PERFORMANCE TEST OF DIFFERENT TYPES OF WASTE AS PARTIAL REPLACEMENT OF CEMENT IN HOT ASPHALT MIX

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).
