Road construction included the use of Incinerator Bottom Ash Aggregate (IBAA) 6N granular material, placed at up to 800mm.


IBAA is an extremely cost-effective material when compared to Primary Aggregates and BP UK is working towards a verified Carbon Footprint. There are also advantages logistically when using IBAA due to the low density of the material allowing for fewer vehicle movements as this gives volumetric advantages over primary materials.
