| Sumario: | The aim of this study is to develop asphalt emulsions incorporating used lubricating oil (OLUC), as a modifier agent, to produce stable emulsions and resulting in cost-effective and environmentally friendly product suitable for paving applications. A central composite design (CCD) is proposed to reduce the experiment’s number. The asphalt emulsions were characterized by Saybolt Furol viscosity, residue by evaporation, settlement and storage stability, sieve test, ductility, and penetration over residue. The results showed that asphalt emulsions, in accordance with all technical specifications, can be produced at 80°C, using 5 minutes as emulsification time and low amounts of surfactant. Moreover, the experiment incorporated OLUC in the composition of asphalt emulsions to obtain new low-cost products for use in paving operations |
