“…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]. Waste materials, such as palm fuel ash, rice husk ash and coconut shell rattan, have been utilized as additives in composite materials, and some waste materials have been used as nanomaterials [24][25][26][27][28][29][30], producing satisfactory results with improved performance. Composite materials are also sustainable structures by reducing waste materials [31][32][33].…”

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.

“…In addition, the use of bioCS as a RA binding rejuvenation agent can be used and research can be continued on a field scale [35]. Apart from that, modified asphalt with nano coconut shells has good strength and quality and biodegradable properties in various composite structures [29,[36][37][38].…”

“…The mechanical properties of CSC can also be improved by con ning the concrete with hot-rolled steel and cold-formed steel (Gunasekaran et al 2019). CSs can be utilized in asphalt concrete with a maximum limit of 10% replacement for coarse aggregate (Jeffry et al 2016).…”

Coconut shell concrete is a lightweight concrete produced from waste coconut shells. In this paper, the bond strength between lightweight coconut shell concrete with silica fume and circular steel tube was experimentally investigated. Coconut shells were used as coarse aggregates and silica fume as the mineral admixture. Two concrete mixes with and without silica fume were tested for bond strength. The parameters of study were the D/t ratio, interface length, and the interface type (roughened steel surface and internal stiffeners). The steel tube thickness (2.5mm) was kept constant, and the external diameter (88mm, 114mm and 140mm), and the length of the tubes (300mm and 400mm) were varied. Silica fume significantly increased the bond strength and was evidenced through the micro-structural study of the interface with a scanning electron microscope. Higher bond strength was obtained in columns with a low D/t ratio, and increasing the interface length could not improve the bond strength. The combination of silica fume with internal stiffeners improved the bond strength by 5.33–27% more than the combination of roughened steel surface and silica fume. Test results were compared to EC4 and ANSI/AISC 360 recommendations. The test values exceeded code design bond strengths.

“…Over the past decades, many studies explored the effects of natural additives on the properties of conventional bitumen [1][2][3]. The current use of coconut shell (CS) as a modifier in bitumen or replacement of aggregate in asphalt mixture has drawn considerable attention among researchers [4][5][6]. However, the use of charcoal from CS as a modifier in bitumen is uncommon in Malaysia.…”

Environmental pollution caused by abundant wastes from agricultural activities has increased in recent years because of increased productivity. Agricultural waste recycling has been employed to solve this problem. Coconut shell charcoal (CSC) ash is a by-product of coconut shell (CS) used as a bitumen modifier to enhance the properties of the binder. This study investigated the effect of fineness charcoal ash from CS on the rheological properties of bitumen. Penetration, softening point, and viscosity tests were performed to determine the properties of the binder. Laboratory simulation of aging called rolling thin film oven test was applied in this study. CSC at different sizes (< 75μm, 75–150μm, and 150–300μm) was added to replace bitumen 60/70 PEN at 0%, 10%, 15%, and 20% by weight of the binder, respectively. Result showed that the bitumen became more viscous and that the softening point of bitumen increased, whereas the rate of penetration decreased when CSC was incorporated. CSC at a proper amount improved the resistance of bitumen to temperature susceptibility. In addition, the modification of bitumen can relieve the effect of aging. Modified bitumen shows better result when incorporated with the finest particle (< 75μm) of CSC compared with other sizes.
