Abstract

The determination of particle size distribution (PSD) is one of the most important fundamental physical properties of soils, which determines both the physico-chemical, mechanical, geotechnical, moreover environmental behavior of the sediments. Although the measurement of PSD is frequently performed in soil labs using different techniques there are two important problems to solve: automation and continuous PSD curve generation. To overcome the mentioned troubles the new, hydrostatic method of continuous particle size distribution measurement was introduced, and also a new evaluation method (the method of finite tangents) was developed. To prove the developed methods both for soil testing and measurement evaluation the pilot test equipment called ASTA was built. The measurements shows that the hydrostatic method is suitable for the measurement of PSD curves, the accuracy of measurements using ASTA device was adequate to the measurements with the traditional hydrometer method.
