“…In addition, palm shell ash has a dominant silica (SiO2) content to be used as an economical and environmentally friendly filler. Modification of asphalt with natural materials has been widely carried out, such as modification of asphalt with natural materials, natural rubber, asbuton, zeolite and so on [6][7][8][9][10][11][12][13][14][15][16][17][18][19]. Current research focuses more on waste materials, reducing asphalt mixing temperatures, and energy replacement such as recycled RAP, crumb rubber, recycled aggregate, biochar, palm oil fuel ash, and bio-based binders can help reduce the environmental impact of production and maintenance of asphalt pavements as well as lower costs and improved performance of the mixture when compared with conventional materials [20][21][22][23].…”

One innovation in creating new materials that have superior properties compared to large-sized materials is to use nanotechnology. The uniqueness of nano materials is that the smaller the size of the material, the greater the surface area and performance characteristics of the material in the asphalt mixture. This research develops nano technology in asphalt pavement construction by making nano material from palm shell ash waste. The aim of this research is to determine the effect of adding palm shell ash nano material as a substitute for asphalt in the AC-WC mixture. The research method was carried out by testing the morphological characterization of the palm shell ash nano material using X-Ray Fluorescence (XRF) testing and Scanning Electron Microscope (SEM) testing, then continuing with testing the characteristics of the mixture using the Marshall testing method. The nano material used is palm shell ash material obtained from palm shell burning waste originating from Riau which is then processed into Nano Palm Shell Ash (NPSA) material using a ball mill. The asphalt used is Pen 60/70 asphalt produced by Pertamina. The use of NPSA material in asphalt modification with NPSA variations of 1%, 2% and 3% can improve the performance of marshal characteristics compared to conventional asphalt mixtures. It can be seen that the stability, flow, VFA and MQ values increase with increasing NPSA percentage in asphalt. Meanwhile, the VIM and VMA values decreased along with the increase in the NPSA percentage in asphalt. In addition, increasing the percentage of NPSA in asphalt can reduce the use of optimum asphalt content compared to conventional asphalt mixtures. Utilizing palm shell ash waste is the best alternative for improving the performance of asphalt in mixtures and is environmentally friendly and economical.

Pengembangan aspal modifikasi dengan menggunakan nano teknologi merupakan salah satu inovasi dalam menciptakan sebuah material baru yang berskala nano meter yang mempunyai sifat lebih unggul dari material yang berukuran besar. Keunikan dari nano material yaitu semakin kecil ukuran material maka luas permukaan dan kinerja karakteristik material dalam campuran aspal semakin meningkat. Penelitian ini bertujuan untuk mengetahui pengaruh dari penambahan Nano Abu Cangkang Sawit (NACS) pada bitumen terhadap sifat reologi dasar aspal.. Metode penelitian menggunakan metode pengujian di laboratorium. Material nano yang digunakan adalah material abu cangkang sawit yang diperoleh dari limbah sisa pembakaran cangkang sawit yang berasal dari Riau yang kemudian diproses menjadi Nano Abu Cangkang Sawit (NACS) di laboratorium Kimia ITB. Aspal yang digunakan yaitu aspal Pen 60/70 produksi Pertamina. Penggunaan material NACS dalam modifikasi aspal dengan variasi 1%, 2%, dan 3% NACS dapat menurunkan nilai penetrasi ,meningkatkan titik lembek, menurunkan nilai daktilitas dan menurunkan suhu pencampuran dan suhu pemadatan seiring dengan bertambahnya persentase NACS..

The development of asphalt modified with natural rubber, specifically Standard Indonesian Rubber (SIR) 20, improves the overall performance of asphalt. However, the mixing process presents challenges that can result in higher mixing and compaction temperatures. To overcome this, our research utilizes SIR 20 in micro form. This study aims to assess the effects of incorporating Micro Rubber SIR 20 (MR SIR 20) into bitumen on the fundamental rheological properties of asphalt and to explore the morphological characteristics of MR SIR 20 modified asphalt. The research was conducted through laboratory tests, examining key rheological properties such as penetration, softening point, ductility, and viscosity. For morphological analysis, tests included Scanning Electron Microscopy (SEM), Energy Dispersive X-Ray Spectroscopy (EDS), and Fourier Transform Infrared Spectroscopy (FTIR). The laboratory tests involved adding MR SIR 20 in concentrations of 7%, 9%, and 11% to Pen 60/70 asphalt. The findings indicated that as the MR SIR 20 content increased, penetration values decreased, softening points rose, ductility diminished, and mixing and compaction temperatures were reduced. The decrease in penetration is attributed to the higher MR SIR 20 content, which enhances the absorption of lighter asphalt fractions and improves homogeneity. The rise in softening point compared to standard Pen 60/70 asphalt signifies a successful modification, driven by increased asphaltene and resin content and a reduction in maltene content in the bitumen. Consequently, MR SIR 20 modified asphalt can speed up the mixing process and lower the required mixing and compaction temperatures. SEM analysis of MR SIR 20 revealed a rounded morphology, uniformly distributed across the surface. EDS analysis identified sulfur, potassium, calcium, and zinc as the dominant elements in MR SIR 20, which play a vital role in enhancing the properties of Pen 60/70 asphalt in the mixture. Additionally, FTIR analysis showed the presence of alkane functional groups in MR SIR 20.
