Abstract

Safe disposal of recycled construction materials and industrial by-products has become a real environmental concern. Reclaimed asphalt pavements (RAP) and fly ash are such materials, among many other recycled materials, highly produced and stockpiled across the world. The reuse of these secondary materials in civil engineering applications in large quantities is always a challenge due to their inferior properties. RAP materials in pavement base courses have proven to be a viable alternative not only to conserve the natural resources but also to reduce the environmental pollution and landfilling. Since RAP is inefficient to be used as a pavement material, they are blended with virgin aggregates (VA) or stabilized with cementitious materials.
