MODIFICATION OF CLAYEY SOILS’ PROPERTIES WITH THE ADDITION OFLIME AND FLY ASH
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 30, Vol 5, Issue 10
Abstract
Samples of swelling soils from sites in Rhodope Peripheral Unit (former prefecture) were stabilized using limeand fly ash and the alteration of engineering properties such as the plasticity, the relation between moisture anddensity and the compressive strength has been investigated in the laboratory. It is established that lime is a verygood stabilizer, acting beneficially not only on the strength characteristics, but on the optimum moisture andmaximum dry density as well. The pozzolanic properties of the fly ash are mainly responsible for theimprovement coming upon the characteristics of the tested soil materials. The role of specimen’s curing time isimportant, more specifically in the case that lime is used as additive. By investigating a large number of soilmaterials, it is feasible to establish suitability criteria for their use in stabilized subgrade and roadway layers.
