Abstract: The paper includes the experimental study of using locally available granite powder as fine aggregate and partial replacement of dust in the preparation of mould under Marshall Stability apparatus with using CRMB (Crumbed rubber modified bitumen) as a binding materials. The percentage of granite powder added by weight was 0, 25, 50, and 100% as a replacement of dust in bituminous concrete layer. The test results show clearly that up to 100% of granite powder can be used in replacement of dust with a increase in stability
