Abstract - The infrastructure of highways, particularly the
generation. This surge raised environmental concerns due to the hazardous materials present in electronic products, such as heavy metals and toxic chemicals. As environmental awareness grew and waste management efforts intensified, researchers and engineers began exploring alternative applications for e-waste. One promising area that emerged was its potential utilization in civil engineering, notably in pavement construction. The notion of integrating e-waste into pavement materials gained traction in the early 21st century as the need for sustainable infrastructure solutions became more apparent. Early studies focused on understanding the characteristics and properties of e-waste and its suitability for pavement applications. Researchers explored various methods for processing and integrating ewaste into pavement mixtures, including shredding, grinding, and blending with traditional aggregates and binders. Through laboratory experiments and pilot projects, they evaluated the mechanical, chemical, and environmental performance of e-waste-modified pavements.
pavement, is crucial for efficient transportation systems and economic progress. However, conventional pavement materials often have limitations in terms of strength, durability, and sustainability. Recently, there has been a growing interest in exploring alternative materials to improve pavement performance and lessen environmental impact. One promising approach is the use of electronic waste (e-waste) in pavement construction. This review critically evaluates the potential of integrating e-waste materials into highway pavement to enhance its strength and durability. It consolidates existing literature on the characteristics, composition, and properties of e-waste, as well as various techniques for its integration into pavement materials. The review underscores the advantages and challenges of utilizing e-waste, including its capacity to bolster pavement strength, diminish environmental pollution through waste diversion, and alleviate the depletion of natural resources. The paper discusses the effects of incorporating e-waste on pavement performance, encompassing its influence on structural integrity, stiffness, fatigue resistance, and rutting behavior. Environmental aspects such as leachability, toxicity, and long-term sustainability are also addressed. By conducting a comprehensive analysis of current research findings and case studies, this review offers insights into the feasibility and potential benefits of employing e-waste in highway pavement construction. It identifies knowledge gaps and proposes areas for future research to optimize the utilization of e-waste in pavement engineering. This review underscores the importance of integrating innovative materials like e-waste into pavement construction practices, thereby contributing to the development of sustainable and resilient transportation infrastructure systems.
Advancements in materials science and pavement engineering techniques facilitated the development of innovative approaches for integrating e-waste into pavement designs. Researchers investigated using e-waste as a partial replacement for conventional aggregates, fillers, or additives to enhance pavement strength, durability, and sustainability. As research progressed, numerous studies demonstrated the potential benefits of incorporating e-waste in highway pavement construction, including improved mechanical properties such as increased compressive strength, enhanced resistance to fatigue and rutting, and reduced susceptibility to environmental degradation. The incorporation of e-waste into pavement construction also provided environmental benefits by diverting hazardous waste from landfills and reducing the depletion of natural resources, aligning with broader efforts towards circular economy principles and sustainable development goals. In recent years, there has been growing interest from governments, transportation agencies, and industry stakeholders in promoting the adoption of e-waste-modified pavements as part of sustainable infrastructure strategies.
