ABSTRACT
Red mud is a solid waste generated at aluminum production. Currently in Brazil this sub-product does not receive appropriate destination and is stored in deforested areas. Annually, approximately 11 million tons of red mud are generated just in Brazil and represent a great imminent risk of pollution and contamination. The large amount of red mud generated by aluminum industry has motivated researchers to develop methods for using this residue. Studies show the possibility of using red mud compound ceramic materials, however, there is a lack of research in other areas, such as applied to pavements. On the other hand, more than 50% of Brazilian highways are in poor condition, especially in the north, where high temperatures favor permanent deformation in pavement. In this scenario, this paper compares permanent deformation results of asphalt mixtures composed by 7% filler, varying the type of filler (red mus and stone powder). For this, red mud characterization tests were performed. The results showed that red mud can improve the resistence of asphalt mixtures.
