Utilizing different wastes in rural roads of Karad, District – Satara, India

Abstract

The rural roads in India comprise of village roads (VR) and other district roads (ODR). The traffic intensity is taken as 2 million standard axles (msa) since traffic load has increased on the rural roads. The design guidelines have recommended the utilization of wastes accessible in the nearby vicinity for road construction. Effective disposal of wastes such as plastic, rubber and electronic waste is the main concern in India. The adverse effects of these identified wastes could be put to a beneficial use if utilized in road construction. Due to the increasing trend of heavy traffic on rural roads, a bituminous Macadam layer is generally laid over granular layers of the pavement. As such, the primary objective of the research is to discover the optimum content of using the identified wastes to replace bitumen and aggregates of rural roads. Numbers of laboratory tests have been carried out on modified mixtures to understand the aptness and optimum content of the wastes in construction of rural roads. The strength property of the naturally available soil was studied for the rural roads in Karad. The California bearing ratio test analysis and their outcomes were employed to assess the strength of the subgrade in the study area. Further, based on the suitability of identified wastes in bituminous layer, IITPave software was used to analyze the performance of rural roads of the study area. Using the IITPave software, design charts were created based on utilizing the wastes for rural roads in Karad, District – Satara, India.
