Abstract

One of the major fillers used in HMA is cement. With the extensive use of cement in mortars/concrete, there have been some environmental concerns in terms of damage caused by the extraction of raw material and Carbon dioxide (CO2) emission during cement manufacture. This has brought pressures to reduce the cement consumption in the industry. This journal outlines the ongoing research on different waste materials partial replacement of cement as filler used in hot mix asphalt mixes. Many studies regarding their effects on bituminous mixes were also analysed in combination with cement filler mastic. This project summarizes the interaction of Waste materials partial replacement of cement with different percentages 0%, 25%, 50%, 75%, 100% and finding out the optimun percenetage of waste material i.e: GGBS, Flyash, Concrete dust, Metakaolin and Marble powder as partial replacment of cement in bituminous mixes. Marshall properties such as stability, flow value, unit weight, air voids, are used to determine optimum waste material content for the used grade of bitumen (100/120).

不同类型废弃物在热沥青混合料中部分替代水泥的性能试验

水泥是HMA中使用的主要填料之一。随着水泥在砂浆/混凝土中的广泛使用，在水泥生产过程中，原材料的提取和二氧化碳(CO2)的排放造成了一些环境问题。这给水泥行业带来了减少水泥消耗的压力。本文概述了在热拌沥青混合料中使用不同废料部分替代水泥作为填料的研究进展。并结合水泥填料胶浆对沥青混合料的影响进行了分析。本项目总结了0%、25%、50%、75%、100%不同比例的废旧材料部分替代水泥的相互作用，找出了沥青混合料中废旧材料GGBS、粉煤灰、混凝土粉尘、偏高岭土和大理石粉部分替代水泥的最佳比例。马歇尔性能，如稳定性，流量值，单位重量，空气空隙，被用来确定沥青使用等级(100/120)的最佳废料含量。
