Analysis of foundry sand for incorporation in asphalt mixtures

Foundry sand is a waste that can be reused as an aggregate and incorporated in asphalt mixtures. In this work, a mix design study of one asphalt mixture was carried out to assess the maximum amount of material that could be used (5%), together with an evaluation of its water sensitivity. Additionally the leaching behavior was evaluated.

Waste Foundry Sand in Asphalt Concrete

in asphalt concrete has been examined by replacing some portions of conventional aggregates with a particular waste foundry sand. A re­ placement level of 15 percent was found to be suitable for this case. Waste foundry sand (WFS) is a by-product of the casting industry that results from the molding and core-making processes.
