Optibase
The most cost-effective structure
Optibase is a high-performance mix for sub-grade courses.
Thanks to its optimized formula, the thickness of the base course and the road base course can be reduced significantly compared to classic mixes (by up to 25% compared to a Class 3 road base asphalt).
Carbon footprint reduced by average :
- Optibase: 35% compared to a reference solution in road base asphalt
- Optibase XL: 45% compared to a reference solution in road base asphalt
- Optibase XL : A high-grade version of Optibase (0/31.5) is possible, local resources allowing.
| Test | 0/14 - 0/20 | 0/31.5 |
| Complex modulus 15 °C – 10 Hz NF EN 12697-26 (MPa) |
12 000 - 15 000 | ≥ 11 000 |
| Fatigue test with alternate bending 10 °C – 25 Hz NF EN 12697-24 (μdef) |
≥ 110 | ≥ 100 |
In terms of mechanical characteristics, Optibase outperforms all standard classes of road base asphalt. For a lower cost, it offers structural performance levels comparable to those of a high modulus asphalt.
The advantages of Optibase
- Optimized pavement design significantly reduces the thickness of the various courses, and therefore also reduces the depth of deconstruction or excavation work
- Up to 50% recycled aggregate
- Optibase can be made hot or warm for the same level of performance
