Abstract

Abstract Additives added to the flexible pavement mixture aim to increase the strength of the pavement. Limestone which is a sedimentary rock consists of the mineral calcium carbonate (calcite) or the double carbonate of calcium and magnesium (dolomite). The use of limestone in pavement mixtures is expected to increase the performance of Marshall parameters. This study aims to determine the suitability of limestone as a filler for 3 types of pavement mixtures, namely Asphalt Concrete Wearing Course, Hot Rolled Sheet and Split Mastic Asphalt. In this study, the limestone used was sourced from Jorong Durian, Nagari Kamang Mudiak, Kamang Magek District, Agam Regency, West Sumatra Province. The tests were carried out using following variations of limestone; 0%, 25%, 50%, 75%, 100% of the total amount of filler in the mixture. The results of the study using limestone as filler obtained at an optimum content of 29% for AC-WC, 22% for HRS, and 82.5% for SMA. In addition, AC-WC pavement was found to the best increase in Marshall stability performance. Therefore, it can be concluded that limestone from Kamang Mudiak is most suitable to be added to AC-WC pavement mixtures.

石灰石作为填料在各种路面混合物中的性能研究

摘要添加到柔性路面混合物中的添加剂旨在提高路面的强度。石灰石是一种沉积岩，由矿物碳酸钙（方解石）或钙镁双碳酸盐（白云石）组成。在路面混合物中使用石灰石有望提高马歇尔参数的性能。本研究旨在确定石灰石作为填料是否适用于 3 种路面混合物，即沥青混凝土磨耗层、热轧薄板和劈裂玛蹄脂沥青。本研究使用的石灰石产自西苏门答腊省阿甘县卡曼马吉克区纳加里卡曼穆迪亚克的乔龙榴莲。测试使用了以下不同的石灰石：混合物中填料总量的 0%、25%、50%、75%、100%。使用石灰石作为填料的研究结果表明，AC-WC 的最佳含量为 29%，HRS 为 22%，SMA 为 82.5%。此外，还发现 AC-WC 路面的马歇尔稳定性能提高得最好。因此，可以得出结论，卡芒穆迪亚克的石灰石最适合添加到 AC-WC 路面混合物中。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
