The objective of this research was to assess the mechanical response (resilient and plastic) soil stabilized with petroleum asphalt concrete using emulsion under multi-stage loading. To enhance adhesion film grains, underwent air-drying curing for seven days. Dosage conducted through indirect tensile strength test diametral compression. With optimum content determined in dosage (2% emulsion), additions removals 0.5% from were performed. Consequently, three specimens molded concentrations 1.5%, 2%, 2.5% slow-setting cationic emulsion. These then subjected drained triaxial tests loading, 5 different stress pairs, totaling 50,000 cycles. Analyzing regions defined by total permanent deformation curves allowed studying plastic elastic response, proportionality between these regions, increase a single test, providing more accurate interpretation. Regarding measured deformations, as deviator increased each loading cycle, samples exhibited an deformations compared natural (control). It also observed proportional resilient region, indicating that addition made less rigid but provided cohesion absent before stabilization. Doi: 10.28991/CEJ-2024-010-01-02 Full Text: PDF
