Geo technical Laboratory Evaluation of Construction Demolition Recycled Material for Road Embankments

Abstract

The recycling of construction demolition waste material has already become a prime focus under sustainable technologies and innovations across the globe. A report announced by the Centre for Science and Environment (CSE), Delhi, in August 2020 stated, India generates approximately 150 million tons of construction demolition waste every year and recycles only 1%. The rest remains strewn across, in landfills causing air contamination and water tainting. Whereas "The United States Environment Protection Agency (USEPA)"approximated that 600 million tons of construction waste had been generated in 2016 in the USA, around 75% of the waste was recycled and also used effectively. The present paper focuses on predicting the suitability of recycled construction demolition waste material for road embankment and comparing its characteristics with conventional embankment materials. The Guidelines given by IRC and BIS were following to predict the feasibility of recycled construction demolition waste as fill material for road embankment. Laboratory results indicated the suitability of recycled construction demolition waste material for road embankments. This study probed a single source of construction demolition waste with one particular gradation as it can significantly alter the properties and suitability requirements.
