Main application in road construction
The following graphics explain the general set-up of a road. The cross section on the left explains the principle of a flexible, flexible composite or rigid composite pavement, for example when constructing with asphalt as a wearing course. The other picture demonstrates the elements and layers of a concrete pavement.
Flexible, flexible composite & rigid composite pavement
In many countries, the technical guidelines for secondary aggregates, especially incinerator bottom ash, permit the use of GRANOVA in the following earthworks and road applications:
- embankments and fill
- unbound mixtures for subbase and base
- hydraulically bound mixtures for subbase and base
The final decision on the use of IBA has to take into account the local environmental conditions.
