Compressibility of Fly Ash and Fly Ash-Bentonite Mixtures

open access: yesThe Baltic Journal of Road and Bridge Engineering, 2022
Environmental protection, one of the most important issues nowadays, forces civil engineers to look for alternative solutions to the known ones. The use of substitute materials as an embankment fill or a ground material under the embankment instead of natural soil follows these trends. A great amount of fly ash is disposed of in landfills. It is a cost-
