GEOTECHNICAL INVESTIGATION TESTING METHODS
geotechnical investigation An important basis for the planning and construction of building and infrastructure projects (comprising various types of structures as foundation, excavation pit, land reclamation, beach nourishment etc.) is the knowledge of the ground conditions. For this purpose, the geotechnical investigation with its respective services shall be carried out. Their nature and extent depends on the type of the structure, the difficulty of the structure and the expected ground conditions.

GEOTECHNICAL LABORATORY TESTING WITHIN GEOTECHNICAL INVESTIGATION
Moisture content - determination of the moisture content of a soil as a percentage of its oven-dried weight.
Unit weight - determining the total/moist and dry densities - unit weights - of soil specimens.
Specific gravity - determination of the specific gravity of soil solids passing the 4.75-mm sieve (No. 4) by means of a water pycnometer.
Attenberg limits - determination of the liquid limit, plastic limit, and the plasticity index of soils.
Particle size distribution - quantitative determination of the distribution of particle sizes in soils, distribution of particle sizes larger than 75 μm - retained on the No. 200 sieve - is determined by sieving, while the distribution of particle sizes smaller than 75 μm is determined by a sedimentation process, using a hydrometer.
