Lime Stabilisation

Lime is a very effective binder for plastic soils. Usually in clays there is a degree of pozzolemic  material which chemically reacts with calcium hydroxide to forma cementitious material.

Lime is usually used in subgrades or unsealed roads resulting in

• Improved strength

• Improved workability

• Elimination of swelling

• Improved grading

• Greatly improved water resistance

These improved properties achieve major advantages in pavements.

Subgrades are:

• Stronger therefore reduce the pavement thickness as stabilised material can be treated as a lower subbase layer

• Improve water resistance of overall pavement.

• A working platform that allows construction to proceed in wet weather

Unsealed Roads

• Require less maintenance

• Greatly reduced dust generation

• Far safer driving surface especially in wet weather
