The characteristics of municipal incinerated bottom ash (MIBA) and its performance in road pavement applications is assessed through systematic analysis and evaluation of the global experimental data. MIBA has been used in unbound, hydraulically and bitumen bound forms. As unbound material, after processing, MIBA exhibits suitable mechanical properties for use as capping, fill and sub-base material, which has been successfully demonstrated in field
testing. In hydraulically bound form, MIBA can be a viable aggregate component in subbase and roadbase layers at low to moderate contents, depending on the performance requirements and binder content. As bituminous bound aggregate in roads, the material can be fit for use at low contents, which is reinforced by a number of completed case studies, with the allowable MIBA fraction controlled by the voids contents, abrasion resistance and bitumen content
