1,000 tonnes SHW Clause 803 Type 1 Subbase Granite Blend.
Incinerator Bottom Ash Aggregate (IBAA) was supplied from our Blue Phoenix Cornwall Plant at St Dennis. IBAA Type 1 subbase Granite Blend was laid at varying depths of between 150mm and 300mm and was then surfaced with asphalt.
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.
Blue Phoenix now have a CPD, explaining the benefits of IBAA in greater detail, which can be found here.
