The chemical stabilization of the clay soil from the Puraquequara branch located between Manaus and Rio Preto da Eva was evaluated, with the participation of the chemical additives ECOLOPAVI®, EMC²® and TERRAZYME®, as well as the geogrid MacGrid® NET. The natural material and the compositions were characterized according to physical, chemical, mineralogical and mechanical tests, for the curing times of 3 and 28 days. The results showed the natural material as clay soil classified as A-4 and CL. Mineralogical characterization through X-ray Fluorescence identified natural soil with high aluminum oxide content (36.5%) and silicon dioxide (57.2%) of quartz. In accordance with the results of tensile strength (RT), the composition, having the presence of ECOLOPAVI®, indicated the best values related to the soil "in natura" and the other formulations. According to data from Resistance to Simple Compression (RCS), compositions with the participation of additives ECOLOPAVI® and TERRAZYME® obtained the best results. Regarding the RCS assay, using the MacGrid® NET geogrid and the ECOLOPAVI® product, a considerable increase of this parameter was observed for the cure time of 3 (three) days.
