By adding the appropriate quantity of lime to soils which are suitable for lime stabilization, the engineering properties of these soils can be upgraded. Soils from temperate to tropical regions (including lean to fat clays, lateritic to non-lateritic classifications) can be stabilized permanently using lime.
The improved engineering properties include:
- reduced shrink – swell (volume change) potential,
- increased compressive, tensile and flexural strength
- increased stiffness or resilient modulus.
These enhancements improve the performance of the lime-treated layers in the pavement system. The stronger, stiffer and more volumetrically stable lime treated subgrade, subbase or base layers provide protection for weak and deformation-susceptible natural subgrades. The result is, better support for unbound aggregate bases and asphalt surfaces, which enhances their performance.
- reduces the extraction of primary aggregates
- eliminates disposal of excavated soils
- decreases work site traffic by up to 95%, saving the local road network
- reduces construction times and costs.
With our very low dust emission quicklime Proviacal® RD, soil in urban areas can be more easily treated. To deal with clayey soils in dry climate conditions, we have also developed products in liquid form.
Quicklime improves soft soils in the deep soil stabilization process (lime-treated columns), reducing settling and increasing stability.
