SIMPLIFIED IN-SITU METHOD FOR SOIL IDENTIFICATION

METODO SIMPLIFICADO DE CAMPO PARA IDENTIFICACION DE SUELOS

The identification of soils is carried out using a number of characteristics easy to evaluate and quick to measure, which give a general idea before a later classification. In coarse soil the characteristics to be observed are: mineralogy, hardness, shape of grains, degree of meteorization, permeability, internal friction angle and aptitude to wear. In fine soil cohesion depends on various parameters: specific surface, shape of the mineral grains and type of structure. For this type of soil the method of identification is based on the capacity of the soil mass for water retention, e.g., the time necessary to go from the estimated moisture content near the liquid limit to the plastic limit by manual mixing. It is thus possible to obtain a series of characteristics such as: absorption, retention capacity, expansion capacity and compressibility. (TRRL)
