Conventional cement stabilisation
- After 28 day hydration process ≤150 MN/m2: the shrinkage behaviour of cement can result in considerable cracking when binder content is high
- During the hydration process only short crystal needles are formed, which do not allow high bearing strengths
- Stabilized layers allow water to penetrate particularly in cracks and course grained soils), so this presents difficulties in frosty conditions
- Problems with solidification of loamy or clayey soils containing high levels of sulphur associated with high cement content
- No possibility of stabilising soils with high levels of salt
- Without a wearing course, conventionally stabilised surfaces may show signs of damage from thaw and changes in conditions with one year
HITEC Road cement stabilisation
- After 2 days hydration process a load capacity of >150 MN/m2 is established. Total hydration process is approximately 90 days without cracking and a load capacity ≥230 MN/m2
- During the hydration process long crystal needles are formed, allowing very high bearing strengths
- Water does not penetrate, nor any other fluid, into the stabilised layers, guaranteeing safety from frost
- No problems with loamy or clayey soils containing high levels of sulphur associated with high cement content
- Soils with high levels of salt can be stabilised
- No problems from frost, thaw or changes in conditions, as water-resistant base courses may even be constructed from in-situ soils
