IBAA was spread in 225mm layers, with 4 passes using a 3600kg vibrating roller to achieve ~30% CBR. The embankment slopes were ~60 degrees in some places near the roundabout.
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.
