The commercial value of black rice husk ash (BRHA) has increased, and it is suitable for use in highway construction. In this study, BRHA waste was ground using a grinding ball mill to fine particles size less than 75μm. Four BRHA contents were considered in the study i.e. 0%, 2%, 4%, and 6% by weight of binder. The asphalt mixture performance of the BRHA was evaluated through Marshall Stability, stiffness, flow, and density test. Test results showed that BRHA can be satisfactorily used as a filler material in order to increases the properties of hot-mix asphalt. Test results also indicate that asphaltic concrete containing 6% BRHA showed excellent performance to Marshall Stability properties |
