Road Construction - Recycling Centre, Hartcliffe Way, BristolDownload Case Study
Road construction project.
1,000 tonnes of SHW Clause 803 Type 1 IBAA
Bristol Waste Company
Construction of a split-level household recycling and re-use centre. Type 1 IBAA sub-base was used as an alternative to a primary aggregate. The road application was constructed with a layer of 150mm of Type 1 and Overlayed by 200mm 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.
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.
