For over 100 years, lime has been used in hot mix asphalt (HMA) as a mineral filler and anti-stripping additive. Adding lime into HMA is proven to extend the life of a highway, in turn reducing long-term costs. It’s why road contractors and highway agencies across the UK rely on our lime products and solutions to improve performance.

When used in asphalt our high purity Limbux hydrated lime (calcium hydroxide) enhances binder viscosity, increases stiffness, tensile strength, compressive strength and resistance to rutting. While suitable for use alone, Limbux can also be used with other additives to deliver optimum bulk density, consistency and resistance to temperature changes in asphalt.
