Performance Evaluation of Flexible Pavement on Different Subgrades with Industrial Waste

Abstract

Fly ash, an industrial waste with a current utilization rate of about 55%, presents an opportunity for such stabilization. By replacing a portion of the subgrade with fly ash and reinforcing it using bitumen-coated chicken mesh at varying percentages and layer placements, the stability of the pavement can be enhanced. This reinforcement has been shown to significantly improve the California Bearing Ratio (CBR), with maximum strength achieved when 15% of the soil is replaced with fly ash and four layers of bitumen-coated chicken mesh are used. Additionally, incorporating plastic waste into the subgrade at various percentages further affects properties such as Unconfined Compressive Strength (UCS), CBR, Maximum Dry Density (MDD), and Optimum Moisture Content (OMC). These values are calculated in the laboratory and compared with those of unmodified soil to evaluate the improvements in strength and performance.
