Hydrate has been used in asphalt concrete to reduce moisture sensitivity and stripping. Recent studies confirm that hydrated lime offers other important benefits:
- Stiffens the binder and asphalt to resist rutting;
- Improves toughness and resistance to fracture growth at low temperatures;
- Changes oxidation chemistry in the binder to reduce age hardening;
- Alters clay fines to improve moisture stability and durability.
All of the above-mentioned properties enhance the durability of asphalt mixtures. Road managers say that hydrated lime increases durability by 25% over the lifetime of asphalt roads, thus reducing the carbon footprint by 23%. Contact us to know more about our hydrated lime, and our expertise.
