2.1 INTRODUCTION

Bulk soil, as it exists in nature, is a more or less random assembly of soil particles, water, and air. The properties of soils are complex and variable. Every civil engineering work involves the determination of soil type and its associated engineering application; certain properties are more significant than others. The common problems faced by civil engineers are related ...
