RIVER SEDIMENT AS ROAD MATERIAL

At the bottom of the canal, there are large deposits of silt. During the cleaning and scouring of the river bed, so-called by-product sediments are formed. Landfills are made along the river bed because it is a relatively close distance. During the preparation of this paper, the idea refers to the examination of sediment with additional binders to see its application in the road industry. The tests that will be presented in the paper are: the granulometric composition of the soil, determination of the maximum volumetric mass at optimal humidity (Proctor's test), determination of the soil's bearing capacity using the California Bearing Index, determination of uniaxial compressive strength after 7 and 28 days and indirect tensile strength after 28 days. The used binders are cement and lime with fly ash and other mineral additives. After the analysis, the cement binder showed slightly better results than the lime binder because the material has its natural humidity.
