Abstract


The paper evidences preliminary research results on the process of vibratory compaction of soils for sustainable road construction. For an efficient process, one important aspect is that of determining soils characteristics, out of which compressibility behavior is relevant. An innovative loading device for the oedometer test has been designed so that to enable efficient loading of soil samples - with minimum effort and complex data processing of the results. Further, Kelvin-Vogt model of the viscoelastic rheological behavior of soil has been considered for in situ research. The obtained experimental data and their associated mathematical models, as well as the plotted graphs would be applied for optimum soil’s vibratory compaction process. Related to the mentioned aspects, there has been conceived a Romanian fit control plan for sustainable road construction.
