ABSTRACT
Utilization of post-disaster pavement materials in Palu City and Indonesian local materials, namely Asbuton Butir Lawele, are expected to synergize well in Asphaltic Concrete Wearing Course (AC-WC) mixture. This study aims to examine the effect of recycled materials (RAP) and granular asbuton on the volumetric properties of the AC-WC mixture. The RAP material used in the mix is 20% of the mixture weight and variations of asbuton used are 0%, 3%, 6% and 9% of the mixture weight. According to laboratory results, it was found that the addition of RAP material and granular asbuton to the AC-WC mixture could affect the volumetric properties of the mix. The value of voids in the mixture (VIM) and voids in mineral aggregates (VMA) will increase as the proportion of asbuton increases. On the other hand, the void filled with asphalt (VFB) will decrease with the increasing number of asbuton. So it can be said that the AC-WC mixture containing RAP with the addition of granular asbuton, will experience volumetric changes compared to the mix without RAP and granular asbuton.
