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.
