Strength Characteristics of Gravel-Flyash Reinforced with Waste Fibers

Flyash is a waste produced from thermal power stations, which contributes to environmental pollution. It is waste materials that can be utilized in construction of roads and embankments. Disposal of a variety of wastes in an eco friendly way is the thrust area of todays research. Randomly distributed fiber reinforced soils have recently attracted increasing attention in geotechnical engineering. These soils are prevalent as large tracts in many parts of the world. Many highway agencies, private organizations and researchers are doing extensive studies on waste materials and research projects concerning the feasibility and environmental suitability. It is necessary to utilize the waste affectively with technical development in each field. Attempts are made to investigate the stabilization process with laboratory model test tracks over expansive subgrade. Compaction, Shear and CBR tests were carried out in gravel/flyash materials with different reinforcement materials like waste plastics and waste tyre rubber with a view to obtain optimum percentage of reinforcement materials.
