Pavements are the unsung heroes of our transportation infrastructure, supporting the movement of people and goods every day. However, traditional pavement design and maintenance practices often come at a cost to the environment and our resources. The need for sustainable solutions in pavement construction and upkeep has become increasingly critical in our quest for a greener and more efficient infrastructure system. One of the primary challenges in pavement design is the environmental impact [1]. Conventional materials like asphalt and concrete, while durable, contribute significantly to carbon emissions during production and are often non-renewable [2]. To counter this, researchers and engineers are exploring alternative materials and innovative techniques.

Incorporating recycled materials such as reclaimed asphalt pavement (RAP) or recycled concrete aggregates (RCA) reduces the demand for virgin materials, cutting down on both extraction and energy consumption during production. [3]Bio-based binders derived from natural resources like vegetable oils or plant resins are being researched as eco-friendly alternatives to traditional petroleum-based binders in asphalt mixes. These binders can decrease reliance on fossil fuels and reduce the carbon footprint of pavements. Regular inspections and early repairs prevent minor issues from escalating, extending the life of pavements and reducing the need for extensive rehabilitation or reconstruction, which consumes more resources [4]. While significant strides have been made in developing sustainable pavement solutions, challenges remain. Balancing cost-effectiveness with sustainability, scaling up alternative materials’ production, and addressing durability concerns are ongoing endeavors. However, ongoing research, collaborations between industry and academia, and policy support can drive innovation and implementation of sustainable practices in pavement design and maintenance [5].

The evolution towards sustainable pavement design and maintenance is imperative for mitigating environmental impact, conserving resources, and ensuring resilient infrastructure [6]. Embracing innovative materials, practices, and technologies paves the way for a future where our transportation systems harmonize with the environment, promoting longevity and sustainability for generations to come [6]. In India waste rubber is mostly used in cold areas to make road pavement more insulating for future aspects.
