Abstract

The increasing development of road infrastructure in Indonesia has led to a significant rise in the demand for asphalt pavement materials every year. The continuous use of conventional materials, especially aggregates and limestone filler, causes environmental impacts such as land degradation, increased carbon emissions, and the accumulation of non-biodegradable construction waste. One potential waste material that can be utilized is ceramic powder waste, which has physical and chemical characteristics similar to conventional fillers. However, studies regarding the utilization of ceramic powder waste as a filler in Cold Paving Hot Mix Asbuton (CPHMA) mixtures are still limited. This study aims to analyze the Marshall characteristics of Cold Paving Hot Mix Asbuton (CPHMA) mixtures using ceramic powder waste as a filler substitution and to evaluate their compliance with the 2018 General Specifications of Bina Marga. The research was conducted experimentally through laboratory testing of aggregate characteristics, B50/30 asphalt, and ceramic powder waste filler. Furthermore, CPHMA specimens were prepared using filler variations of 1%, 1.5%, and 2%, followed by Marshall testing to analyze stability, flow, Voids in Mix (VIM), Voids in Mineral Aggregate (VMA), Voids Filled with Bitumen (VFB), Marshall Quotient (MQ), and Residual Marshall Stability (RMS). The test results were analyzed and compared with the requirements of the 2018 General Specifications of Bina Marga. The results showed that ceramic powder waste has the potential to be used as an alternative filler in CPHMA cold asphalt mixtures. All filler variations satisfied the Marshall requirements based on the 2018 General Specifications of Bina Marga. The 1.5% filler variation produced the most optimal mixture characteristics with a stability value of 510 kg, flow of 5.1 mm, VIM of 8.9%, VMA of 24.5%, VFB of 63.9%, and Residual Marshall Stability of 128%. The utilization of ceramic powder waste also has the potential to support sustainable development through the use of non-biodegradable waste as a more environmentally friendly road pavement material.

Review

This study addresses a pertinent and growing concern within the road infrastructure sector in Indonesia: the environmental impact of conventional asphalt pavement materials. With the increasing demand for road construction, the reliance on aggregates and limestone filler contributes significantly to land degradation, carbon emissions, and the accumulation of non-biodegradable waste. The paper effectively identifies ceramic powder waste as a promising alternative, possessing comparable physical and chemical properties to traditional fillers, yet notes a clear research gap in its application within Cold Paving Hot Mix Asbuton (CPHMA) mixtures. This framing establishes a clear motivation for the research, highlighting its relevance to both material science and environmental sustainability. The methodology employed is experimental and laboratory-based, focusing on a rigorous assessment of Marshall characteristics. The researchers meticulously evaluated aggregate, B50/30 asphalt, and the ceramic powder waste filler, subsequently preparing CPHMA specimens with varying filler percentages (1%, 1.5%, and 2%). A comprehensive suite of Marshall tests, including stability, flow, VIM, VMA, VFB, MQ, and Residual Marshall Stability, was conducted, with results meticulously compared against the 2018 General Specifications of Bina Marga. Crucially, the findings demonstrate that ceramic powder waste is indeed a viable alternative filler, with all tested variations meeting the specified Marshall requirements. The study successfully pinpoints the 1.5% filler variation as yielding the most optimal mixture characteristics, evidenced by its robust stability (510 kg) and commendable Residual Marshall Stability (128%). The implications of this research are significant, particularly in advocating for more sustainable road construction practices. By successfully demonstrating the efficacy of ceramic powder waste as a CPHMA filler, the study provides a tangible pathway for utilizing non-biodegradable industrial waste, thereby reducing environmental burden and promoting a circular economy within the construction industry. This aligns strongly with global efforts towards sustainable development goals by transforming waste into a valuable resource for environmentally friendly road pavement materials. Future research could potentially explore the long-term performance and durability of these mixtures under various field conditions to further validate their widespread adoption, building upon the strong foundational insights provided by this laboratory-based investigation.
