Abstract:

This study investigates the possibility of using waste rocks from coal overburden mining operations (COMWR) as a substitute material for building roads. The objective is to protect natural resources and advance sustainable mining waste management. The objective of the research was to assess the fundamental compaction and physical properties of the material both prior to and following treatment with varying cement dosages ranging from 2% to 8% of its overall dry weight. The findings demonstrated the potential economic viability and utility of the strength gain and COMWR formulation for the subbase and base layers of pavement. With a 6% cement concentration, COMWR may be utilized as a sustainable substitute material for the pavement layer after stabilizing with cement. Moreover, low and high-volume road pavements can employ stabilizing agents in the ratio of 1:4 (COMWR: Cement), in accordance with the IRC SP 89 (Part I) 2010 standards for the use of COMWR in road sub-base and base layers. In conclusion, this research emphasizes how the integration of coal overburden material with cement in highway buildings may lead to both sustainable infrastructure development and efficient waste management in mining operations. When compared to traditional materials, coal overburden material may be recycled to help build safe, long-lasting, and ecologically responsible roadway projects by utilizing the geotechnical qualities and stability benefits it provides.
