Construction of a 450 metres of adoptable road with footpaths.
800 tonnes of SHW Clause 803 Type 1

IBAA was supplied from our Blue Phoenix Severnside Plant at Avonmouth. Type 1 was used on the roads, pathways and in the compound areas to construct a flat and stable surface for car parking. The roads were dug up to 700mm deep for the road box formation (cut and fill procedure). Type 1 material was then installed for the capping layer inside the road at 200mm then building up levels from underside of kerb line and road construction to underside of asphalt.
Footpaths were also constructed with Type 1 material being used as a capping layer of 300mm – 500mm.
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.
The extraction of primary aggregates for construction and transport to construction sites places enormous pressure on the environment. Mineral mining accounts for 2.8% of the global greenhouse gas emissions. The use of manufactured aggregates from IBA prevents landfilling, mining of virgin raw materials and contributes to the circular economy.
