摘要
在马来西亚，在路面混合料中使用爆破废物是一种新的替代方案。因此，本研究旨在探讨爆破废物在道路建设中作为沥青混合物添加剂的潜力。研究了爆破废添加剂的添加比例，分别为0%、5%、10%、15%和17%。通过马歇尔试验获得了每种混合物的参数值。马歇尔试验共准备了5组样品，每组包含3个样品。从测试结果来看，所有爆破废物在沥青混合物中作为添加剂的百分比都通过了公共工程部(Jabatan Kerja Raya或JKR)的规范。爆破废石掺量为10%为最佳掺量，稳定值为82.5kN，而对照样品的稳定值为37.7kN。10%样品的流量和马歇尔商值分别为4mm和20kN/mm。本研究得到的所有数值均符合JKR规范，说明爆破废弃物在提高沥青混合料规范值方面具有很大的潜力。
Effect of Blasting Waste as An Additive in Bitumen Mixtures
The use of blasting waste in road pavement mixes is one of the new alternatives in Malaysia. Therefore, this study aimed to look at the potential of blasting waste as an additive in bitumen mixtures in road construction. Several percentages of blasting waste additive were studied, namely 0%, 5%, 10%, 15% and 17%. The parameter values of each of these mixtures were obtained through the Marshall test. A total of five sets of specimens were prepared for the Marshall test, with each set containing three samples. From the test result, all the percentages of blasting waste as an additive in the bitumen mixture passed the Public Works Department (Jabatan Kerja Raya or JKR) specifications. It was also concluded that 10% of blasting waste as an additive is the optimum value, with a stability value of 82.5kN as compared to the stability value of the control sample at 37.7kN. The flow and Marshall Quotient values for the 10% sample were 4mm and 20kN/mm, respectively. All values obtained from this study were in accordance with JKR specifications, indicating that blasting waste has great potential in improving the specification values of bitumen mixtures.
