• The present paper is part of a research study that has been carried since 2005 in the Mackenzie University. This research takes part in the Research Group of CNPq denominated “Sistemas viários (Road Systems)” for use of the sludge from the water or sewage disposal treatment. The study involves procedure of dosage with addition of chemical stabilization products as the hydrated lime or the Portland cement and soil for potential use in workmanships of earthwork ditches. Moreover, this research intends to study the technician-economic-environmental viability of the improvement in the dry sludge generated by the water treatment plant of Taiaçupeba, searching for the stabilization of this material to use as compacted soil in earthwork ditches.
