| Lime has been used in hot mix asphalt (HMA) to reduce moisture sensitivity .Hydrated lime has long been an acknowledged anti-strip additive for asphalt pavements, it also imparts other important benefits:
a)It stiffens the binder and HMA to resist rutting.
b)It improves toughness and resistance to fracture growth at low temperatures.
c)Lime changes oxidation chemistry in the binder to reduce age hardening.
d)Lime alters clay fines to improve moisture stability and durability.
Lime is an excellent choice for short-term modification of soil properties. Lime can modify almost all fine-grained soils, but the most dramatic improvement occurs in clay soils of moderate to high plasticity. Modification occurs because calcium cations supplied by the hydrated lime replace the cations normally present on the surface of the clay mineral, promoted by the high pH environment of the lime-water system. Thus, the clay surface mineralogy is altered, producing the following benefits:
Plasticity reduction
Reduction in moisture-holding capacity (drying)
Swell reduction
Improved stability
The ability to construct a solid working platform |

Masonary Application |
|
|
| )Lime has been used as a primary ingredient in masonry mortars for centuries, and this important use continues to the present day in both historic and contemporary applications. Mortars madewith lime and cement exhibit superior workability balanced with appropriate compressive strength, as well as low water permeability and superior bond strength. Lime is a major constituent in exterior and interior stuccos and plasters, enhancing the strength, durability, and workability of these finishes. All of these lime applications are supported by ASTM specifications and standards | |
