Abstract

This research examines the utilization of oil-contaminated sands (OCS) in pavement building to tackle environmental and economic challenges. Hydrocarbon contamination alters the geological and physical properties of oil sands, an underexploited resource. This study investigates the impact of OCS on sand density, permeability, shear strength, and plasticity, which influence compaction and stability. The study will standardize the classification of OCS to facilitate road development. Oil sand combined with diverse fine aggregates is evaluated to improve mastic compositions for patching in low-traffic, tropical roadways. Density, triaxial strength, compaction, and petroleum hydrocarbon analysis were conducted to assess the potential usage of treated OCS in asphalt mixtures. The results should demonstrate that the incorporation of OCS minimizes waste and landfill disposal while offering a cost-effective binder alternative for pavement construction. The study aims to identify optimal mix proportions that reconcile strength and durability, facilitating cost-effective and sustainable road infrastructure solutions.
