Abstract

In the light of carbon-neutral society and circular economy, attempts were made in this study to utilize the waste foundry sand (WFS) in high volume as a pavement construction material. A series of laboratory tests, including but not limited to particle size distribution, Proctor, pH values, shear box and compressive strength test were performed to investigate the technical soundness of the material. Insufficient strength of the stabilized WFS has promoted the utilization of a mixture containing not only WFS but also quarry fines. The compressive strength test results show high potentials of such stabilized mixtures for pavement constructions. Yet further research is still needed to consider the durability and environmental aspects in the future.
