Comparison chart
Road pavement design: conventional method vs. CONSOLID Nanotechnology.
| Aspect | Conventional method | CONSOLID Nanotechnology |
|---|---|---|
| Soil types | Limited use in certain regions. | Not limited to a specific region by group classification. |
| Use of in-situ soil | None. | Uses the in-situ soil. |
| Earthworks | Yes. Soil replacement is extremely costly and good replacement materials are increasingly scarce. | Using in-situ soil reduces construction and maintenance costs and the total cost of the road. |
| Chemical hydration | None. | Allows complex minerals (Ca-Al-S, Ca-Si, Ca-Al-Si, etc.) to form with no risk of expansion, aggressive exothermic reactions or cracking. |
| Pavement design | Used according to pavement design, never as a wearing course. Goal: increase the CBR of the stabilized layer. | Produces a strong, durable base with high bearing capacity, allowing thinner stabilized and upper layers. |
| Long-term maintenance | Depends on application type, climate, temperature, dosage and soil. Cracking is very likely and maintenance very expensive. | Maintenance is greatly reduced, to the point of being almost non-existent: the total cost is usually the initial cost. |
| Shrinkage | Associated with shrinkage cracking. | Strength is gained over a longer period, with no shrinkage cracks. |
| Moisture | Moisture variation during application affects strength gain. | Activates the soil’s own cohesive forces and inhibits water absorption. |
| Material | Variability of untreated material dramatically affects strength. | Optimizes the in-situ soil: over 30% savings in time and hauling. |
| Plasticity | Active clays hinder the reaction, giving low strength gains. | Multiplies bearing capacity 2 to 20 times and lowers the plasticity index. Works from sands to clays (PI > 10%). |
| Application time | Rushed compaction or partially placed material gives poor results. | Fast, simple application: up to 3,000 m² per day. |
| Climate | Thermal cracking causes structural problems and lets water in. | Unaffected by climate changes (cold-heat, contraction-expansion). |
| Opening to traffic | Time lost to curing and road closures. | Can open to traffic once compaction is done; 2 hours later is recommended. |
| Environment | Requires quarries, landfills and granular layers or geogrids. | Non-polluting, treated soil is reusable, helps prevent erosion and needs no granular layers or geogrids. |
In conclusion
CONSOLID Nanotechnology has many advantages over the conventional method. Above all, it works with the in-situ soil, which makes it eco-friendly; its increased bearing capacity makes roads durable and reduces maintenance practically to zero. That capital can be used to build new roads, helping the country’s economic development.
