Recycled Aggregates in Highway Pavement

A comprehensive research was performed on application of demolished construction wastes in road pavement layers. The research succeeded in cataloging the specifications of recycled aggregates mixes for practical works, followed by development and evaluation of different mixes of recycled aggregates obtained from different sources. Detailed assessment based on compliance with requirements, performance prediction and modeling was completed. Evidently the research is likely to have a number of implications on the design and construction of highways. Firstly, the demonstrated viability of mixes containing recycled materials can lead to significant cost savings, reduced carbon footprint, reduced exploitation of virgin materials and minimization of dumping of civil engineering waste. If embraced in industry, the suggested use of recycled materials can help support national and international targets regarding sustainability, environmental and energy conservation.
