Abstract

Sustainable development encourages the use of waste as an alternative material in infrastructure, including on road pavement. This study evaluated the performance of Laston Coated Wear (AC-WC) asphalt mixture with the substitution of glass waste as fine aggregates in variations in 0%, 10%, 20%, and 30% levels. Material characteristics testing as well as Marshall tests and residual stability were carried out referring to the General Specification of Highways Division 6 of 2018 Revision 2. The results show that the glass waste meets the technical specifications as a fine aggregate. Blends with 10% glass content produce the highest Marshall stability value of 93.4% and the best overall performance. The Optimum Asphalt (KAO) content has increased as the glass content has increased, but it remains below the normal mix KAO. Mixing with glass also shows good water resistance. Therefore, a 10% glass waste substitution is recommended as an alternative to fine aggregates in AC-WC mixtures to support environmentally friendly road infrastructure.

Abstract

The rapid pace of urbanization has increased the demand for environmentally friendly and energy-efficient urban road infrastructure. However, the use of conventional construction materials contributes to ecosystem degradation and carbon emissions. This study aims to optimize the use of eco-friendly materials in urban road construction to support sustainable development and energy efficiency. A qualitative literature review approach was employed to examine relevant scientific sources, including journals, books, and policy documents. The data were analyzed using content analysis to identify patterns and the contributions of eco-friendly materials to energy efficiency and carbon emission reduction. The findings indicate that materials such as recycled concrete, eco-friendly asphalt with bio-based binders, and pollution-absorbing paving materials have significant potential in enhancing energy efficiency and reducing carbon emissions in urban road construction. Several cities, including Tokyo, Los Angeles, and Paris, have begun adopting these approaches in their infrastructure projects. This study recommends the adoption of recycled materials, bio-based binders, and eco-friendly paving technologies as key strategies in developing sustainable road infrastructure. The practical implications of this research include long-term energy savings, reduced maintenance costs, and improved urban environmental quality.
