N2 - High voids in hot mix asphalt (HMA) can increase sensitivity to moisture, resulting in premature failure of asphalt pavements. The use of artificial aggregates as a substitute for natural aggregates has been considered in this paper to optimize air voids that meet the requirements. The reason is that natural aggregates are non-renewable raw materials and their availability continues to decrease. This study aims to determine the effect of replacing some natural aggregates with artificial aggregates on air voids. This experiment assessed 2 sets of HMA standard gradations, namely the Bina Marga standard (Indonesian standard) and the Federal Aviation Administration (FAA) standard. For each set, 2 different raw materials are used, namely: 1) asphalt mixture using 100% natural aggregate and 2) asphalt mixture using a combination of 25% artificial aggregate and 75% natural aggregate. The analysis includes volumetric mixes, such as VIM (voids in mix), VMA (voids in mineral aggregates), and VFA (bitumen filled voids). The results of the analysis found that the replacement of natural aggregates with artificial aggregates affected the cavities formed in the asphalt mixture. HMA that uses natural aggregates, shows VMA, VFA and VIM that meet the requirements for pavement surface materials.
