Abstract

Roads are very vital access or transportation infrastructure for human movement from one location to another. The materials utilized must fulfill the quality criteria established with respect for economics, availability of natural resources, and efficient distribution. This study used gold mine waste sand as a component of Hot Rolled Sheet Base. (HRS-BASE), this material has considerable potential that has not been utilized properly and is expected to be an alternative material in the area well as one of the steps to handle waste reduction by increasing its function value. Analyzing the characteristics of gold mine waste sand marshall with a composition of Optimum Asphalt Content (KAO) of 7% resulted in a stability value of 975.522 kg, flow of 3.10 mm, Inter-Aggregate Cavities (VMA) of 18.600%, Cavities in the Mixture (VIM) of 3.221%, Cavities Filled with Asphalt (VFB) of 82.689%, and Marshall Quotient of 314.712kg/mm.
将 Penda Pilang 村的金矿废砂用作水基混合物
道路是人类从一个地点前往另一个地点的重要通道或交通基础设施。所使用的材料必须符合经济、自然资源可用性和有效分配等方面的质量标准。本研究使用金矿废砂作为热轧薄板基层的组成部分。(这种材料具有相当大的潜力,但尚未得到适当利用,有望成为该地区的一种替代材料,也是通过提高其功能价值来减少废物的步骤之一。对最佳沥青含量(KAO)为 7% 的金矿废砂马歇尔特性进行分析后发现,其稳定值为 975.522 千克,流动度为 3.10 毫米,集料间空隙(VMA)为 18.600%,混合料空隙(VIM)为 3.221%,沥青填充空隙(VFB)为 82.689%,马歇尔商数为 314.712 千克/毫米。
