SUBSURFACE SOILS EXPLORATION
This manual attempts to give the county engineer a basic understanding of the need for subsurface soil exploration, a review of the techniques currently available, and proper field and office procedures for logging, recording and interpreting data. Pointers are given on planning the soil investigation process, followed by a brief review of the properties of soils and their strength values for design process. The conduct of the exploration is then detailed, this covers aspects such as locating and sampling borings, sampling procedures and technqieus, field identification of soils, soil classification systems, and field identification of rock. Reporting of 6 types of subsurface exploration information is discussed: graphical presentations of soil borings; special use of materials or potential problems areas; photographs of land forms; profiles of surface and subsurface materials; properties, strength and grading; and unusual problems and recommended solutions.
