Incinerator bottom ash aggregate (IBAA) is the result of putting IBA through a process that removes much of the metal content and prepares the aggregate sizes. It has been an accepted and widely used sustainable aggregate both in the UK and on the continent for many years. Over five million tonnes have been used as sub-base and capping material in numerous applications over that 10-year period.
It is a sustainable and cost-effective option that complies with European and British Standards as well as sections of the Specification for Highway Works.
Applications
Our IBAA is a manufactured aggregate compliant with various material designations from the Specification for Highway Works 600 and 800 series. It may also be used as a constituent of a granular material compliant to the same SHW 600 and 800 series. Manufactured aggregates must comply with the same requirements as primary materials. Given this, users and specifiers can choose a sustainable option such as IBAA, with the confidence that it will be fit for purpose and perform comparably with a primary material.
