  • Leaching Characteristics of Recycled Asphalt Pavement

    solutions. Concrete made with waste aggregates has significant limitations in strength particularly flexural strength which is the main parameter of quality control and design for concrete pavement. It is therefore not practical to use waste aggregates for the surface layer of concrete without using additives or special treatments.
