Market Needs
Lime serves multiple purposes in asphaltic concrete, primarily as a stabilizer, anti-stripping agent, and drying agent, contributing to improved performance and sustainability in road construction.
Solution
In asphaltic concrete mixes, hydrated lime (Ca(OH)₂) is added in small amounts (around 1-2% by weight) to enhance performance. It improves adhesion between asphalt binder and aggregates, stabilizes fine particles to reduce moisture sensitivity, and acts as a drying agent for better workability. Hydrated lime helps increase pavement durability, reduce rutting, and improve resistance to moisture damage, requiring careful mix design for optimal results.
