One of the major fillers used in HMA is cement. With the extensive use of cement inmortars/concrete, there have been some environmental concerns in terms of damage caused bythe 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 journaloutlines the ongoing research on different waste materials partial replacement of cement as fillerused in hot mix asphalt mixes. Many studies regarding their effects on bituminous mixes werealso analysed in combination with cement filler mastic. This project summarizes the interactionof 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 bituminousmixes. Marshall properties such as stability, flow value, unit weight, air voids, are used todetermine optimum waste material content for the used grade of bitumen (100/120).
