The paper investigates typical Baltic sea-shore sand along Klaipėda and diagnoses the level of particle crushing after different loading steps. An oedometer test is done applying to drained loose (eo = 0,764) and dense (eo = 0,604) sand. The used loading steps are 0,0; 200,0; 400,0; 600,0; 800,0 kPa. Investigation into the level of particle crushing is made conducting a sieve test employing spherical balls on the sieves of a different size. The sieve test is done following different loading levels. The results of the grading curve show that 800,0 kPa vertical stress does not crushes the particles of the oedometer sample. The analysis of the compression results of loose and dense sand shows that a determined immediate settlement of sample appears when vertical stress makes from 50,0 kPa to 120,0 kPa and where immediate settlement values do not belong to the density of the sand sample. For investigation purposes, the equipment and infrastructure of Civil Engineering Scientific Research Centre of Vilnius Gediminas Technical University were employed [ABSTRACT FROM AUTHOR]
