Karakteristik struktur dianalisis menggunakan X-Ray Diffraction (XRD). Mikrostruktur dianalisis menggunakan Scanning Electron Microscopy-Energy Dispersive Spectroscopy (SEM-EDS). Analisis sifat fisis yang dilakukan adalah densitas dan porositas. Hasil analisis struktur menunjukkan silika amorf mengalami pergeseran dari 2θ = 22o menjadi 2θ = 21o dan teridentifikasi karbon amorf pada 2θ = 20o . Analisis mikrostruktur menunjukkan seiring penambahan aspal ukuran butir dan gumpalan semakin besar dan retakan semakin banyak. Hasil uji sifat fisis pada komposit memperlihatkan penambahan aspal mengakibatkan nilai densitas meningkat dan porositas menurun. Kata Kunci: aspal, mikrostruktur, sekam padi, silika The composites of silica rice husk and asphalt was prepared with at a ratio of 1:0.4, 1:0.5, and 1:0.6 and heated at the temperature of 150o C for 3 hours. The structure characteristic were analyzed by X-Ray Diffraction (XRD). Microstructure were analyzed by Scanning Electron Microscopy-Energy Dispersive Spectroscopy (SEM-EDS). The analysis of physical properties are density and porosity. The results of the structure shows that silica amorphous shifted 2θ = 22o to 2θ = 21o and amorphous carbon identified at 2θ = 20o . Microstructure analysis shows that the addition of asphalt, the size of the grains and cluster is getting bigger and there are more cracks. Physical properties test results on the composite shows the addition of asphalt results the increasing of density and the decreasing porosity.
