Abstract:

In-filled materials play a significant role in performance of trench wave barriers for vibration screening. Using waste materials in trench wave barriers as in-filled materials is an eco-friendly and sustainable step in services and application of geotechnical engineering techniques. But how these materials have suitable application in engineering domain, safety and stability, is an important concern. To know its application and comparison with other materials as in-filled materials in vibration isolation, it is required to ascertain its geotechnical properties. In the present paper, the geotechnical characterization of in-filled materials i.e. rice husk, saw dust and crumbed tyre rubber had been carried out. Several laboratory tests had been carried out such as particle size distribution, specific gravity, bulk density, relative density and permeability. Since trench wave barrier is exposed to dynamic loading, its dynamic properties in addition to these properties are also important. Several dynamic tests had also been conducted such as shear modulus, damping ratio, stiffness and shear strain to curtain down the suitability of these materials as in-filled materials which was used in trench wave barriers for vibration screening. Based on the experimental study for performance of in-filled materials in trench barriers, the results indicate that the materials possessed good characteristics of in-filled materials in trench barrier for vibration isolation.
