Assessment of photocatalytic, superhydrophobic and self-cleaning properties on hot mix asphalts coated with TiO₂ and/or ZnO aqueous solutions
Photocatalytic, superhydrophobic and self-cleaning capabilities were promoted on AC 6 and AC 14 asphalt mixtures by spraying of TiO₂ and/or ZnO. Initially, physicochemical and morphological properties of bitumen samples were evaluated by Fourier Transform Infrared Spectroscopy and Atomic Force Microscopy after the solution spraying of TiO₂, ZnO and TiO₂ ZnO. Then, to assure those capacities, Water Angle Contact and Photocatalytic Efficiency tests were carried out on both mixtures. Finally, mixtures were assessed mechanically through Indirect Tensile Strength. Photocatalytic, superhydrophobic and self-cleaning properties were guaranteed for AC 14 with TiO₂ and TiO₂ ZnO and AC 6 with TiO₂ ZnO without deteriorations.
