Shrinkage is a common cause of cracking in various types of concrete. Several factors can affect the degree of shrinkage, including the use of waste materials like municipal solid waste incineration bottom ash (MSWI-BA) in concrete production. Incorporating MSWI-BA can increase the recycling rate of waste materials in construction, making it a sustainable option. This study particularly focuses on pervious concrete, which has gained popularity as a pavement material for low-volume road applications due to its favorable environmental characteristics. In this study, MSWI-BA aggregates are used to replace natural aggregates (NA) at varying percentages (0%, 25%, 50%, 75%, and 100% by volume). To assess the effect, three volume stability tests (drying, autogenous shrinkage, and expansion) were performed for each mix. These tests were monitored daily for the first week, then once a week until 90 days. The results showed that drying shrinkage increased with MSWI-BA content, especially during the first 2 weeks. However, MSWI-BA aggregates improved autogenous shrinkage by increasing the concrete mix's moisture content. Additionally, expansion decreased with increased MSWI-BA content because porous MSWI-BA could accommodate the expansion volume.
