface conditions for various uses including geologic, geotechnical, hydrologic, environmental (1), mineral exploration, petroleum exploration, and archaeological investigations. The seismic refraction method is used to map geologic conditions including depth to bedrock, or to water table, stratigraphy, lithology, structure, and fractures or all of these. The calculated seismic wave velocity is related to mechanical material properties. Therefore, characterization of the material (type of rock, degree of weathering, and rippability) is made on the basis of seismic velocity and other geologic information

Standard Test Method for Performing Electronic Friction Cone and Piezocone Penetration Testing of Soils

Scope

This test method covers the procedure for determining the resistance to penetration of a conical pointed penetrometer as it is advanced into subsurface soils at a slow, steady rate. This test method is also used to determine the frictional resistance of a cylindrical sleeve located behind the conical point as it is advanced through subsurface soils at a slow, steady rate This test method applies to friction-cone penetrometers of the electronic type This test method can be used to determine pore pressure development during push of a piezocone penetrometer. Pore pressure dissipation, after a push, can also be monitored for correlation to soil compressibility and permeability
