Sincethat time, asphalt technology has made strides such that today the equipment,techniques and materials used to build asphalt pavement structures are highlysophisticated.Waste glass has been used in highway construction as an aggregatesubstitute in hot mix asphalt paving. Many countries have recentlyincorporated glass into their roadway specifications, which had encouragedgreater use of the material. While the use of waste glass as filler in hot mixasphalt is still not widely experimented.In this research glass powder is proposed as an alternative to traditional limestone powder (Gubraa) and ordinary Portland cement fillers in hot asphalt mixtures.Where, the effect of using waste glass powder as mineral filler on Marshall Propertiesof hot asphalt concrete mixtures is investigated. Nine mixtures with three types offillers (lime stone powder, ordinary Portland cement and glass powder) and three fillercontents (4%, 7% and 10% by weight of total aggregate) are investigated.The main outcome of this research is the possibility of using glass powder asfiller in hot asphalt concrete mixtures. The optimum glass powder content is 7%.Where it is found that using of glass powder as filler with such replacement leading toproduce asphalt mixture with higher stability (% of increase up to 13%), lower flow(% of decrease up to 39%) and lower density (% of decrease up to 10%) comparing tocorresponding ordinary Portland cement or lime stone powder mixtures.
