OPTIBASE
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).
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.
Carbon footprint reduced by at least :
- Optibase: 30% compared to a reference GB3 reference solution
- Optibase XL: 35% compared to a reference solution in GB3 with 30% recycled asphalt aggregate.
- Optibase XL : A high-grade version of Optibase (0/31.5) is possible, local resources allowing.
Tests | 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 |
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
The areas of use of OPTIBASE
- Road structures bearing all types of traffic (heavy, slow, aggressive; slow lanes on highways; bus lanes)
- Logistics and industrial platforms, ports and airports
