“…Its chemical composition includes 50% silicon dioxide (SiO 2 ), 28% aluminum oxide (Al 2 O 3 ), 12% iron oxide (Fe 2 O 3 ), 6% calcium oxide (CaO), 2% magnesium oxide (MgO), and 2% sulfur trioxide (SO 3 ). This composition reflects the mineralogical nature of bottom ash, making it a potentially effective filler material in asphalt mixtures [ 30 ].…”

“…In terms of density, conventional lime filler typically ranges from 2.2 to 2.5 g/cm 3 , whereas crushed bottom ash demonstrates a higher density of 2.7 g/cm 3 . Chemical composition analysis highlights further disparities between the two materials [30]. Conventional lime filler primarily consists of calcium carbonate (CaCO 3 ), whereas crushed bottom ash comprises a diverse composition.…”

Amid the growing demand for sustainable pavement solutions and the need to incorporate recycled materials into construction practices, this study explored the viability of using crushed thermal power plant bottom ash as a filler in polymer-modified asphalt concrete mixtures. Conventional lime filler was replaced with bottom ash at varying levels (0%, 25%, 50%, and 75%), and the resulting mixtures were evaluated using several performance tests. The optimal replacement level was determined to be 25%, based on the results of the indirect tensile strength (ITS) test. Comparisons between the control mixture and the 25% bottom ash-modified mixture were conducted using the dynamic modulus test, Cantabro test, Hamburg wheel tracking (HWT) test, and tensile strength ratio (TSR) test. The findings indicate that the 25% bottom ash-modified mixture demonstrated improved performance across multiple parameters. The HWT test showed enhanced rut durability, with a recorded depth of 7.56 mm compared to 8.9 mm for the control mixture. The Cantabro test results revealed lower weight loss percentages for the modified mixture, indicating better abrasion resistance. The dynamic modulus test indicated higher resilience and stiffness in both high- and low-frequency stages. The TSR test highlighted improved moisture resistance, with higher TSR values after 10 wet-drying cycles. These improvements are attributed to the fine particle size and beneficial chemical composition of bottom ash, which enhance the asphalt mixture’s density, binder-aggregate adhesion, and overall durability. The results suggest that incorporating 25% crushed bottom ash as a filler in polymer-modified asphalt concrete mixtures is a viable and sustainable approach to improving pavement performance and longevity.

Climate change has caused a surge in abnormal weather patterns, leading to a rise in cracks, plastic deformation, and pothole damage on road surfaces. In order to fabricate a ready-mix admixture of warm asphalt mixture (WMA) for pothole restoration, this study aimed to develop a neutralized anti-stripping material in pellet form by extruding a combination of slaked lime and a liquid emulsifier additive. Slaked lime (1% by weight of aggregate) was chosen for its ability to enhance moisture resistance, while a liquid emulsifier (wax + vegetable oil + surfactant + water) was added to create a pellet-type stripping inhibitor for WMA. After successfully fabricating the pellet admixture, this study evaluated the performance of two asphalt mixtures: conventional Slaked Lime Hot Mix Asphalt (LHMA) and the Pellet-Type Anti-Stripping Warm Mix Asphalt (PWMA). Several compatibility tests were conducted to evaluate the quality of the developed material. The results showed that the fatigue resistance of the developed material (PWMA) improved by over 20%, indicating an extended fatigue life for the pavement. The LHMA and PWMA met the quality standard for asphalt mixtures, with a TSR value of approximately 83%. Both mixtures demonstrated improved rutting resistance compared to HMA. The PWMA required 16,500 cycles, while the LHMA required 19,650 cycles to reach a settlement of 20 mm, indicating better moisture resistance than the control mix (13,481 cycles). The modified mixture performed properly in the Cantabro test, with loss rates below 20%, indicating their ability to retain their aggregate structure. The PWMA also showed superior resistance to plastic deformation, with a 12.5% lower phase angle (35°) at a reduced frequency of 10−3. In general, the application of PWMA not only prolongs the pavement lifespan but also reduces the production temperature by over 20 °C, leading to lower emissions and energy consumption. This makes it an environmentally friendly option for pavement applications and contributes to sustainable road construction practices.

In this research, sodium bicarbonate (NaHCO3) was used as a leavening agent to create air voids in the rubber-vulcanized matrix. The air cavities formed will increase the solubility of rubber vulcanizate in the hot asphalt mixture. 4 and 5 per hundred rubber (phr) NaHCO3 were added to each rubber compound using an open mill. The rubber compound was then vulcanized at 130°C for 15 minutes. Rubber vulcanizate is produced from 4 and 5 phr NaHCO3, each added at 8% to a hot asphalt solution. As a comparison material to determine the performance of NaHCO3, a rubber compound formula was prepared without using NaHCO3. It was found that the AK-01 sample containing NaHCO3 at 4 phr had several characteristics that met the requirements of Indonesian rubber asphalt regulations, including a softening point of 59.7°C, kinematic viscosity at 135°C of 828 cSt, elasticity after recovery of 30%, storage stability, a softening point difference of 2.2°C, and elasticity after the return of the thin film oven test (TFOT) residue test of 40%.
