Strength and Drainage in Aggregates Mixed with Recycled Materials

Summary:

Researchers compared the suitability of four recycled materials to that of virgin aggregates for use in the construction of road base and subbase layers by evaluating their hydraulic, mechanical and environmental properties. Results show that with the exception of foundry sand, recycled material mixtures were similar to virgin aggregates in drainage characteristics, stiffness, strength and environmental impact, and so are expected to be good substitutes for them as base and subbase materials in road construction.
