  Use of Wastewater Treatment Sludge (WTS) as Filler in Hot-Mixed Asphalt Concrete
  Author(s): Nilton de Souza Campelo*, José Francisco Aleixo da Silva and João Bosco Ladislau de Andade
  
  Nowadays, society is increasingly aware that consumer goods are limited, and that waste produced in industrial and residential activities need to be reused. In doing so, the use of new materials is reduced and there is no need for large accumulations of waste in landfills; therefore, the noble destination of a waste brings numerous technical, economic and environmental advantages. This research deals with the use of sludge from the Water Treatment Plant of Ponta do Ismael, in the city of Manaus, state of Amazonas, Brazil, as a filler fraction in hot-mixed asphalt concrete, replacing the mineral filler traditionally used in this region (Portland cement). Five asphalt mixtures were analysed, one as reference (100% Portland cement) and four others, using sludge in the proportions of 25%, 50%, 75% and 100%, by mass, reaching a maximum of 5%, in relation to the total mass of the mixture.
