- Abstract
Inadequate disposal of wastes in ETA and ETE is an environmental crime owing to high potential waste pollutant. The management of crude sludge is a relevant task because of epidemiological risks and the presence of heavy metals. Wastes are treated by stabilization and solidification techniques. Current study monitors the environmental impact caused by sludge wastes in pavement layers and sub-layers by building a miniature model of mixtures soil+sludge+stabilizer, for ETE and ETA sludge. Parameters humidity, pH, calque and heavy metal concentration were analyzed during the year. Results indicated that the stabilization/solidification process with sludge wastes for pavements is a solution that may solve economic and environmental issues.
