Lime is essential in construction for its versatility and sustainability. It’s used in mortar, plaster, lime concrete, lime wash, and soil stabilization. Hydrated lime, made by adding water to quicklime, is crucial for mortars, plasters, and stabilizing soil, ensuring durable and eco-friendly building practices.
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.
