Quick lime is used to dry out damp soils and to improve the clay soils used in earthworks. Lime is also increasingly used to recycle excavated material (trench spoil) from sites in urban areas.
A recent application of lime is the use of hydrated lime in the cement filler which consolidates underground works such as tunnels.
Hydrated lime also improves the performance of the asphalt mixes used for road surfacing. It increases their resistance to stripping, rutting and age-hardening.
