<p>This study explores how to enhance low-volume roads by using geocell reinforcement with mine waste materials from the Banegaon and Umrer open-pit mines.

摘要

This study explores how to enhance low-volume roads by using geocell reinforcement with mine waste materials from the Banegaon and Umrer open-pit mines. It evaluates the California Bearing Ratio (CBR) of subgrade layers reinforced with single-pocket and double-pocket geocells. Materials from Umrer mines performed better, achieving CBR values of 35.22% (unsoaked) and 21.97% (soaked) with double-pocket geocells, compared to the Banegaon mine waste, which showed CBR improvements to 31.19% (unsoaked) and 16.96% (soaked). The study uses the Improvement Factor (If), a non-dimensional parameter, to assess the benefits of geocell reinforcement. The highest Improvement Factors observed were with double-pocket geocells, reaching 2.04 for Banegaon mine materials and 2.11 for Umrer mine waste, indicating substantial enhancements over the traditional method, which had CBR values of 19.78% (unsoaked) and 11.58% (soaked). The results emphasize the importance of geocell placement, particularly at one-third of the top layer, utilizing the tensioned membrane effect to effectively resist vehicle loads. Additionally, the research highlights that moisture conditions affect CBR values, with significant reductions under soaked conditions, but these reductions are mitigated by geocell reinforcement. Overall, this study demonstrates that the use of geocell reinforcement, particularly with materials from the Umrer open-cast mine, can significantly improve the durability and load capacity of low-volume roads.
