Recycled Materials from Road Demolition Wastes Used in Pavement Construction

The construction industry generates significant amounts of demolition waste, particularly from road construction and rehabilitation projects. Recycling these materials into new pavement structures presents an opportunity to reduce environmental impact and conserve natural resources. This paper explores the use of recycled materials from road demolition, such as reclaimed asphalt pavement (RAP), recycled concrete aggregate (RCA), and other construction and demolition (C&D) waste, in pavement construction. The benefits, challenges, and implementation strategies are discussed, along with the impact on cost, durability, and sustainability. Additionally, this paper highlights case studies and real-world applications demonstrating the effectiveness of recycled materials in modern pavement construction.
