Roadways, parking lots, embankments, levees, airport runways, land development for new homes, malls or industrial parks….Lime is essential to civil engineers and contractors as they build the world around us.
Carmeuse lime presents a superior solution for the challenges facing design engineers and contractors building roadways, airfields, parking lots, embankments and facing difficult working conditions from wet and weak soil. Lime does this by quickly drying overly wet soil and improving soil strength and other soil properties.
Additionally, lime can be used to stabilize soil containing clay. Lime stabilization generates a long term pozzolanic strength-gaining reaction between lime and the silica and alumina minerals solubilized at high pH from the clay, forming calcium silicates and calcium aluminates. When lime stabilized soil is used under pavement, this long term strength increase can allow for thickness reductions in overlying pavement layers (base course, asphalt), helping to further reduce construction costs.
Carmeuse lime products for soil improvement include:
- High calcium quicklime (granular)
- Dolomitic quicklime (granular)
- Hydrated lime
- EnviroLime® (Lime kiln dust)
Hydrated lime is used as an additive in asphalt. Hydrated lime improves the cohesion of the asphalt binder to the aggregate particles, making the asphalt pavement less sensitive to moisture and reducing "stripping." Hydrated lime retards the asphalt aging process and improves stiffness properties. Hydrated lime helps reduce asphalt pavement rutting and increases fatigue resistance to heavy wheel loads, a cause of pavement cracking. Adding hydrated lime to asphalt significantly increases pavement life and serviceability.
Carmeuse lime products for use in asphalt include:
- Hydrated lime
- Type S hydrated lime
