Abstract

This paper presents the experimental results on the utilisation of Rice Hush Ash (RHA) as a replacement for mineral filler in asphaltic concrete pavement in Malaysia. Asphaltic concrete mixes containing RHA at different amounts and control specimens were prepared in accordance to Marshall Mix design, and their performance on stability, flow and bulk density were evaluated. Optimum binder content (OBC) and voids analysis were also conducted to compare performance of RHA at different contents. Results reveal that all RHA mixes have satisfied the Malaysian Public Works Department (JKR) specification on wearing course in regard with Marshall Stability and Flow, especially RHA-75. This material is potentially to be used as partial or fully substitution of mineral filler (stone dust) in pavement construction.
