Investigating the Effect of Glass Waste Powder on Asphalt Mixture Performance

In this research, by reviewing the researches and articles, waste glass powder is investigated on the performance of asphalt mixture. In the last decade, these researchers have been using crushed glass in construction programs to prevent waste glass from being used as protective supplements and reducing the environment in construction. Crushed glass has been studied for use as materials in base and sub-base pavement layers, as well as concrete. Glass is the only material that can be completely recycled. This material is prepared by melting quartz sand, soda and lime, and also glass pieces. The glass game is collected as one of the recycled components. It is non-metallic and neither can nor does it burn, so its recovery is possible. Therefore, it is used in road construction as a substitute for stone materials in asphalt pavement with warm asphalt mixture. It showed that the addition of glass powder increases the stability of the mixture, because the glass powder filler improves the Marshall Stability results for all mixtures compared to Portland cement or limestone powder fillers. The results showed that the powder from the mixture decreases against the glass. Also, the obtained results investigated the suitability of glass as filler.
