Study of Stoneworks Waste (Mudstone) Effects on Geotechnical Porperties of Dune Sand

Nowadays, the Iran country with considering huge reserves of building stone, is one of the important countries in world. But, unfortunately when building stones are processed in factories, significant part of material changed to waste. In final of processing, simultaneous national treasures are spoiled and environment is damaged too. Therefore, propose new methodologies and reuse of waste materials due to building stone is necessary. In this research, main idea is study of mudstone due to travertine and granite on geotechnical properties of dune sand. In present research, some factors such as optimum water content, dry density, bearing capacity, internal friction angle and cohesive by using laboratory tests including compaction, California Bearing Ratio (CBR) and direct shear tests were evaluated.
