stabilization, alter and improvement of engineering properties of soil are for providing predetermined goals. the most important aim of soil stabilization is increasing long term soil strength, but in very wet and loos lands the other aim of soil stabilization, is to decrease plasticity characteristic of soil, which are tested by atterberg limits tests. since the road soils of namkhane district...

Subgrade soil stabilization is one of the primary and major processes in the construction of any highway; also environmental authorities are concerned about the growing amount of polyethylene (PET) bottles produced by household sectors. This research in order to study effect of adding recycled polyester fiber on soil engineering properties, especially shear strength and California Bearing Ratio...

Usability of scoria waste as subbase stabilization material was investigated. Initially, the physical properties were examined. The usage in layer pavement In study, experimental researches such stability to freeze, solidity, strength, Atterberg limits and California Bearing Ratio tests carried out on samples prepared by using waste. Scoria natural quarry materials blended different amounts pro...

<p>This study utilized a series of experimental tests, including the Atterberg limit, standard Proctor, permeability, and direct shear tests. Three composites were investigated: 85% fly ash-10% bentonite (V1), 90% ash-5% (V2), 95% ash-0% (V3). All contained 5% coconut fiber. The plasticity index (PI) increased significantly from 19.10% to 22.15%, with change in content 0% 10%. composite m...
