Abstract Recently, the use of plastic products, such as polyethylene (PE) bottles and polypropylene (PP), has been significantly increased, which may lead to many environmental issues. Therefore, it is important find methods manage these waste materials without causing any ecological hazards. One wastes soil stabiliser materials. In this study, PE PP have used in form fibres. The effect stabili...

The modulus of elasticity represents the soil stiffness; it was used to design and analyze foundation, slope stability, retaining structure, etc. It is one main input parameters in finite element method for analyzing behavior. scope this study evaluate correlation between (E) cohesion (c u ) remolded undisturbed samples clayey so can assess effect lateral confining pressure on elasticity. uncon...
