Environmental conditions for use
The construction of an embankment with secondary aggregates such as GRANOVA IBA must be carried out in accordance with the Secondary Aggregate Directive. For this purpose, the local framework conditions must be considered:
- location of the construction project in regard to water protection areas and hydrogeologically sensitive areas
- distance between highest expected groundwater level and secondary aggregate formation (defined as groundwater-free percolation zone)
- type of soil above groundwater-free percolation zone
Based on this data, a decision can be made using the German application slider for secondary aggregates as to whether the use of incinerator bottom ash is permissible.
