Lime quickly improves the soil condition during construction and can add long term improvements to key soil properties. Lime can be used to stabilize pavement subgrade soil containing clay which generates long term strength and reduces swell potential.
It’s difficult to reach the soil moisture and compaction requirements established by the project civil or geotechnical engineer. Soil modification reduces the soil placticity, aids compaction and increases strength.
Muddy site conditions make for difficult working conditions making access difficult for construction vehicles. Wet, poorly compacted soil makes for poor pavement support and embankment/fill. Soil drying reduces the soil moisture content improving accessability of the roadway.
