Abstract

The study explored the improvement in soil performance using quarry waste soil and HDPE geocell reinforcement in layered soil models under varying applied pressures. Quarry waste is a by-product of the quarrying process that includes crushed rock fines, scalping and overburden. It’s often considered waste because of its high clay content, fine particles that make it unsuitable for construction. HDPE geocells consist of a series of interconnected cells from high density polyethylene. These cells are filled with soil to create reinforced structure. Four models were analyzed to evaluate vertical displacement behavior using ABAQUS software: (1) medium dense soil as subgrade and surface soil, (2) medium dense soil as subgrade and quarry waste as surface soil, (3) medium dense soil as subgrade and surface soil with HDPE geocell reinforcement in the top layer, and (4) medium dense soil as subgrade and quarry waste as surface soil with HDPE geocell reinforcement in the top layer. A constant pressure of 100 kPa, 200 kPa, and 300 kPa was applied across all models and the results showed distinct improvement patterns. The model with medium dense soil as subgrade and quarry waste as surface soil exhibited an 80% reduction in vertical displacement compared to the model with medium dense soil as both subgrade and surface layers. Furthermore, the inclusion of HDPE geocell significantly enhanced soil performance under higher applied pressures. The model with medium dense subgrade and quarry waste surface soil, reinforced with HDPE geocell, exhibited a 70% reduction in vertical displacement compared to the model without quarry waste but with geocell reinforcement. The results indicate that while the geocell’s performance is moderate under low stresses, it becomes highly effective under increased loads, providing substantial improvement in load-bearing capacity.
