3 Objectives of Soil Mechanics To perform the Engineering soil surveys. To develop rational soil sampling devices and soil sampling methods. To develop suitable soil testing devices and soil testing methods. To collect and classify soils and their physical properties on the basis of fundamental knowledge of soil mechanics. To investigate the physical properties of soil and
Soil Map Units A soil map unit is a collection of areas defined and named the same in terms of their soil components (e.g., series) or miscellaneous areas or both –Fallsington sandy loam, 0 to 2% slopes –Marr-Dodon complex, 2 to 5% slopes Soil map units are the basic unit of a soil map Each soil map unit differs in some

A digital concrete hammer, model 58-C181/F, made by Controls with an impact energy of 2.207 joules was used. This model complies with the following stan-dards: ASTM C 805, UNI 9189-88, BS 1881, NF P18-417, DIN 1048, ISO/DIN 8045. A well-calibrated ham-mer of these standards is expected to generate the same readings as presented here. Hammer readings were determined on samples of the following .
