and depths ofpits, trenches, or borings shall be in accordance with the professional judgment of the Qualified Registered Professional of record. 2.3 En ' Bering, Properties of Soil. The engineering, or physical, properties of soil and rock depend on both the material, or grain, properties (see Level 2 above) and the in-situ, or undisturbed, texture, packing, particle orientation, and degree of saturation. Shear strength, compressibility, permeability, and erodibility are the engineering properties of interest. Tests for estimating the in-situ sheaz strength, and indirectly the compressibility, of a soil aze of two types: (1) direct tests, that attempt to measure the shear strength by direct simulation of field loading conditions and (2) indirect test that aze used with empirical correlations to estimate sheaz strength in terms of relative consistency (cohesive soils only) and relative density (clean granulaz soils only). Field tests for measuring the permeability of an aquifer may be made using pumping out tests or slug tests. Any one, or a combination, of the following tests or procedures may be made to determine or estimate sheaz strength properties of the various soil types and deposits encountered in the test borings or test pits. 2.3.1 Direct measures of in-situ sheaz strength include: 2.3.1.1 Plate Load Test (ASTM D1194). 2.3.1.2 Field Vane Sheaz Test (VST). of Cohesive Soil (ASTM D2573). 2.3.1.3 Borehole Sheaz Test (BST). 2.3.1.4 Unconfined Compression Test of Undisturbed Cohesive Sample (ASTM D2166). 2.3.1.5 Hand Penetrometer Test of Cohesive Sample (Used only .for secondary evaluation). 2.3.2 Indirect, empirical estimators of in-situ sheaz strength are: 2.3.2.1 Standard Penetration Test (SPT) (ASTM D15S6). . 2.3.2.2 Static Cone Penetration Test (CPT) (ASTM D 3441). 2.4 In-Situ Chazacter of Rock. The engineering characteristics of an in-situ rock mass generally are concerned with its structural elements.. Discontinuities. aze the major elements of in-situ classification. Fractures in exposed rock surfaces aze described in terms of frequency, attitude, spacing, roughness, bonding quality, and general continuity. The main tests made on rock cores, taken with a diamond core barrel sampler, aze: 2.4.1 Unconfined compressive strength and/or point load strength. 2.4.2 Rock Quality Designation (RQD). 2.4.3 Seismic velocity and/or velocity index. 3.
