Construction
150mm of Incinerator Bottom Ash Aggregate (IBAA) Type 1 subbase topped off with a 20mm binder and 6mm surface course. Some sections of the cycleway are to be topped off with a green coloured asphalt.
Benefit
IBAA is an extremely cost-effective material when compared to Primary Aggregates and BPUK 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.
Sustainability
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.
